[git pull] drm zpos property support
by Dave Airlie 03 Aug '16

03 Aug '16

Hi Linus, This tree was waiting on some media stuff I hadn't had time to get a stable branchpoint off, so I just waited until it was all in your tree first, it's been around a bit on the list and shouldn't affect anything outside adding the generic API and moving some ARM drivers to using it. Dave. The following changes since commit dfd2e9ab6a7db56a5f5bb55f71485a92613c8e11: drm/i915: Check PSR setup time vs. vblank length (2016-08-03 07:06:41 +1000) are available in the git repository at: git://people.freedesktop.org/~airlied/linux tags/drm-for-v4.8-zpos for you to fetch changes up to 586efded6b8beb932e9a356f351b0c681503358f: Merge branch 'generic-zpos-v8' of http://git.linaro.org/people/benjamin.gaignard/kernel into drm-next (2016-08-03 08:40:24 +1000) ---------------------------------------------------------------- Benjamin Gaignard (3): Merge remote-tracking branch 'media_tree/vsp1' into generic-zpos-v8 drm: sti: use generic zpos for plane drm: rcar: use generic code for managing zpos plane property Dave Airlie (1): Merge branch 'generic-zpos-v8' of http://git.linaro.org/people/benjamin.gaignard/kernel into drm-next Marek Szyprowski (2): drm: add generic zpos property drm/exynos: use generic code for managing zpos plane property Documentation/gpu/kms-properties.csv | 1 + drivers/gpu/drm/Makefile | 2 +- drivers/gpu/drm/drm_atomic.c | 4 + drivers/gpu/drm/drm_atomic_helper.c | 7 + drivers/gpu/drm/drm_blend.c | 238 ++++++++++++++++++++++++++++++ drivers/gpu/drm/drm_crtc_internal.h | 4 + drivers/gpu/drm/exynos/exynos_drm_drv.h | 2 - drivers/gpu/drm/exynos/exynos_drm_plane.c | 67 ++------- drivers/gpu/drm/exynos/exynos_mixer.c | 6 +- drivers/gpu/drm/rcar-du/rcar_du_crtc.c | 2 +- drivers/gpu/drm/rcar-du/rcar_du_drv.h | 1 - drivers/gpu/drm/rcar-du/rcar_du_kms.c | 5 - drivers/gpu/drm/rcar-du/rcar_du_plane.c | 9 +- drivers/gpu/drm/rcar-du/rcar_du_plane.h | 2 - drivers/gpu/drm/rcar-du/rcar_du_vsp.c | 14 +- drivers/gpu/drm/sti/sti_cursor.c | 4 +- drivers/gpu/drm/sti/sti_gdp.c | 4 +- drivers/gpu/drm/sti/sti_hqvdp.c | 4 +- drivers/gpu/drm/sti/sti_mixer.c | 9 +- drivers/gpu/drm/sti/sti_plane.c | 78 ++++------ drivers/gpu/drm/sti/sti_plane.h | 7 +- include/drm/drm_crtc.h | 20 +++ 22 files changed, 334 insertions(+), 156 deletions(-) create mode 100644 drivers/gpu/drm/drm_blend.c

The issue was observed on HD7750 and HD7950. The pattern and list of the 12 dEQP-GLES2 tests causing systematic GPU lockups is the following: dEQP-GLES2.functional.shaders.loops.while_{constant,uniform,dynamic}.{conditional,double}_continue_{vertex,fragment} You can find in the attachments the dEQP GLES2 tests logs and some dmesg logs captured during these GPU lockups. I am available to collect further logs, if you could provide me instructions, or to test patches and report back to help resolve the issue. NOTE: I've already tried to define R600_DEBUG=nosb which in android-x86 has to be done in init.x86.rc before building the iso image, but then running a test plan with the aforementioned failed tests, I get again systematic GPU lockups.

[PATCH] drm/i915: cleanup_plane_fb: also drop reference to current state wait_req
by Keith Packard 02 Aug '16

02 Aug '16

There are two paths into intel_cleanup_plane_fb, the normal completion path and the failure path. In the failure case, intel_cleanup_plane_fb is called before drm_atomic_helper_swap_state, so any wait_req reference made in intel_prepare_plane_fb will be in old_intel_state->wait_req. In the normal completion path, drm_atomic_helper_swap_state has already been called, so the plane state holding the just-used wait_req will not be in old_intel_state->wait_req, rather it will be in the state associated with the plane itself. Clearing this reference ensures that the wait_req will be freed as soon as it the related mode setting operation is complete, rather than waiting for some future mode setting operation to eventually dereference it. The existing dereference of old_intel_state->wait_req is still required as that will hold the wait_req when the mode setting operation fails. cc: Daniel Vetter <daniel.vetter(a)intel.com> cc: David Airlie <airlied(a)linux.ie> cc: intel-gfx(a)lists.freedesktop.org cc: dri-devel(a)lists.freedesktop.org Signed-off-by: Keith Packard <keithp(a)keithp.com> --- drivers/gpu/drm/i915/intel_display.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index 3074c56..dbabaf3 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -13924,6 +13924,7 @@ intel_cleanup_plane_fb(struct drm_plane *plane, struct drm_device *dev = plane->dev; struct intel_plane *intel_plane = to_intel_plane(plane); struct intel_plane_state *old_intel_state; + struct intel_plane_state *intel_state = to_intel_plane_state(plane->state); struct drm_i915_gem_object *old_obj = intel_fb_obj(old_state->fb); struct drm_i915_gem_object *obj = intel_fb_obj(plane->state->fb); @@ -13941,6 +13942,7 @@ intel_cleanup_plane_fb(struct drm_plane *plane, (obj && !(obj->frontbuffer_bits & intel_plane->frontbuffer_bit))) i915_gem_track_fb(old_obj, obj, intel_plane->frontbuffer_bit); + i915_gem_request_assign(&intel_state->wait_req, NULL); i915_gem_request_assign(&old_intel_state->wait_req, NULL); } -- 2.8.1

[PATCH 0197/1285] Replace numeric parameter like 0444 with macro
by Baole Ni 02 Aug '16

02 Aug '16

I find that the developers often just specified the numeric value when calling a macro which is defined with a parameter for access permission. As we know, these numeric value for access permission have had the corresponding macro, and that using macro can improve the robustness and readability of the code, thus, I suggest replacing the numeric parameter with the macro.
