Add enable_writeback feature to vkms_config as a module. Signed-off-by:
-
Sumera Priyadarsini authored
Currently, data for the device instance is held by vkms_device. Add a separate type, vkms_config to contain configuration details for the device and various modes to be later used by configfs. This config data stays constant once the device is created. Accordingly, add vkms_create and vkms_destroy to initialize/destroy device through configfs. Currently, they are being called from vkms_init and vkms_exit, but will be evoked from configfs later on. When configfs is added, device configuration will be tracked by configfs and only vkms device lifetime will be handled by vkms_init and vkms_exit functions. Modify usage of enable_cursor feature to reflect the changes in relevant files. Co-developed-by:

The comment says the layout and options use 8 bits, and the shift uses 8 bits. However the mask is 0xf, ie. 0b00001111 (4 bits). This could be surprising when introducing new layouts or options that take more than 4 bits, as this would silently drop the high bits. Make the masks consistent with the comment and the shift.

drm_dp_check_and_send_link_address discovers MST device topology. It can return both positive and negative values. When it returns positive values there is no error found. If it returns negative values there is error found, such as get NAK , timeout, etc. Following drm_kms_helper_hotplug_event should be called when drm_dp_check_and_send_link_address returns positive value.

This fixes the following problems with the s6e63m0 display bindings: - When used on the DSI bus, the panel is listed directly as a subnode on the DSI host so the "port" node is not compulsory. Remove "port" from required properties. - The panel contains its own backlight control, so reference the backlight common properties and list default-brightness and max-brightness as supported but optional properties.

Now that we have a graph schema, rework the display related schemas to use it. Mostly this is adding a reference to graph.yaml and dropping duplicate parts from schemas. In panel-common.yaml, 'ports' is dropped. Any binding using 'ports' should be one with more than 1 port node, and the binding must define what each port is. Note that ti,sn65dsi86.yaml, ti,tfp410,yaml and toshiba,tc358768.yaml will need further updates to use video-interfaces.yaml once that lands.

Merge tag 'topic/dp-hdmi-2.1-pcon-2020-12-23' of git://anongit.freedesktop.org/drm/drm-intel into drm-next Add support for DP-HDMI2.1 PCON From the series cover letter: This patch series attempts to add support for a DP-HDMI2.1 Protocol Convertor. The VESA spec for the HDMI2.1 PCON are proposed in Errata E5 to DisplayPort_v2.0: https://vesa.org/join-vesamemberships/member-downloads/?action=stamp&fileid=42299 The details are mentioned in: VESA DP-to-HDMI PCON Specification Standalone Document https://groups.vesa.org/wg/DP/document/15651 This series starts with adding support for FRL (Fixed Rate Link) Training between the PCON and HDMI2.1 sink. As per HDMI2.1 specification, a new data-channel or lane is added in FRL mode, by repurposing the TMDS clock Channel. Through FRL, higher bit-rate can be supported, ie. up to 12 Gbps/lane (48 Gbps over 4 lanes). With these patches, the HDMI2.1 PCON can be configured to achieve FRL training based on the maximum FRL rate supported by the panel, source and the PCON. The approach is to add the support for FRL training between PCON and HDMI2.1 sink and gradually add other blocks for supporting higher resolutions and other HDMI2.1 features, that can be supported by pcon for the sources that do not natively support HDMI2.1. This is done before the DP Link training between the source and PCON is started. In case of FRL training is not achieved, the PCON will work in the regular TMDS mode, without HDMI2.1 feature support. Any interruption in FRL training between the PCON and HDMI2.1 sink is notified through IRQ_HPD. On receiving the IRQ_HPD the concerned DPCD registers are read and FRL training is re-attempted. Currently, we have tested the FRL training and are able to enable 4K display with TGL Platform + Realtek PCON RTD2173 with HDMI2.1 supporting panel. Signed-off-by:

Recently a regression was introduced which caused TTM's buffer eviction to attempt to evict already-pinned BOs, causing issues with buffer eviction under memory pressure along with suspend/resume: nouveau 0000:1f:00.0: DRM: evicting buffers... nouveau 0000:1f:00.0: DRM: Moving pinned object 00000000c428c3ff! nouveau 0000:1f:00.0: fifo: fault 00 [READ] at 0000000000200000 engine 04 [BAR1] client 07 [HUB/HOST_CPU] reason 02 [PTE] on channel -1 [00ffeaa000 unknown] nouveau 0000:1f:00.0: fifo: DROPPED_MMU_FAULT 00001000 nouveau 0000:1f:00.0: fifo: fault 01 [WRITE] at 0000000000020000 engine 0c [HOST6] client 07 [HUB/HOST_CPU] reason 02 [PTE] on channel 1 [00ffb28000 DRM] nouveau 0000:1f:00.0: fifo: channel 1: killed nouveau 0000:1f:00.0: fifo: runlist 0: scheduled for recovery [TTM] Buffer eviction failed nouveau 0000:1f:00.0: DRM: waiting for kernel channels to go idle... nouveau 0000:1f:00.0: DRM: failed to idle channel 1 [DRM] nouveau 0000:1f:00.0: DRM: resuming display... After some bisection and investigation, it appears this resulted from the recent changes to ttm_bo_move_to_lru_tail(). Previously when a buffer was pinned, the buffer would be removed from the LRU once ttm_bo_unreserve to maintain the LRU list when pinning or unpinning BOs. However, since: commit 3d1a88e1 ("drm/ttm: cleanup LRU handling further") We've been exiting from ttm_bo_move_to_lru_tail() at the very beginning of the function if the bo we're looking at is pinned, resulting in the pinned BO never getting removed from the lru and as a result - causing issues when it eventually becomes time for eviction. So, let's fix this by calling ttm_bo_del_from_lru() from ttm_bo_move_to_lru_tail() in the event that we're dealing with a pinned buffer. v2 (chk): reduce to only the fixing one liner since we always want to call the callback whenever we would move on the LRU.

MMU exception conditions are reported in the V3D_MMU_CTRL register as write-1-to-clear (W1C) bits. The MMU interrupt handling code clears any exceptions, but does so by masking out any other bits and writing the result back. There are some important control bits in that register, including MMU_ENABLE, so a safer approach is to simply write back the value just read unaltered. Signed-off-by:
