Hi Dave, Daniel, The following changes since commit 136057256686de39cc3a07c2e39ef6bc43003ff6: Linux 5.16-rc2 (2021-11-21 13:47:39 -0800) are available in the Git repository at: https://gitlab.freedesktop.org/drm/tegra.git tags/drm/tegra/for-5.17-rc1 for you to fetch changes up to d210919dbdc8a82c676cc3e3c370b1802be63124: drm/tegra: Add back arm_iommu_detach_device() (2021-12-16 14:30:45 +0100) This is unusually big because it contains essentially two cycles' worth of work. I'm still not sure what happened for v5.16-rc1, but the PR was never merged. Fingers crossed that it will work better this time. As mentioned last time already, the userspace for the new NVDEC driver can be found here: https://github.com/cyndis/vaapi-tegra-driver Thanks, Thierry ---------------------------------------------------------------- drm/tegra: Changes for v5.17-rc1 This contains a fairly large rework that makes the buffer objects behave more according to what the DMA-BUF infrastructure expects. A buffer object cache is implemented on top of that to make certain operations such as page-flipping more efficient by avoiding needless map/unmap operations. This in turn is useful to implement asynchronous commits to support legacy cursor updates. Another fairly big addition is the NVDEC driver. This uses the updated UABI introduced in v5.15-rc1 to provide access to the video decode engines found on Tegra210 and later. This also includes some power management improvements that are useful on older devices in particular because they, together with a bunch of other changes across the kernel, allow the system to scale down frequency and voltages when mostly idle and prevent these devices from becoming excessively hot. The remainder of these changes is an assortment of cleanups and minor fixes. ---------------------------------------------------------------- Arnd Bergmann (3): gpu: host1x: select CONFIG_DMA_SHARED_BUFFER drm/tegra: Mark nvdec_writel() as inline drm/tegra: Mark nvdec PM functions as __maybe_unused Dmitry Osipenko (19): soc/tegra: Enable runtime PM during OPP state-syncing soc/tegra: Add devm_tegra_core_dev_init_opp_table_common() drm/tegra: dc: rgb: Move PCLK shifter programming to CRTC drm/tegra: dc: rgb: Allow changing PLLD rate on Tegra30+ drm/tegra: hdmi: Unwind tegra_hdmi_init() errors drm/tegra: hdmi: Register audio CODEC on Tegra20 gpu: host1x: Add initial runtime PM and OPP support gpu: host1x: Add host1x_channel_stop() drm/tegra: submit: Add missing pm_runtime_mark_last_busy() drm/tegra: dc: Support OPP and SoC core voltage scaling drm/tegra: hdmi: Add OPP support drm/tegra: gr2d: Support generic power domain and runtime PM drm/tegra: gr3d: Support generic power domain and runtime PM drm/tegra: vic: Stop channel on suspend drm/tegra: nvdec: Stop channel on suspend drm/tegra: submit: Remove pm_runtime_enabled() checks drm/tegra: Consolidate runtime PM management of older UAPI codepath gpu: host1x: Add back arm_iommu_detach_device() drm/tegra: Add back arm_iommu_detach_device() Mikko Perttunen (3): drm/tegra: Add NVDEC driver drm/tegra: Bump VIC/NVDEC clock rates to Fmax drm/tegra: vic: Use autosuspend Randy Dunlap (1): gpu: host1x: Drop excess kernel-doc entry @key Robin Murphy (2): drm/tegra: vic: Fix DMA API misuse gpu: host1x: Add missing DMA API include Thierry Reding (8): Merge branch 'tegra-for-5.17-soc-opp' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into drm/tegra/for-next drm/tegra: Implement correct DMA-BUF semantics drm/tegra: Implement buffer object cache drm/tegra: Do not reference tegra_plane_funcs directly drm/tegra: Propagate errors from drm_gem_plane_helper_prepare_fb() drm/tegra: Support asynchronous commits for cursor drm/tegra: gr2d: Explicitly control module reset drm/tegra: vic: Handle tegra_drm_alloc() failure Wan Jiabing (1): drm/tegra: Remove duplicate struct declaration drivers/gpu/drm/tegra/Kconfig | 3 + drivers/gpu/drm/tegra/Makefile | 3 +- drivers/gpu/drm/tegra/dc.c | 194 +++++++++++++-- drivers/gpu/drm/tegra/dc.h | 3 + drivers/gpu/drm/tegra/drm.c | 30 ++- drivers/gpu/drm/tegra/drm.h | 1 + drivers/gpu/drm/tegra/gem.c | 171 +++++++++----- drivers/gpu/drm/tegra/gr2d.c | 151 +++++++++++- drivers/gpu/drm/tegra/gr3d.c | 353 +++++++++++++++++++++++----- drivers/gpu/drm/tegra/hdmi.c | 183 +++++++++++++-- drivers/gpu/drm/tegra/hub.h | 1 - drivers/gpu/drm/tegra/nvdec.c | 466 +++++++++++++++++++++++++++++++++++++ drivers/gpu/drm/tegra/plane.c | 65 ++---- drivers/gpu/drm/tegra/plane.h | 2 +- drivers/gpu/drm/tegra/rgb.c | 53 ++++- drivers/gpu/drm/tegra/submit.c | 77 ++++-- drivers/gpu/drm/tegra/uapi.c | 68 ++---- drivers/gpu/drm/tegra/uapi.h | 5 +- drivers/gpu/drm/tegra/vic.c | 61 +++-- drivers/gpu/host1x/Kconfig | 1 + drivers/gpu/host1x/bus.c | 80 ++++++- drivers/gpu/host1x/channel.c | 8 + drivers/gpu/host1x/debug.c | 15 ++ drivers/gpu/host1x/dev.c | 185 ++++++++++++--- drivers/gpu/host1x/dev.h | 5 +- drivers/gpu/host1x/hw/channel_hw.c | 44 ++-- drivers/gpu/host1x/intr.c | 3 - drivers/gpu/host1x/job.c | 160 +++++-------- drivers/gpu/host1x/job.h | 6 +- drivers/gpu/host1x/syncpt.c | 5 +- drivers/soc/tegra/common.c | 25 ++ include/linux/host1x.h | 76 ++++-- include/soc/tegra/common.h | 15 ++ 33 files changed, 2020 insertions(+), 498 deletions(-) create mode 100644 drivers/gpu/drm/tegra/nvdec.c
