When a timeout of zero is specified, the caller is only interested in the fence status. In the current implementation, dma_fence_default_wait will always call schedule_timeout() at least once for an unsignaled fence. This adds a significant overhead to a fence status query. Avoid this overhead by returning early if a zero timeout is specified. v2: move early return after enable_signaling Signed-off-by:

Currently, the audio sampler clock is enabled from dw_hdmi_setup() at step E. and is kept enabled for later use. This clock should be enabled and disabled along with the actual audio stream and not always on (that is bad for PM). Furthermore, as described by the datasheet, the I2S variant needs to gate/ungate the clock when the stream is enabled/disabled. This commit adds a parameter to hdmi_audio_enable_clk() that controls when the audio sample clock must be enabled or disabled. Then, it adds the call to this function from dw_hdmi_i2s_audio_enable() and dw_hdmi_i2s_audio_disable(). Reviewed-by:

Currently, CTS+N is forced to zero as a workaround of the IP block for i.MX platforms. This is requested in the datasheet of the corresponding IP for AHB mode only. However, we have seen that it introduces glitches or delays when playing a sound on HDMI for I2S mode. This proves that we cannot keep the current functions for handling audio stream as-is if these contain workaround that are specific to a mode. This commit introduces two callbacks, one for each variant. dw_hdmi_setup defines the right function depending on the detected variant. Then, the exported functions dw_hdmi_audio_enable and dw_hdmi_audio_disable calls the corresponding callbacks Reviewed-by:

Until now, we've had to limit Raspberry Pi to 256MB of CMA memory to keep from triggering the hardware addressing bug between the tile binner and the tile alloc memory (where the top 4 bits come from the tile state data array's address). To work around that and allow more memory to be reserved for graphics, allocate a single BO to store tile state data arrays and tile alloc/overflow memory while the GPU is active, and make sure that that one BO doesn't happen to cross a 256MB boundary. With that in place, we can allocate textures and shaders anywhere in system memory (still contiguous, of course). Signed-off-by:

The HDMI driver is currently enabling all clocks at probe time and keeps the power-domain connected to the HDMI encoder enabled. Move all activation code to vc4_hdmi_encoder_enable() and make sure the clks and power domain are released when the HDMI encoder is not used by adding deactivation steps in vc4_hdmi_encoder_disable(). Note that the sequencing imposed by the IP requires that we move vc4_hdmi_encoder_mode_set() code into vc4_hdmi_encoder_enable(). Signed-off-by:

All the error codes we (ab)use are strictly not the right ones (since they're all for the vfs, and the only thing we're allowed to do from an ioctl is EINVAL). But ENOENT is the common error code for failed to look up an object throughout drm, so let's use it in the cma helpers, too. Note that this does change uabi for some drivers, but that shouldn't ba a problem: - other drivers (e.g. i915) already return ENOENT for invalid gem bo - userspace tends to only check for errors, not specific ones (except when ioctl restarting is needed) - if the gem bo isn't there a previous step (either creating or importing it) failed already, this situation should always be a userspace bug. Changing it does help with debugging userspace bugs though, by making error reporting more consistent. Cc: Laurent Pinchart <Laurent.pinchart@ideasonboard.com> Reviewed-by:

This doesn't yet introduce waits on another device's fences before vc4's rendering/display, because I don't have testcases for them. v2: Reuse dma_fence_free(), retitle commit message to clarify that it's not a full dma-buf fencing implementation yet.

I've broken this by removing the backoff handling from the set_config2atomic helper in commit 38b6441e Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed Mar 22 22:50:58 2017 +0100 drm/atomic-helper: Remove the backoff hack from set_config Fixing this properly would mean we get to wire the acquire_ctx all the way through vmwgfx fbdev code, and doing the same was tricky for the shared fbdev layer. Probably much better to look into refactoring the entire code to use the helpers, but since that's not a viable long-term solution fix the issue by open-coding a vmwgfx version of set_config, that does the legacy backoff dance internally. Note: Just compile-tested. The idea is to take drm_mode_set_config_internal(), remove the "is this a legacy driver" check, and whack the drm_atomic_legacy_backoff trickery at the end. Since drm_atomic_legacy_backoff is for atomic commits only we need to open-code it. Cc: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by:
