* drm/vkms: Forward timer right after drm_crtc_handle_vblankDaniel Vetter2019-06-061-6/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit def35e7c592616bc09be328de8795e5e624a3cf8 Author: Shayenne Moura <shayenneluzmoura@gmail.com> Date: Wed Jan 30 14:06:36 2019 -0200 drm/vkms: Bugfix extra vblank frame we fixed the vblank counter to give accurate results outside of drm_crtc_handle_vblank, which fixed bugs around vblank timestamps being off-by-one and causing the vblank counter to jump when it shouldn't. The trouble is that this completely broke crc generation. Shayenne and Rodrigo tracked this down to the vblank timestamp going backwards in time somehow. Which then resulted in an underflow in drm_vblank.c code, which resulted in all kinds of things breaking really badly. The reason for this is that once we've called drm_crtc_handle_vblank and the hrtimer isn't forwarded yet, we're returning a vblank timestamp in the past. This race is really hard to hit since it's small, except when you enable crc generation: In that case there's a call to drm_crtc_accurate_vblank right in-betwen, so we're guaranteed to hit the bug. The fix is to roll the hrtimer forward _before_ we do the vblank processing (which has a side-effect of incrementing the vblank counter), and we always subtract one frame from the hrtimer - since now it's always one frame in the future. To make sure we don't hit this again also add a WARN_ON checking for whether our timestamp is somehow moving into the past, which is never should. This also aligns more with how real hw works: 1. first all registers are updated with the new timestamp/vblank counter values. 2. then an interrupt is generated 3. kernel interrupt handler eventually fires. So doing this aligns vkms closer with what drm_vblank.c expects. Document this also in a comment.

* drm/vkms: Remove useless call to drm_connector_register/unregister()Rodrigo Siqueira2019-06-061-10/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The function vkms_output_init() is invoked during the module initialization, and it handles the creation/configuration of the vkms essential elements (e.g., connectors, encoder, etc). Among the initializations, this function tries to initialize a connector and register it by calling drm_connector_register(). However, inside the drm_connector_register(), at the beginning of this function there is the following validation: if (!connector->dev->registered) return 0; In this sense, invoke drm_connector_register() after initializing the connector has no effect because the register field is false. The connector register happens when drm_dev_register() is invoked; the same issue exists with drm_connector_unregister(). Therefore, this commit removes the unnecessary call to drm_connector_register() and drm_connector_unregister().

* drm: Ignore drm_gem_vram_mm_funcs in generated documentationThomas Zimmermann2019-06-061-1/+1
| | | | | | | | | | | | The documentation tools interpret drm_gem_vram_mm_funcs as function and there appears to be no way of inline-documenting constants. This results in a warning by 'make htmldocs'. For now, removing drm_gem_vram_mm_funcs from generated documentation works around the issue.

* drm/virtio: Fix cache entry creation race.David Riley2019-06-061-1/+21
| | | | | | | | | | | | | | | | | | | virtio_gpu_cmd_get_capset would check for the existence of an entry under lock. If it was not found, it would unlock and call virtio_gpu_cmd_get_capset to create a new entry. The new entry would be added it to the list without checking if it was added by another task during the period where the lock was not held resulting in duplicate entries. Compounding this issue, virtio_gpu_cmd_capset_cb would stop iterating after find the first matching entry. Multiple callbacks would modify the first entry, but any subsequent entries and their associated waiters would eventually timeout since they don't become valid, also wasting memory along the way.

| | | | | | | | | | | | virtio_gpu_get_caps_ioctl could return success with invalid data if a second caller to the function occurred after the entry was created in virtio_gpu_cmd_get_capset but prior to the virtio_gpu_cmd_capset_cb callback being called. This could leak contents of memory as well since the caps_cache allocation is done without zeroing.

* drm/bridge/synopsys: dw-hdmi: Add "unwedge" for ddc busDouglas Anderson2019-06-051-16/+100
| | | | | | | | | | | | | | See the PhD thesis in the comments in this patch for details, but to summarize this adds a hacky "unwedge" feature to the dw_hdmi i2c bus to workaround what appears to be a hardware errata. This relies on a pinctrl entry to help change around muxing to perform the unwedge. NOTE that the specific TV this was tested on was the "Samsung UN40HU6950FXZA" and the specific port was the "STB" port.

* dt-bindings: drm/bridge/synopsys: dw-hdmi: Add "unwedge" for ddc busDouglas Anderson2019-06-051-0/+7
| | | | | | | | | | | | | | | | | In certain situations it was seen that we could wedge up the DDC bus on the HDMI adapter on rk3288. The only way to unwedge was to mux one of the pins over to GPIO output-driven-low temporarily and then quickly mux back. Full details can be found in the patch ("drm/bridge/synopsys: dw-hdmi: Add "unwedge" for ddc bus"). Since unwedge requires remuxing the pins, we first need to add to the bindings so that we can specify what state the pins should be in for unwedging.
