The host1x driver uses currently syncpoints statically from host1x point of view. If we do a wait inside a job, it always has a constant value to wait. host1x supports also doing relative syncpoint waits with respect to syncpoint bases. This allows doing multiple operations inside a single submit and waiting an operation to complete before moving to next one. This set of patches adds support for syncpoint bases to host1x driver and enables the support for gr2d client. I have tested the series using the host1x test application (available at [0], function test_wait_base() in tests/tegra/host1x/tegra_host1x_test.c) on cardhu. I would appreciate help in reviewing the series and testing the patches on other boards. Changes in v2: - Reordered various code blocks to improve code consistency - Functions host1x_syncpt_alloc() and host1x_syncpt_request() take now a single bitfield argument instead of separate boolean arguments - Added a separate ioctl call for querying the base associated with some syncpoint [0] https://gitorious.org/linux-host1x/libdrm-host1x Arto Merilainen (4): gpu: host1x: Add 'flags' field to syncpt request gpu: host1x: Add syncpoint base support drm/tegra: Deliver syncpoint base to user space drm/tegra: Reserve base for gr2d drivers/gpu/host1x/dev.h | 2 ++ drivers/gpu/host1x/drm/drm.c | 25 +++++++++++++ drivers/gpu/host1x/drm/gr2d.c | 2 +- drivers/gpu/host1x/hw/channel_hw.c | 19 ++++++++++ drivers/gpu/host1x/hw/hw_host1x01_uclass.h | 6 ++++ drivers/gpu/host1x/syncpt.c | 58 +++++++++++++++++++++++++----- drivers/gpu/host1x/syncpt.h | 10 +++++- include/uapi/drm/tegra_drm.h | 26 +++++++++----- 8 files changed, 128 insertions(+), 20 deletions(-) -- 1.8.1.5 -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
