This is needed for proper synchronization with display on another DRM device (pl111 or tinydrm) with buffers produced by vc4 V3D. Fixes the new igt vc4_dmabuf_poll testcase, and rendering of one of the glmark2 desktop tests on pl111+vc4. 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:

We're trying to access vop registers here, so need to make sure the pm domain is on. Normally it should be enabled by the bootloader, but there's no guarantee of it. And if we wanna do unbind/bind, it would also cause the device to hang. And this patch also does these: 1/ move vop_initial to the end of vop_bind for eaiser error handling. 2/ correct the err_put_pm_runtime of vop_enable. Signed-off-by:

Normally we do this in drm_mode_config_cleanup. But: 1/ analogix dp's connector is allocated in bind, and freed after unbind.

The plat_data->input_bus_format and plat_data->input_bus_encoding are unsigned long and are always >=0, but the value 0 was still considered as RGB888 for input_bus_format and default color space for input_bus_encoding in the reworked code. This patch changes the if statement check for a non-zero value to either use the default input bus_format and/or bus_encoding for a zero value and the provided bus_format and/or bus_encoding for a non zero value. Thanks to Dan Carpenter for his bug report at [1]. Tested on Amlogic P230 (with CSC enabled for YUV444 to RGB) and Rockchip RK3288 ACT8846 EVB Board (no CSC involved, direct RGB passthrough).

The OMAP driver has its own OF graph helpers that are similar to the common helpers. This commit replaces most of the calls with the common helpers. There's still a couple of custom helpers left, but the driver needs more extensive changes to get rid of them. In dss_init_ports, we invert the loop, looping through the known ports and matching them to DT nodes rather than looping thru DT nodes and matching them to the ports. Signed-off-by:

Graph connections are often "no connects" depending on the particular board, so we want to avoid spurious messages. Plus the kernel is not a DT validator. Signed-off-by:

Convert drivers to use the new of_graph_get_remote_node() helper instead of parsing the endpoint node and then getting the remote device node. Now drivers can just specify the device node and which port/endpoint and get back the connected remote device node. The details of the graph binding are nicely abstracted into the core OF graph code. This changes some error messages to debug messages (in the graph core). Graph connections are often "no connects" depending on the particular board, so we want to avoid spurious messages.

Many drivers have a common pattern of searching the OF graph for either an attached panel or bridge and then finding the DRM struct for the panel or bridge. Also, most drivers need to handle deferred probing when the DRM device is not yet instantiated. Create a common function, drm_of_find_panel_or_bridge, to find the connected node and the associated DRM panel or bridge device. Signed-off-by:

Now that handle_conflicting_encoders no longer touches active state, so there's no need to do the check quite that late any more. Doing it with all the other checks makes it a lot more clear what the below block tries to accomplish, and this feels like a better place to put the check. Signed-off-by:

Now that handle_conflicting_encoders cannot disable crtc's any more it makes sense to set all the changed flags in 1 place. This makes the code slightly less magical. The (now removed) comment is out of date. The only reason the active_changed was set late was because handle_conflicting_encoders could disable connectors. This is no longer the case, and we can put everything in 1 place. Signed-off-by:

Maarten Lankhorst authored
Currently we use a flag to change behavior in atomic commit whether a conflicting encoder should be enabled or disabled. This is used for the legacy set_config helper, which disables connectors that have a conflicting encoder but not part of the active crtc list. There's no need for this to be handled in atomic commit, it could be done in the set_config helper instead. This will let the atomic check function reject any conflicting encoders, while set_config can disable conflicting crtc's. This makes it possible to recalculate the changed flags in 1 loop.

Maarten Lankhorst authored
mode_valid() called from drm_helper_probe_single_connector_modes() may need to look at connector->state because what a valid mode is may depend on connector properties being set. For example some HDMI modes might be rejected when a connector property forces the connector into DVI mode. Some implementations of detect() already lock all state, so we have to pass an acquire_ctx to them to prevent a deadlock. This means changing the function signature of detect() slightly, and passing the acquire_ctx for locking multiple crtc's. For the callbacks, it will always be non-zero. To allow callers not to worry about this, drm_helper_probe_detect_ctx is added which might handle -EDEADLK for you. Changes since v1: - Always set ctx parameter. Changes since v2: - Always take connection_mutex when probing. Changes since v3: - Remove the ctx from intel_dp_long_pulse, and add WARN_ON(!connection_mutex) (danvet) - Update docs to clarify the locking situation. (danvet) Signed-off-by:

The goal is to push all the kms locking down into these separate _atomic and _legacy functions, so that we can correctly pass the acquire ctx into all atomic drivers. Instead of playing games with hidden ctx in mode_config.acquire_ctx. All the fbdev state will be protected by a new fbdev private lock that Thierry is working on. This here is just prep by creating a clean split between atomic and legacy paths, which also simplifies the control flow a bit. Reviewed-by:

I got confused every time I audited what that lock_all is doing in there until realizing it's for legacy kms only. Make that a notch more obvious by having 2 entirely different paths. While at it also move the atomic version of this into drm_framebuffer.c, there's no reason it needs to be in drm_atomic.c. That way it becomes a simple static function. Reviewed-by:
