Hi, not many changes in v2: Changed address-cells and size-cells for the Host1x device tree node to have value 1, since all subdevices fit in the lower 4G. Also dropped the incorrect change about this from the dt-bindings patch. Thanks to Rob for pointing this out. Mikko Notes for v1: Hi everyone, this series adds basic support for the Host1x channel engine and the VIC 2d compositor unit on Tegra186. The first three patches do the required device tree changes, the fourth patch updates the device tree binding documentation, and the two remaining patches add the actual implementation, almost all of which is in Host1x itself. The Tegra186 Host1x is a relatively large update over previous generations, which can be seen in the diffstat. The biggest change is that Host1x is now contains separate hypervisor and vm register apertures to support virtualization at the hardware level. This driver, however, currently assumes that this instance of Linux is the sole operating system having access to the hardware. This combined with increased numbers of supported channels and syncpoints have caused a number of register space changes that are responsible for most of the updated code. The series has been tested on the Jetson TX1 (T210) and TX2 (T186) using the host1x_test test suite available at http://github.com/cyndis/host1x_test The series itself is available at http://github.com/cyndis/linux, branch host1x-t186-1 Cheers, Mikko Mikko Perttunen (6): arm64: tegra: Add #power-domain-cells for BPMP arm64: tegra: Add host1x on Tegra186 arm64: tegra: Add VIC on Tegra186 dt-bindings: host1x: Add Tegra186 information gpu: host1x: Add Tegra186 support drm/tegra: Add Tegra186 support for VIC .../display/tegra/nvidia,tegra20-host1x.txt | 4 + arch/arm64/boot/dts/nvidia/tegra186.dtsi | 31 ++++ drivers/gpu/drm/tegra/drm.c | 1 + drivers/gpu/drm/tegra/vic.c | 10 ++ drivers/gpu/host1x/Makefile | 3 +- drivers/gpu/host1x/dev.c | 60 ++++++- drivers/gpu/host1x/dev.h | 4 + drivers/gpu/host1x/hw/cdma_hw.c | 49 +++--- drivers/gpu/host1x/hw/debug_hw.c | 137 +--------------- drivers/gpu/host1x/hw/debug_hw_1x01.c | 154 ++++++++++++++++++ drivers/gpu/host1x/hw/debug_hw_1x06.c | 133 +++++++++++++++ drivers/gpu/host1x/hw/host1x01.c | 2 + drivers/gpu/host1x/hw/host1x02.c | 2 + drivers/gpu/host1x/hw/host1x04.c | 2 + drivers/gpu/host1x/hw/host1x05.c | 2 + drivers/gpu/host1x/hw/host1x06.c | 44 +++++ drivers/gpu/host1x/hw/host1x06.h | 26 +++ drivers/gpu/host1x/hw/host1x06_hardware.h | 142 ++++++++++++++++ drivers/gpu/host1x/hw/hw_host1x06_hypervisor.h | 32 ++++ drivers/gpu/host1x/hw/hw_host1x06_uclass.h | 181 +++++++++++++++++++++ drivers/gpu/host1x/hw/hw_host1x06_vm.h | 47 ++++++ drivers/gpu/host1x/hw/intr_hw.c | 29 ++-- 22 files changed, 926 insertions(+), 169 deletions(-) create mode 100644 drivers/gpu/host1x/hw/debug_hw_1x01.c create mode 100644 drivers/gpu/host1x/hw/debug_hw_1x06.c create mode 100644 drivers/gpu/host1x/hw/host1x06.c create mode 100644 drivers/gpu/host1x/hw/host1x06.h create mode 100644 drivers/gpu/host1x/hw/host1x06_hardware.h create mode 100644 drivers/gpu/host1x/hw/hw_host1x06_hypervisor.h create mode 100644 drivers/gpu/host1x/hw/hw_host1x06_uclass.h create mode 100644 drivers/gpu/host1x/hw/hw_host1x06_vm.h -- 2.14.1 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
