Backmerge drm-next to be able to apply Chris' connector_unregister_all cleanup (need latest i915 and sun4i state for that). Also there's a trivial conflict in ttm_bo.c that git rerere fails to remember. Signed-off-by:Daniel Vetter <daniel.vetter@intel.com>

The ttm_tt_destroy() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by:

vGEM buffers are useful for passing data between software clients and hardware renders. By allowing the user to create and attach fences to the exported vGEM buffers (on the dma-buf), the user can implement a deferred renderer and queue hardware operations like flipping and then signal the buffer readiness (i.e. this allows the user to schedule operations out-of-order, but have them complete in-order). This also makes it much easier to write tightly controlled testcases for dma-buf fencing and signaling between hardware drivers. v2: Don't pretend the fences exist in an ordered timeline, but allocate a separate fence-context for each fence so that the fences are unordered. v3: Make the debug output more interesting, and show the signaled status. v4: Automatically signal the fence to prevent userspace from indefinitely hanging drivers.

drm/tegra: Changes for v4.8-rc1 This set of changes contains a bunch of cleanups to the host1x driver as well as the addition of a pin controller for DPAUX, which is required by boards to configure the DPAUX pads in AUX mode (for DisplayPort) or I2C mode (for HDMI and DDC). Included is also a bit of rework of the SOR driver in preparation to add DisplayPort support as well as some refactoring and cleanup. Finally, all output drivers are converted to runtime PM, which greatly simplifies the handling of clocks and resets. * tag 'drm/tegra/for-4.8-rc1' of git://anongit.freedesktop.org/tegra/linux: (35 commits) drm/tegra: sor: Reject HDMI 2.0 modes drm/tegra: sor: Prepare for generic PM domain support drm/tegra: dsi: Prepare for generic PM domain support drm/tegra: sor: Make XBAR configurable per SoC drm/tegra: sor: Use sor1_src clock to set parent for HDMI dt-bindings: display: tegra: Add source clock for SOR drm/tegra: sor: Implement sor1_brick clock drm/tegra: sor: Implement runtime PM drm/tegra: hdmi: Implement runtime PM drm/tegra: dsi: Implement runtime PM drm/tegra: dc: Implement runtime PM drm/tegra: hdmi: Enable audio over HDMI drm/tegra: sor: Do not support deep color modes drm/tegra: sor: Extract tegra_sor_mode_set() drm/tegra: sor: Split out tegra_sor_apply_config() drm/tegra: sor: Rename tegra_sor_calc_config() drm/tegra: sor: Factor out tegra_sor_set_parent_clock() drm/tegra: dpaux: Add pinctrl support dt-bindings: Add bindings for Tegra DPAUX pinctrl driver drm/tegra: Prepare DPAUX for supporting generic PM domains ...

Userspace needs to know if it can create shaders that do branching. Otherwise, for backwards compatibility with old kernels it needs to lower if statements to conditional assignments. Signed-off-by: -
Eric Anholt authored
We're already checking that branch instructions are between the start of the shader and the proper PROG_END sequence. The other thing we need to make branching safe is to verify that the shader doesn't read past the end of the uniforms stream. To do that, we require that at any basic block reading uniforms have the following instructions: load_imm temp, <next offset within uniform stream> add unif_addr, temp, unif The instructions are generated by userspace, and the kernel verifies that the load_imm is of the expected offset, and that the add adds it to a uniform. We track which uniform in the stream that is, and at draw call time fix up the uniform stream to have the address of the start of the shader's uniforms at that location. Signed-off-by: -
