Driver has been tested on Toshiba AC100 and Acer A500, it should work on any Tegra20 device. In userspace this driver is utilized by libvdpau-tegra [0] that implements VDPAU interface, so any video player that supports VDPAU can provide accelerated video decoding on Tegra20 on Linux. [0] https://github.com/grate-driver/libvdpau-tegra Change log: v4: - Added mmio-sram "IRAM DT node" patch from Vladimir Zapolskiy to the series, I modified it to cover all Tegra's and not only Tegra20 - Utilized genalloc for the reservation of IRAM region as per Vladimir's suggestion, VDE driver now selects SRAM driver in Kconfig - Added defconfig patch to the series - Described VDE registers in DT per HW unit, excluding BSE-A / UCQ and holes between the units - Extended DT compatibility property with Tegra30/114/124/132 in the binding doc. - Removed BSE-A interrupt from the DT binding because it's very likely that Audio Bitstream Engine isn't integrated with VDE - Removed UCQ interrupt from the DT binding because in TRM it is represented as a distinct HW block that probably should have its own driver - Addressed v3 review comments: factored out DT binding addition into a standalone patch, moved binding to media/, removed clocks/resets-names v3: - Suppressed compilation warnings reported by 'kbuild test robot' v2: - Addressed v1 review comments from Stephen Warren and Dan Carpenter - Implemented runtime PM - Miscellaneous code cleanups - Changed 'TODO' - CC'd media maintainers for the review as per Greg's K-H request, v1 can be viewed at https://lkml.org/lkml/2017/9/25/606 Dmitry Osipenko (4): media: dt: bindings: Add binding for NVIDIA Tegra Video Decoder Engine staging: Introduce NVIDIA Tegra video decoder driver ARM: dts: tegra20: Add video decoder node ARM: defconfig: tegra: Enable Video Decoder driver Vladimir Zapolskiy (1): ARM: tegra: Add device tree node to describe IRAM .../devicetree/bindings/media/nvidia,tegra-vde.txt | 55 + arch/arm/boot/dts/tegra114.dtsi | 8 + arch/arm/boot/dts/tegra124.dtsi | 8 + arch/arm/boot/dts/tegra20.dtsi | 35 + arch/arm/boot/dts/tegra30.dtsi | 8 + arch/arm/configs/tegra_defconfig | 2 +- drivers/staging/Kconfig | 2 + drivers/staging/Makefile | 1 + drivers/staging/tegra-vde/Kconfig | 7 + drivers/staging/tegra-vde/Makefile | 1 + drivers/staging/tegra-vde/TODO | 5 + drivers/staging/tegra-vde/uapi.h | 101 ++ drivers/staging/tegra-vde/vde.c | 1209 ++++++++++++++++++++ 13 files changed, 1441 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/media/nvidia,tegra-vde.txt create mode 100644 drivers/staging/tegra-vde/Kconfig create mode 100644 drivers/staging/tegra-vde/Makefile create mode 100644 drivers/staging/tegra-vde/TODO create mode 100644 drivers/staging/tegra-vde/uapi.h create mode 100644 drivers/staging/tegra-vde/vde.c -- 2.14.2
