[RFC][PATCH v6 0/7] Generic page pool & deferred freeing for system dmabuf heap
by John Stultz 10 Feb '21

10 Feb '21

This series is starting to get long, so I figured I'd add a short cover letter for context. The point of this series is trying to add both deferred-freeing logic as well as a page pool to the DMA-BUF system heap. This is desired, as the combination of deferred freeing along with the page pool allows us to offload page-zeroing out of the allocation hot path. This was done originally with ION and this patch series allows the DMA-BUF system heap to match ION's system heap allocation performance in a simple microbenchmark [1] (ION re-added to the kernel for comparision, running on an x86 vm image): ./dmabuf-heap-bench -i 0 1 system Testing dmabuf system vs ion heaptype 0 (flags: 0x1) --------------------------------------------- dmabuf heap: alloc 4096 bytes 5000 times in 86572223 ns 17314 ns/call ion heap: alloc 4096 bytes 5000 times in 97442526 ns 19488 ns/call dmabuf heap: alloc 1048576 bytes 5000 times in 196635057 ns 39327 ns/call ion heap: alloc 1048576 bytes 5000 times in 357323629 ns 71464 ns/call dmabuf heap: alloc 8388608 bytes 5000 times in 3165445534 ns 633089 ns/call ion heap: alloc 8388608 bytes 5000 times in 3699591271 ns 739918 ns/call dmabuf heap: alloc 33554432 bytes 5000 times in 13327402517 ns 2665480 ns/call ion heap: alloc 33554432 bytes 5000 times in 15292352796 ns 3058470 ns/call Daniel didn't like earlier attempts to re-use the network page-pool code to achieve this, and suggested the ttm_pool be used instead. This required pulling the fairly tightly knit ttm_pool logic apart, but after many failed attmempts I think I found a workable abstraction to split out shared logic. So this series contains a new generic drm_page_pool helper library, converts the ttm_pool to use it, and then adds the dmabuf deferred freeing and adds support to the dmabuf system heap to use both deferred freeing and the new drm_page_pool. Input would be greatly appreciated. Testing as well, as I don't have any development hardware that utilizes the ttm pool. thanks -john [1] https://android.googlesource.com/platform/system/memory/libdmabufheap/+/ref… Cc: Daniel Vetter <daniel(a)ffwll.ch> Cc: Christian Koenig <christian.koenig(a)amd.com> Cc: Sumit Semwal <sumit.semwal(a)linaro.org> Cc: Liam Mark <lmark(a)codeaurora.org> Cc: Chris Goldsworthy <cgoldswo(a)codeaurora.org> Cc: Laura Abbott <labbott(a)kernel.org> Cc: Brian Starkey <Brian.Starkey(a)arm.com> Cc: Hridya Valsaraju <hridya(a)google.com> Cc: Suren Baghdasaryan <surenb(a)google.com> Cc: Sandeep Patil <sspatil(a)google.com> Cc: Daniel Mentz <danielmentz(a)google.com> Cc: Ørjan Eide <orjan.eide(a)arm.com> Cc: Robin Murphy <robin.murphy(a)arm.com> Cc: Ezequiel Garcia <ezequiel(a)collabora.com> Cc: Simon Ser <contact(a)emersion.fr> Cc: James Jones <jajones(a)nvidia.com> Cc: linux-media(a)vger.kernel.org Cc: dri-devel(a)lists.freedesktop.org John Stultz (7): drm: Add a sharable drm page-pool implementation drm: ttm_pool: Rename the ttm_pool_dma structure to ttm_pool_page_dat drm: ttm_pool: Rework ttm_pool_free_page to allow us to use it as a function pointer drm: ttm_pool: Rework ttm_pool to use drm_page_pool dma-buf: heaps: Add deferred-free-helper library code dma-buf: system_heap: Add drm pagepool support to system heap dma-buf: system_heap: Add deferred freeing to the system heap drivers/dma-buf/heaps/Kconfig | 5 + drivers/dma-buf/heaps/Makefile | 1 + drivers/dma-buf/heaps/deferred-free-helper.c | 145 ++++++++++ drivers/dma-buf/heaps/deferred-free-helper.h | 55 ++++ drivers/dma-buf/heaps/system_heap.c | 77 ++++- drivers/gpu/drm/Kconfig | 5 + drivers/gpu/drm/Makefile | 1 + drivers/gpu/drm/page_pool.c | 220 +++++++++++++++ drivers/gpu/drm/ttm/ttm_pool.c | 278 ++++++------------- include/drm/page_pool.h | 54 ++++ include/drm/ttm/ttm_pool.h | 23 +- 11 files changed, 639 insertions(+), 225 deletions(-) create mode 100644 drivers/dma-buf/heaps/deferred-free-helper.c create mode 100644 drivers/dma-buf/heaps/deferred-free-helper.h create mode 100644 drivers/gpu/drm/page_pool.c create mode 100644 include/drm/page_pool.h -- 2.25.1

[RFC][PATCH 0/9] drm: Support simple-framebuffer devices and firmware fbs
by Thomas Zimmermann 10 Feb '21

10 Feb '21

This patchset adds support for simple-framebuffer platform devices and a handover mechanism for native drivers to take-over control of the hardware. The new driver, called simplekms, binds to a simple-frambuffer platform device. The kernel's boot code creates such devices for firmware-provided framebuffers, such as EFI-GOP or VESA. Typically the BIOS, UEFI or boot loader sets up the framebuffers. Description via device tree is also an option. Simplekms is small enough to be linked into the kernel. The driver's main purpose is to provide graphical output during the early phases of the boot process, before the native DRM drivers are available. Native drivers are typically loaded from an initrd ram disk. Occationally simplekms can also serve as interim solution on graphics hardware without native DRM driver. So far distributions rely on fbdev drivers, such as efifb, vesafb or simplefb, for early-boot graphical output. However fbdev is deprecated and the drivers do not provide DRM interfaces for modern userspace. Patches 1 and 2 prepare the DRM format helpers for simplekms. Patches 3 to 7 add the simplekms driver. It's build on simple DRM helpers and SHMEM. It supports 16-bit, 24-bit and 32-bit RGB framebuffers. During pageflips, SHMEM buffers are copied into the framebuffer memory, similar to cirrus or mgag200. The code in patches 6 and 7 handles clocks and regulators. It's based on the simplefb drivers, but has been modified for DRM. Patches 8 and 9 add a hand-over mechanism. Simplekms acquires it's framebuffer's I/O-memory range and provides a callback function to be removed by a native driver. The native driver will remove simplekms before taking over the hardware. The removal is integrated into existing helpers, so drivers use it automatically. I tested simplekms with x86 EFI and VESA framebuffers, which both work reliably. The fbdev console and Weston work automatically. Xorg requires manual configuration of the device. Xorgs current modesetting driver does not work with both, platform and PCI device, for the same physical hardware. Once configured, X11 works. One cosmetical issue is that simplekms's device file is card0 and the native driver's device file is card1. After simplekms has been kicked out, only card1 is left. This does not seem to be a practical problem however.

[PATCH] drm/gem: Move drm_gem_fb_prepare_fb() to GEM atomic helpers
by Thomas Zimmermann 10 Feb '21

10 Feb '21

The function drm_gem_fb_prepare_fb() is a helper for atomic modesetting, but currently located next to framebuffer helpers. Move it to GEM atomic helpers, rename it slightly and adopt the drivers. Same for the rsp simple-pipe helper. Compile-tested with x86-64, aarch64 and arm. The patch is fairly large, but there are no functional changes.

[PATCH] drm: use getter/setter functions
by Julia Lawall 10 Feb '21

[PATCH 5.10 078/120] drm/dp/mst: Export drm_dp_get_vc_payload_bw()
by Greg Kroah-Hartman 10 Feb '21

10 Feb '21

From: Imre Deak <imre.deak(a)intel.com> commit 83404d581471775f37f85e5261ec0d09407d8bed upstream. This function will be needed by the next patch where the driver calculates the BW based on driver specific parameters, so export it. At the same time sanitize the function params, passing the more natural link rate instead of the encoding of the same rate. v2: - Fix function documentation.

[PATCH] drm/vblank: Document drm_crtc_vblank_restore constraints
by Daniel Vetter 10 Feb '21

10 Feb '21

I got real badly confused when trying to review a fix from Ville for this. Let's try to document better what's required for this, and check the minimal settings at runtime - we can't check ofc that there's indeed no races in the driver callback. Also noticed that the drm_vblank_restore version is unused, so lets unexport that while at it.
