https://bugs.freedesktop.org/show_bug.cgi?id=27609 Summary: Regression: r600 CS checker rejects narrow FBO renderbuffers. Product: DRI Version: unspecified Platform: Other OS/Version: All Status: NEW Severity: major Priority: medium Component: DRM/Radeon AssignedTo: dri-devel(a)lists.freedesktop.org ReportedBy: nbowler(a)draconx.ca Created an attachment (id=34944) --> (https://bugs.freedesktop.org/attachment.cgi?id=34944) Full kernel log including failure message. The R600 CS checker recently merged into the mainline kernel breaks rendering to FBOs with renderbuffers of width <= 48. The height does not matter. Attempting to run such a program terminates with drmRadeonCmdBuffer: -22. Kernel failed to parse or rejected command stream. See dmesg for more info. and in dmesg: radeon 0000:03:00.0: r600_cs_track_validate_cb:198 cb pitch (32 x 4 = 128) invalid radeon 0000:03:00.0: r600_packet3_check:1109 invalid cmd stream 514 [drm:radeon_cs_ioctl] *ERROR* Invalid command stream ! Please see the test case attached to bug 27590 for a program which triggers this issue. The program works on Linux 2.6.33 and with the software rasterizer. The problem is reproducible with both mesa 7.8.1 and git master, against latest Linus git kernel. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

[Bug 88921] X fails to start on QEMU/KVM with cirrus KMS since 3.19-rc

https://bugs.freedesktop.org/show_bug.cgi?id=88921 Bug ID: 88921 Summary: X fails to start on QEMU/KVM with cirrus KMS since 3.19-rc Product: DRI Version: unspecified Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/other Assignee: dri-devel(a)lists.freedesktop.org Reporter: tiwai(a)suse.de X modesetting driver fails to start with cirrus KMS on QEMU/KVM since 3.19-rc. The culprit is the commit 8975626ea35adcca561f8a81dedccfbc5dd8ec72 drm/cirrus: allow 32bpp framebuffers for cirrus drm Reverting this commit makes X working again. X modesetting driver seems to try to open 1024x768x32 graphics, where the pitch is 4096 and greater than max_pitch (4088) defined in cirrus_check_framebuffer(). And it doesn't fall back to 24bpp as the patch expected. Tested with 3.19-rc7 with qemu 2.1 -vga cirrus option. -- You are receiving this mail because: You are the assignee for the bug.

[Bug 71083] New: (struct drm_encoder_helper_funcs)->mode_set not re-called after display (and EDID) change

https://bugs.freedesktop.org/show_bug.cgi?id=71083 Priority: medium Bug ID: 71083 Assignee: dri-devel(a)lists.freedesktop.org Summary: (struct drm_encoder_helper_funcs)->mode_set not re-called after display (and EDID) change Severity: normal Classification: Unclassified OS: All Reporter: zajec5(a)gmail.com Hardware: Other Status: NEW Version: unspecified Component: DRM/other Product: DRI I use my DCE5 Barts (HD69xx) with AV-receiver Onkyo TX-SR605 and one of the following displays: 1) TV Sony Bravia KDL-52X3500 2) Projector Epson EH-TW6100 My problem is that when I change display connected to the Onkyo's output EDID changes, but drm doesn't call mode_set as long as I use the same resolution. To force drm to call mode_set I've to change resolution (xrandr --output HDMI-0 --mode X) and then swtich back to the mode I want. While the display seems to be working fine without that mode_set call, the audio engine doesn't. As part of the modesetting handler we read ELD-related info from EDID and write it to the audio engine of the GPU. Without this happening I can't play correctly audio (because also sees info about previous device, not the current one). I think mode_set should be called every time EDID changes. Is that right? In case someone's curious: 1) EDID with Onkyo + Sony TV: 00ffffffffffff003dcb610700000000 0011010380a05a780a0dc9a057479827 12484c21080081800101010101010101 010101010101023a801871382d40582c 450040846300001e011d007251d01e20 6e28550040846300001e000000fc0054 582d53523630350a20202020000000fd 00303e0e460f000a2020202020200185 02034c705c1f03041213051420071610 15110206010f1e0b1a191d0e0a242625 2335097f070f7f071707503f06c05706 005f7e01671e00834f00006c030c0012 00b82dc000000000e3050301023a80d0 72382d40102c458040846300001e011d 00bc52d01e20b828554040846300001e 00000000000000000000000000000078 2) EDID with Onkyo + Epson projector: 00ffffffffffff004ca333d000000000 0c150104952616780aa0558d515a962a 1c505400000001010101010101010101 0101010101016a4d80a07038fc413020 36007ed710000018d49a80a07038fc41 302036007ed710000038000000fc0053 414d53554e470a2020202020000000fc 00313733485430322d4330310a200035 -- You are receiving this mail because: You are the assignee for the bug.

Instead it is commit e6e792092e816bea0797995c886fb057c91d4546 that breaks things. With 3.10 I have just this 24p mode in Xorg: [ 47.361] (II) RADEON(0): Modeline "1920x1080"x24.0 74.25 1920 2558 2602 2750 1080 1084 1089 1125 +hsync +vsync (27.0 kHz e) With 3.11 I have two: Xorg.0.log:[ 56.189] (II) RADEON(0): Modeline "1920x1080"x24.0 74.25 1920 2558 2602 2750 1080 1084 1089 1125 +hsync +vsync (27.0 kHz e) Xorg.0.log:[ 56.189] (II) RADEON(0): Modeline "1920x1080"x24.0 74.18 1920 2558 2602 2750 1080 1084 1089 1125 +hsync +vsync (27.0 kHz e) And although the second one gives me an image, audio is royally screwed up.

[Bug 80628] New: The way KMS works doesn't support HDMI/DP well

https://bugs.freedesktop.org/show_bug.cgi?id=80628 Priority: medium Bug ID: 80628 Assignee: dri-devel(a)lists.freedesktop.org Summary: The way KMS works doesn't support HDMI/DP well Severity: enhancement Classification: Unclassified OS: Linux (All) Reporter: tom.ty89(a)gmail.com Hardware: Other Status: NEW Version: XOrg CVS Component: DRM/other Product: DRI If the machine has no monitor attached at all before boot, KMS couldn't probe the monitor and make it goes into native resolution afterwards. This issue is not very obvious when DVI/VGA are the only connectors available because of their mechanism. When it comes to HDMI/DP, the monitor is considered disconnected when it's powered off. Then the issue become annoying, while we have to make sure that one monitor is connected and switched on before boot. Moreover, display managers have to be started manually under such situation after you turn on your monitor. Not even all DM can start X in optimal resolution without some "xrandr hack" By the way, it's funny that if you got one attached, you can power on others later without getting into the problem. Just that I am not sure if it's because all my monitors have the same optimal resolution. -- You are receiving this mail because: You are the assignee for the bug.

Asked about this security problem in #gentoo-hardened, #radeon and #dri-devel, summarizing: 0) Currently GPU memory is not sanitized by kernel, nothing enforces and ensures its sanitizing. 1) https://grsecurity.net Linux kernel patches add ability to sanitize all freed memory, but they do not affect GPU memory: https://en.wikibooks.org/wiki/Grsecurity/Appendix/Grsecurity_and_PaX_Config… 2) The only secure place to clean memory is kernel, because if application or X server crashes, memory will not be erased. 3) Some applications possibly will work slower, so better make sanitizing configurable by adding build and run time kernel options. 4) Most likely this problem affects opencl too. -- You are receiving this mail because: You are the assignee for the bug.
