Fix this with a very simple round robin allocator. [...]
This patch, adding NR_ALLOC_BATCH, eventually landed in mainline as commit 81c0a2bb515fd4daae8cab64352877480792b515 (2013-09-11).
I recently upgraded a Debian testing system from a 3.11 kernel to 3.12, and it started to exhibit "strange" issues, which I then bisected to this patch. I'm not saying that the patch is faulty, as it seems to be working fine for everyone else, so I rather assume that something in a (vastly?) different corner of the kernel (or my hardware?) is broken. ;-)
The issue is that when X.org/lightdm starts up, there are "garbled" section on the screen, for example, rectangular boxes that are just black or otherwise "distorted", and/or sets of glyphs (corresponding to a set of characters; but not all characters) are displayed as rectangular gray or black boxes, and/or icons in a GNOME session are not displayed properly, and so on. (Can take a snapshot if that helps?) Switching to a Linux console, I can use that one fine. Switching back to X, in the majority of all cases, the screen will be completely black, but with the mouse cursor still rendered properly (done in hardware, I assume).
Reverting commit 81c0a2bb515fd4daae8cab64352877480792b515, for example on top of v3.12, and everything is back to normal. The problem also persists with a v3.14 kernel that I just built.
I will try to figure out what's going on, but will gladly take any pointers, or suggestions about how to tackle such a problem.
The hardware is a Fujitsu Siemens Esprimo E5600, mainboard D2264-A1, CPU AMD Sempron 3000+. There is a on-board graphics thingy, but I'm not using that; instead I put in a Sapphire Radeon HD 4350 card.
I went over this code change repeatedly but I could not see anything directly that would explain it. However, this patch DOES change the way allocations are placed (while still respecting zone specifiers like __GFP_DMA etc.) and so it's possible that they unearthed a corruption, or a wrongly set dma mask in the drivers.
Ccing the radeon driver guys. Full quote follows.

This patch, adding NR_ALLOC_BATCH, eventually landed in mainline as commit 81c0a2bb515fd4daae8cab64352877480792b515 (2013-09-11).
I recently upgraded a Debian testing system from a 3.11 kernel to 3.12, and it started to exhibit "strange" issues, which I then bisected to this patch. I'm not saying that the patch is faulty, as it seems to be working fine for everyone else, so I rather assume that something in a (vastly?) different corner of the kernel (or my hardware?) is broken. ;-)
The issue is that when X.org/lightdm starts up, there are "garbled" section on the screen, for example, rectangular boxes that are just black or otherwise "distorted", and/or sets of glyphs (corresponding to a set of characters; but not all characters) are displayed as rectangular gray or black boxes, and/or icons in a GNOME session are not displayed properly, and so on. (Can take a snapshot if that helps?) Switching to a Linux console, I can use that one fine. Switching back to X, in the majority of all cases, the screen will be completely black, but with the mouse cursor still rendered properly (done in hardware, I assume).
Reverting commit 81c0a2bb515fd4daae8cab64352877480792b515, for example on top of v3.12, and everything is back to normal. The problem also persists with a v3.14 kernel that I just built.
I will try to figure out what's going on, but will gladly take any pointers, or suggestions about how to tackle such a problem.
The hardware is a Fujitsu Siemens Esprimo E5600, mainboard D2264-A1, CPU AMD Sempron 3000+. There is a on-board graphics thingy, but I'm not using that; instead I put in a Sapphire Radeon HD 4350 card.
I went over this code change repeatedly but I could not see anything directly that would explain it. However, this patch DOES change the way allocations are placed (while still respecting zone specifiers like __GFP_DMA etc.) and so it's possible that they unearthed a corruption, or a wrongly set dma mask in the drivers.
Ccing the radeon driver guys. Full quote follows.
Can we get a full dmesg, to know if thing like IOMMU are enabled or not. This is even more puzzling as rv710 has 40bit dma mask iirc and thus you should be fine even without IOMMU. But given the patch you point to, it really can only be something that allocate page in place the GPU fails to access.
Thomas how much memory do you have (again dmes will also provide mapping informations) ?
My guess is that the pcie bridge can only remap dma page with 32bit dma mask while the gpu is fine with 40bit dma mask. I always thought that the pcie/pci code did take care of such thing for us.
Cheers, Jérôme Glisse

This patch, adding NR_ALLOC_BATCH, eventually landed in mainline as commit 81c0a2bb515fd4daae8cab64352877480792b515 (2013-09-11).
I recently upgraded a Debian testing system from a 3.11 kernel to 3.12, and it started to exhibit "strange" issues, which I then bisected to this patch. I'm not saying that the patch is faulty, as it seems to be working fine for everyone else, so I rather assume that something in a (vastly?) different corner of the kernel (or my hardware?) is broken. ;-)
The issue is that when X.org/lightdm starts up, there are "garbled" section on the screen, for example, rectangular boxes that are just black or otherwise "distorted", and/or sets of glyphs (corresponding to a set of characters; but not all characters) are displayed as rectangular gray or black boxes, and/or icons in a GNOME session are not displayed properly, and so on. (Can take a snapshot if that helps?) Switching to a Linux console, I can use that one fine. Switching back to X, in the majority of all cases, the screen will be completely black, but with the mouse cursor still rendered properly (done in hardware, I assume).
Reverting commit 81c0a2bb515fd4daae8cab64352877480792b515, for example on top of v3.12, and everything is back to normal. The problem also persists with a v3.14 kernel that I just built.
I will try to figure out what's going on, but will gladly take any pointers, or suggestions about how to tackle such a problem.
The hardware is a Fujitsu Siemens Esprimo E5600, mainboard D2264-A1, CPU AMD Sempron 3000+. There is a on-board graphics thingy, but I'm not using that; instead I put in a Sapphire Radeon HD 4350 card.
I went over this code change repeatedly but I could not see anything directly that would explain it. However, this patch DOES change the way allocations are placed (while still respecting zone specifiers like __GFP_DMA etc.) and so it's possible that they unearthed a corruption, or a wrongly set dma mask in the drivers.
Ccing the radeon driver guys. Full quote follows.
Can we get a full dmesg, to know if thing like IOMMU are enabled or not. This is even more puzzling as rv710 has 40bit dma mask iirc and thus you should be fine even without IOMMU. But given the patch you point to, it really can only be something that allocate page in place the GPU fails to access.
Thomas how much memory do you have (again dmes will also provide mapping informations) ?
My guess is that the pcie bridge can only remap dma page with 32bit dma mask while the gpu is fine with 40bit dma mask. I always thought that the pcie/pci code did take care of such thing for us.
Cheers, Jérôme Glisse
Forgot to attach patch to test my theory. Does the attached patch fix the issue ?

This patch, adding NR_ALLOC_BATCH, eventually landed in mainline as commit 81c0a2bb515fd4daae8cab64352877480792b515 (2013-09-11).
I recently upgraded a Debian testing system from a 3.11 kernel to 3.12, and it started to exhibit "strange" issues, which I then bisected to this patch. I'm not saying that the patch is faulty, as it seems to be working fine for everyone else, so I rather assume that something in a (vastly?) different corner of the kernel (or my hardware?) is broken. ;-)
The issue is that when X.org/lightdm starts up, there are "garbled" section on the screen, for example, rectangular boxes that are just black or otherwise "distorted", and/or sets of glyphs (corresponding to a set of characters; but not all characters) are displayed as rectangular gray or black boxes, and/or icons in a GNOME session are not displayed properly, and so on. (Can take a snapshot if that helps?) Switching to a Linux console, I can use that one fine. Switching back to X, in the majority of all cases, the screen will be completely black, but with the mouse cursor still rendered properly (done in hardware, I assume).
Reverting commit 81c0a2bb515fd4daae8cab64352877480792b515, for example on top of v3.12, and everything is back to normal. The problem also persists with a v3.14 kernel that I just built.
I will try to figure out what's going on, but will gladly take any pointers, or suggestions about how to tackle such a problem.
The hardware is a Fujitsu Siemens Esprimo E5600, mainboard D2264-A1, CPU AMD Sempron 3000+. There is a on-board graphics thingy, but I'm not using that; instead I put in a Sapphire Radeon HD 4350 card.
I went over this code change repeatedly but I could not see anything directly that would explain it. However, this patch DOES change the way allocations are placed (while still respecting zone specifiers like __GFP_DMA etc.) and so it's possible that they unearthed a corruption, or a wrongly set dma mask in the drivers.
Ccing the radeon driver guys. Full quote follows.
Can we get a full dmesg, to know if thing like IOMMU are enabled or not. This is even more puzzling as rv710 has 40bit dma mask iirc and thus you should be fine even without IOMMU. But given the patch you point to, it really can only be something that allocate page in place the GPU fails to access.
Thomas how much memory do you have (again dmes will also provide mapping informations) ?
My guess is that the pcie bridge can only remap dma page with 32bit dma mask while the gpu is fine with 40bit dma mask. I always thought that the pcie/pci code did take care of such thing for us.
Cheers, Jérôme Glisse
Forgot to attach patch to test my theory. Does the attached patch fix the issue ?
So this is likely it, the SIS chipset of this motherboard is a freak show. It support both PCIE and AGP at same time
http://www.newegg.com/Product/Product.aspx?Item=N82E16813185068
Why in hell ?
So my guess is that the root pcie bridge is behind the AGP bridge which swallow any address > 32bit and thus the dma mask of the pcie radeon card is just believing that we are living in a sane world.
Cheers, Jérôme Glisse

This patch, adding NR_ALLOC_BATCH, eventually landed in mainline as commit 81c0a2bb515fd4daae8cab64352877480792b515 (2013-09-11).
I recently upgraded a Debian testing system from a 3.11 kernel to 3.12, and it started to exhibit "strange" issues, which I then bisected to this patch. I'm not saying that the patch is faulty, as it seems to be working fine for everyone else, so I rather assume that something in a (vastly?) different corner of the kernel (or my hardware?) is broken. ;-)
The issue is that when X.org/lightdm starts up, there are "garbled" section on the screen, for example, rectangular boxes that are just black or otherwise "distorted", and/or sets of glyphs (corresponding to a set of characters; but not all characters) are displayed as rectangular gray or black boxes, and/or icons in a GNOME session are not displayed properly, and so on. (Can take a snapshot if that helps?) Switching to a Linux console, I can use that one fine. Switching back to X, in the majority of all cases, the screen will be completely black, but with the mouse cursor still rendered properly (done in hardware, I assume).
Reverting commit 81c0a2bb515fd4daae8cab64352877480792b515, for example on top of v3.12, and everything is back to normal. The problem also persists with a v3.14 kernel that I just built.
I will try to figure out what's going on, but will gladly take any pointers, or suggestions about how to tackle such a problem.
The hardware is a Fujitsu Siemens Esprimo E5600, mainboard D2264-A1, CPU AMD Sempron 3000+. There is a on-board graphics thingy, but I'm not using that; instead I put in a Sapphire Radeon HD 4350 card.
I went over this code change repeatedly but I could not see anything directly that would explain it. However, this patch DOES change the way allocations are placed (while still respecting zone specifiers like __GFP_DMA etc.) and so it's possible that they unearthed a corruption, or a wrongly set dma mask in the drivers.
OK, that was my impression too from reading the patch -- though, in contrast to you, I'm not familiar with this Linux kernel code, so might easily miss some "details". ;-)
Can we get a full dmesg, to know if thing like IOMMU are enabled or not.
Attached dmesg-v3.12 and dmesg-v3.14.
This is even more puzzling as rv710 has 40bit dma mask iirc and thus you should be fine even without IOMMU. But given the patch you point to, it really can only be something that allocate page in place the GPU fails to access.
Thomas how much memory do you have (again dmes will also provide mapping informations) ?
4 GiB; see dmesg.
My guess is that the pcie bridge can only remap dma page with 32bit dma mask while the gpu is fine with 40bit dma mask. I always thought that the pcie/pci code did take care of such thing for us.
Forgot to attach patch to test my theory. Does the attached patch fix the issue ?
Unfortunately it does not. :-/
So this is likely it, the SIS chipset of this motherboard is a freak show.
Well, it has been a freak show before: system crash if I put into the CD drive a specific audio CD: http://news.gmane.org/find-root.php?message_id=%3C87obojef7t.fsf%40schwinge.name%3E. (This issue remains unresolved, unless it has "fixed itself" -- I have not recently tried what happens now.)
It support both PCIE and AGP at same time
http://www.newegg.com/Product/Product.aspx?Item=N82E16813185068
Why in hell ?
So my guess is that the root pcie bridge is behind the AGP bridge which swallow any address > 32bit and thus the dma mask of the pcie radeon card is just believing that we are living in a sane world.

This patch, adding NR_ALLOC_BATCH, eventually landed in mainline as commit 81c0a2bb515fd4daae8cab64352877480792b515 (2013-09-11).
I recently upgraded a Debian testing system from a 3.11 kernel to 3.12, and it started to exhibit "strange" issues, which I then bisected to this patch. I'm not saying that the patch is faulty, as it seems to be working fine for everyone else, so I rather assume that something in a (vastly?) different corner of the kernel (or my hardware?) is broken. ;-)
The issue is that when X.org/lightdm starts up, there are "garbled" section on the screen, for example, rectangular boxes that are just black or otherwise "distorted", and/or sets of glyphs (corresponding to a set of characters; but not all characters) are displayed as rectangular gray or black boxes, and/or icons in a GNOME session are not displayed properly, and so on. (Can take a snapshot if that helps?) Switching to a Linux console, I can use that one fine. Switching back to X, in the majority of all cases, the screen will be completely black, but with the mouse cursor still rendered properly (done in hardware, I assume).
Reverting commit 81c0a2bb515fd4daae8cab64352877480792b515, for example on top of v3.12, and everything is back to normal. The problem also persists with a v3.14 kernel that I just built.
My guess is that the pcie bridge can only remap dma page with 32bit dma mask while the gpu is fine with 40bit dma mask. I always thought that the pcie/pci code did take care of such thing for us.
Forgot to attach patch to test my theory. Does the attached patch fix the issue ?
Unfortunately it does not. :-/
Ha, the following seems to do it: additionally to dma_bits (your patch), I'm also overriding need_dma32 for later use in drivers/gpu/drm/ttm/ttm_bo.c:ttm_bo_add_ttm, I assume. With that hack applied, I have now rebooted a v3.14 build a few times, and so far things "look" fine.

I will try to figure out what's going on, but will gladly take any pointers, or suggestions about how to tackle such a problem.
The hardware is a Fujitsu Siemens Esprimo E5600, mainboard D2264-A1, CPU AMD Sempron 3000+. There is a on-board graphics thingy, but I'm not using that; instead I put in a Sapphire Radeon HD 4350 card.
I went over this code change repeatedly but I could not see anything directly that would explain it. However, this patch DOES change the way allocations are placed (while still respecting zone specifiers like __GFP_DMA etc.) and so it's possible that they unearthed a corruption, or a wrongly set dma mask in the drivers.
Ccing the radeon driver guys. Full quote follows.

Thomas can you provide output of lspci -t
Also did you had a chance to test my ugly patch ?

This patch, adding NR_ALLOC_BATCH, eventually landed in mainline as commit 81c0a2bb515fd4daae8cab64352877480792b515 (2013-09-11).
I recently upgraded a Debian testing system from a 3.11 kernel to 3.12, and it started to exhibit "strange" issues, which I then bisected to this patch. I'm not saying that the patch is faulty, as it seems to be working fine for everyone else, so I rather assume that something in a (vastly?) different corner of the kernel (or my hardware?) is broken. ;-)
The issue is that when X.org/lightdm starts up, there are "garbled" section on the screen, for example, rectangular boxes that are just black or otherwise "distorted", and/or sets of glyphs (corresponding to a set of characters; but not all characters) are displayed as rectangular gray or black boxes, and/or icons in a GNOME session are not displayed properly, and so on. (Can take a snapshot if that helps?) Switching to a Linux console, I can use that one fine. Switching back to X, in the majority of all cases, the screen will be completely black, but with the mouse cursor still rendered properly (done in hardware, I assume).
Reverting commit 81c0a2bb515fd4daae8cab64352877480792b515, for example on top of v3.12, and everything is back to normal. The problem also persists with a v3.14 kernel that I just built.
I will try to figure out what's going on, but will gladly take any pointers, or suggestions about how to tackle such a problem.
The hardware is a Fujitsu Siemens Esprimo E5600, mainboard D2264-A1, CPU AMD Sempron 3000+. There is a on-board graphics thingy, but I'm not using that; instead I put in a Sapphire Radeon HD 4350 card.
I went over this code change repeatedly but I could not see anything directly that would explain it. However, this patch DOES change the way allocations are placed (while still respecting zone specifiers like __GFP_DMA etc.) and so it's possible that they unearthed a corruption, or a wrongly set dma mask in the drivers.

Thomas can you provide output of lspci -t
Also did you had a chance to test my ugly patch ?
Cheers, Jérôme
If my ugly patch works does this quirk also work ?
- /* We are living in a monstruous world in which you can have the pci
* root complex behind an hypertransport link which can not address* anything above 32bit (well hypertransport specification says 40bits* but hardware such as SIS761 only support 32bits).
That looks more like a problem with this specific chipset rather than something that needs a general solution like this.
Maybe we should rather add the PCI-ID(s) of the thing to some kind of quirks table for now so that the patch isn't so invasive and we can CC stable as well?
Just a thought, Christian.

This patch, adding NR_ALLOC_BATCH, eventually landed in mainline as commit 81c0a2bb515fd4daae8cab64352877480792b515 (2013-09-11).
I recently upgraded a Debian testing system from a 3.11 kernel to 3.12, and it started to exhibit "strange" issues, which I then bisected to this patch. I'm not saying that the patch is faulty, as it seems to be working fine for everyone else, so I rather assume that something in a (vastly?) different corner of the kernel (or my hardware?) is broken. ;-)
The issue is that when X.org/lightdm starts up, there are "garbled" section on the screen, for example, rectangular boxes that are just black or otherwise "distorted", and/or sets of glyphs (corresponding to a set of characters; but not all characters) are displayed as rectangular gray or black boxes, and/or icons in a GNOME session are not displayed properly, and so on. (Can take a snapshot if that helps?) Switching to a Linux console, I can use that one fine. Switching back to X, in the majority of all cases, the screen will be completely black, but with the mouse cursor still rendered properly (done in hardware, I assume).
Reverting commit 81c0a2bb515fd4daae8cab64352877480792b515, for example on top of v3.12, and everything is back to normal. The problem also persists with a v3.14 kernel that I just built.
I will try to figure out what's going on, but will gladly take any pointers, or suggestions about how to tackle such a problem.
The hardware is a Fujitsu Siemens Esprimo E5600, mainboard D2264-A1, CPU AMD Sempron 3000+. There is a on-board graphics thingy, but I'm not using that; instead I put in a Sapphire Radeon HD 4350 card.
I went over this code change repeatedly but I could not see anything directly that would explain it. However, this patch DOES change the way allocations are placed (while still respecting zone specifiers like __GFP_DMA etc.) and so it's possible that they unearthed a corruption, or a wrongly set dma mask in the drivers.
Ccing the radeon driver guys. Full quote follows.

Thomas can you provide output of lspci -t
Also did you had a chance to test my ugly patch ?
Cheers, Jérôme
If my ugly patch works does this quirk also work ?

Maybe we should rather add the PCI-ID(s) of the thing to some kind of quirks table for now so that the patch isn't so invasive and we can CC stable as well?
IIRC, there was someone on IRC with a similar problem with a similar SiS chipset a while back. These SiS chipsets seem to be generally problematic.

Just a thought, Christian.

This patch, adding NR_ALLOC_BATCH, eventually landed in mainline as commit 81c0a2bb515fd4daae8cab64352877480792b515 (2013-09-11).
I recently upgraded a Debian testing system from a 3.11 kernel to 3.12, and it started to exhibit "strange" issues, which I then bisected to this patch. I'm not saying that the patch is faulty, as it seems to be working fine for everyone else, so I rather assume that something in a (vastly?) different corner of the kernel (or my hardware?) is broken. ;-)
The issue is that when X.org/lightdm starts up, there are "garbled" section on the screen, for example, rectangular boxes that are just
black
or otherwise "distorted", and/or sets of glyphs (corresponding to a set of characters; but not all characters) are displayed as rectangular gray or black boxes, and/or icons in a GNOME session are not displayed properly, and so on. (Can take a snapshot if that helps?) Switching to a Linux console, I can use that one fine. Switching back to X, in the majority of all cases, the screen will be completely black, but with the mouse cursor still rendered properly (done in hardware, I assume).
Reverting commit 81c0a2bb515fd4daae8cab64352877480792b515, for
example on
top of v3.12, and everything is back to normal. The problem also persists with a v3.14 kernel that I just built.
I will try to figure out what's going on, but will gladly take any pointers, or suggestions about how to tackle such a problem.
The hardware is a Fujitsu Siemens Esprimo E5600, mainboard D2264-A1,
CPU
AMD Sempron 3000+. There is a on-board graphics thingy, but I'm not using that; instead I put in a Sapphire Radeon HD 4350 card.
I went over this code change repeatedly but I could not see anything directly that would explain it. However, this patch DOES change the way allocations are placed (while still respecting zone specifiers like __GFP_DMA etc.) and so it's possible that they unearthed a corruption, or a wrongly set dma mask in the drivers.
Ccing the radeon driver guys. Full quote follows.

Thomas can you provide output of lspci -t
Also did you had a chance to test my ugly patch ?
Cheers, Jérôme
If my ugly patch works does this quirk also work ?

- /* We are living in a monstruous world in which you can have the pci
* root complex behind an hypertransport link which can not address* anything above 32bit (well hypertransport specification says 40bits* but hardware such as SIS761 only support 32bits).That looks more like a problem with this specific chipset rather than something that needs a general solution like this.
Maybe we should rather add the PCI-ID(s) of the thing to some kind of quirks table for now so that the patch isn't so invasive and we can CC stable as well?
IIRC, there was someone on IRC with a similar problem with a similar SiS chipset a while back. These SiS chipsets seem to be generally problematic.
IIRC, in the IRC case, the fix was to limit the about of physical memory in the system.

Just a thought, Christian.

commit 81c0a2bb515fd4daae8cab64352877480792b515 (2013-09-11).
I recently upgraded a Debian testing system from a 3.11 kernel to
3.12,
and it started to exhibit "strange" issues, which I then bisected to this patch. I'm not saying that the patch is faulty, as it seems to be working fine for everyone else, so I rather assume that something in
a
(vastly?) different corner of the kernel (or my hardware?) is broken. ;-)
The issue is that when X.org/lightdm starts up, there are "garbled" section on the screen, for example, rectangular boxes that are just
black
or otherwise "distorted", and/or sets of glyphs (corresponding to a
set
of characters; but not all characters) are displayed as rectangular gray or black boxes, and/or icons in a GNOME session are not displayed properly, and so on. (Can take a snapshot if that helps?) Switching to a Linux console, I can use that one fine. Switching back to X, in the majority of all cases, the screen will be completely black, but with the mouse cursor still rendered properly (done in hardware, I assume).
Reverting commit 81c0a2bb515fd4daae8cab64352877480792b515, for
example on
top of v3.12, and everything is back to normal. The problem also persists with a v3.14 kernel that I just built.
I will try to figure out what's going on, but will gladly take any pointers, or suggestions about how to tackle such a problem.
The hardware is a Fujitsu Siemens Esprimo E5600, mainboard D2264-
A1,
CPU
AMD Sempron 3000+. There is a on-board graphics thingy, but I'm
not
using that; instead I put in a Sapphire Radeon HD 4350 card.
I went over this code change repeatedly but I could not see anything directly that would explain it. However, this patch DOES change the way allocations are placed (while still respecting zone specifiers like __GFP_DMA etc.) and so it's possible that they unearthed a corruption, or a wrongly set dma mask in the drivers.
Ccing the radeon driver guys. Full quote follows.

Thomas can you provide output of lspci -t
Also did you had a chance to test my ugly patch ?
Cheers, Jérôme
If my ugly patch works does this quirk also work ?
Hi!

Unfortunately they both don't; see my other email, http://news.gmane.org/find-root.php?message_id=%3C87sioxq3rx.fsf%40schwinge.name%3E.
Also, the quirk patch resulted in a NULL pointer dereference in pci_find_ht_capability+0x4/0x30, which I hacked around as follows:

If needed, I can try to capture more data, but someone who has knowledge of PCI bus architecture and Linux kernel code (so, not me), might probably already see what's wrong.

The problem "solved itself": the machine recently died of hardware failure. ;-|
