Just a dumb question, but why is *all* memory in the linear map on arm64? It would seem useful to have a source of pages that is not in the linear map. I guess it is mapped as huge pages (or something larger than 4k pages)? Any recommended reading to understand how/why the kernel address space is setup the way it is (so I can ask fewer dumb questions)? BR, -R

Currently we use WC for basically all GEM buffers allocated from kernel, since that is a good choice for most GPU workloads.. ie. CPU isn't reading back from GPU buffers in most cases. I'm told cached buffers are useful for compute workloads where there is more back and forth between GPU and CPU, but we haven't really crossed that bridge yet. Compute workloads is also were the SVM interest is. > > > So back to the question, I'd like to understand your use case (and > > > maybe hear from the other drm folks if that is common): > > > > > > - you allocate pages from shmem (why shmem, btw? if this is done by > > > other drm drivers how do they guarantee addressability without an > > > iommu?) > > > > shmem for swappable pages.

[PATCH] drm/virtio: use virtio_max_dma_size

[PULL] drm-misc-next

Hi Daniel, Dave, Here is the first (and pretty late) drm-misc-next PR. It's pretty big due to the lateness, but there's nothing really major showing up. It's pretty much the usual bunch of reworks, fixes, and new helpers being introduced. Thanks!

[Bug 110214] amdgpu: xterm scrollback buffer disappears while paging up/down
by bugzilla-daemon＠freedesktop.org 08 Aug '19

08 Aug '19

https://bugs.freedesktop.org/show_bug.cgi?id=110214 Bug ID: 110214 Summary: amdgpu: xterm scrollback buffer disappears while paging up/down Product: DRI Version: XOrg git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel(a)lists.freedesktop.org Reporter: diego.viola(a)gmail.com Whenever I run `dmesg' on a xterm that uses the following options: xterm -fa "DejaVu Sans Mono:style=Book:antialias=true" -fs 9 and I scroll up with the keyboard (shift+page up) parts of the scrollback buffer disappears, making it difficult to read the output. I've tested other terminals (urxvt and alacritty) and I cannot trigger the bug with these terminals, with xterm it happens only with xft and with the options I mentioned above. Steps to reproduce: - run `xterm -fa "DejaVu Sans Mono:style=Book:antialias=true" -fs 9' - run `dmesg', hit enter and page up You should notice parts of the buffer disappearing. I use the modesetting DDX driver, I also tried the xf86-video-amdgpu DDX driver and I can reproduce it with both, however, when setting Option "Accel" "off" in /etc/X11/xorg.conf.d/20-amdgpu.conf I cannot reproduce it anymore. Actual Results: As mentioned, the scrollback buffer disappears when paging up with these xterm options that I mentioned above. Expected Results: xterm works normally with these options, with no scrollback buffer issues. System details: - Arch Linux (x86_64) - linux 5.0.2-arch1-1-ARCH - xorg-server 1.20.4-1 - i3-wm 4.16.1-1 - xterm 344-1 - mesa 19.0.0-1 My machine is a "AMD Ryzen 5 2400G with Radeon Vega Graphics" APU with integrated vega graphics. $ lspci | grep VGA 07:00.0 VGA compatible controller: Advanced Micro Devices, Inc.

[PATCH v3 0/8] drm/panfrost: Add heap and no execute buffer allocation
by Rob Herring 08 Aug '19

08 Aug '19

This series adds new BO allocation flags PANFROST_BO_HEAP and PANFROST_BO_NOEXEC. The heap allocations are paged in on GPU page faults. Tomeu reports he has tested this in the panfrost CI. This is based on drm-misc-next. An updated branch is here[1]. v3: - Retain shared irq support, splitting IRQ changes to separate patch (6/8) - Stop leaking SG tables - Prevent mmap and pinning pages for heap BOs Rob [1] git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux.git panfrost/heap-noexec Rob Herring (8): drm/gem: Allow sparsely populated page arrays in drm_gem_put_pages drm/shmem: Put pages independent of a SG table being set drm/panfrost: Restructure the GEM object creation drm/panfrost: Split panfrost_mmu_map SG list mapping to its own function drm/panfrost: Add a no execute flag for BO allocations drm/panfrost: Convert MMU IRQ handler to threaded handler drm/panfrost: Add support for GPU heap allocations drm/panfrost: Bump driver version to 1.1 drivers/gpu/drm/drm_gem.c | 3 + drivers/gpu/drm/drm_gem_shmem_helper.c | 4 +- drivers/gpu/drm/panfrost/TODO | 2 - drivers/gpu/drm/panfrost/panfrost_drv.c | 65 ++++++-- drivers/gpu/drm/panfrost/panfrost_gem.c | 106 +++++++++++-- drivers/gpu/drm/panfrost/panfrost_gem.h | 16 +- drivers/gpu/drm/panfrost/panfrost_mmu.c | 200 ++++++++++++++++++++---- include/uapi/drm/panfrost_drm.h | 3 + 8 files changed, 333 insertions(+), 66 deletions(-) -- 2.20.1

To summarize the exynos-bus topology[1] used by the devfreq driver: There are many data buses for data transfer in Samsung Exynos SoC. Every bus has its own clock. Buses often share power lines, in which case one of the buses on the power line is referred to as 'parent' (or as 'devfreq' in the DT). In the particular case of Exynos4412[1][2], the topology can be expressed as follows: bus_dmc -- bus_acp -- bus_c2c bus_leftbus -- bus_rightbus -- bus_display -- bus_fsys -- bus_peri -- bus_mfc Where bus_dmc and bus_leftbus probably could be referred to as masters, and the following indented nodes as slaves. Patch 08/11 of this RFC additionally adds the following to the DT: bus_dmc -- bus_leftbus Which makes the topology a valid tree. The exynos-bus concept in devfreq[3] is designed in such a way that every bus is probed separately as a platform device, and is a largely independent entity. This RFC proposes an extension to the existing devfreq driver that basically provides a simple QoS to ensure minimum clock frequency for selected buses (possibly overriding devfreq governor calculations) using the interconnect framework. The hierarchy is modelled in such a way that every bus is an interconnect node. On the other hand, what is considered an interconnect provider here is quite arbitrary, but for the reasons mentioned in the above paragraph, this RFC assumes that every bus is a provider of itself as a node. Using an alternative singleton provider approach was deemed more complicated since the 'dev' field in 'struct icc_provider' has to be set to something meaningful and we are tied to the 'samsung,exynos-bus' compatible string in the driver (and multiple instances of exynos-bus probed in indeterminate relative order). I'm looking forward to hearing any additional thoughts you may have on this topic.
