2023-10-27drm/doc: describe PATH format for DP MSTSimon Ser
This is already uAPI, xserver parses it. It's useful to document since user-space might want to lookup the parent connector. Additionally, people (me included) have misunderstood the PATH property for being stable across reboots, but since a KMS object ID is baked in there that's not the case. So PATH shouldn't be used as-is in config files and such.

2023-10-27drm: introduce CLOSEFB IOCTLSimon Ser
This new IOCTL allows callers to close a framebuffer without disabling planes or CRTCs. This takes inspiration from Rob Clark's unref_fb IOCTL [1] and DRM_MODE_FB_PERSIST [2]. User-space patch for wlroots available at [3]. IGT test available at [4]. v2: add an extra pad field just in case we want to extend this IOCTL in the future (Pekka, Sima).

2023-10-27drm: extract closefb logic in separate functionSimon Ser
drm_mode_rmfb performs two operations: drop the FB from the file_priv->fbs list, and make sure the FB is no longer used on a plane.

2023-10-26drm/sched: Convert the GPU scheduler to variable number of run-queuesLuben Tuikov
The GPU scheduler has now a variable number of run-queues, which are set up at drm_sched_init() time. This way, each driver announces how many run-queues it requires (supports) per each GPU scheduler it creates. Note, that run-queues correspond to scheduler "priorities", thus if the number of run-queues is set to 1 at drm_sched_init(), then that scheduler supports a single run-queue, i.e. single "priority". If a driver further sets a single entity per run-queue, then this creates a 1-to-1 correspondence between a scheduler and a scheduled entity.

2023-10-19drm/panel: ili9882t: Avoid blurred screen from fast sleepCong Yang
At present, we have found that there may be a problem of blurred screen during fast sleep/resume. The direct cause of the blurred screen is that the IC does not receive 0x28/0x10. Because of the particularity of the IC, before the panel enters sleep hid must stop scanning, as i2c_hid_core_suspend before ili9882t_disable. If move the ili9882t_enter_sleep_mode function to ili9882t_unprepare, touch reset will pull low before panel entersleep, which does not meet the timing requirements.. So in order to solve this problem, the IC can handle it through the exception mechanism when it cannot receive 0x28/0x10 command. Handling exceptions requires a reset 50ms delay. Refer to vendor detailed analysis [1]. Ilitek vendor also suggested switching the page before entering sleep to avoid panel IC not receiving 0x28/0x10 command. Note: 0x28 is display off, 0x10 is sleep in.

2023-10-19drm/panel: ili9882t: Break out as separate driverCong Yang
The Starry ILI9882t-based panel should never have been part of the boe tv101wum driver, it is clearly based on the Ilitek ILI9882t display controller and if you look at the custom command sequences for the panel these clearly contain the signature Ilitek page switch (0xff) commands. The hardware has nothing in common with the other panels supported by this driver. Break this out into a separate driver and config symbol instead. If the placement here is out of convenience for using similar code, we should consider creating a helper library instead.

2023-10-18drm/ssd130x: Add support for the SSD132x OLED controller familyJavier Martinez Canillas
The Solomon SSD132x controllers (such as the SSD1322, SSD1325 and SSD1327) are used by 16 grayscale dot matrix OLED panels, extend the driver to also support this chip family. Instead adding an indirection level to allow the same modesetting pipeline to be used by both controller families, add another pipeline for SSD132x. This leads to some code duplication but it makes the driver easier to read and reason about. Once other controller families are added (e.g: SSD133x), some common code can be factored out in driver helpers to be shared by the different families. But that can be done later once these patterns emerge.

2023-10-18drm/ssd130x: Replace .page_height field in device info with a constantJavier Martinez Canillas
This deemed useful to avoid hardcoding a page height and allow to support other Solomon controller families, but dividing the screen in pages seems to be something that is specific to the SSD130x chip family. For example, SSD132x chip family divides the screen in segments (columns) and common outputs (rows), so the concept of screen pages does not exist for the SSD132x family. Let's drop this field from the device info struct and just use a constant SSD130X_PAGE_HEIGHT macro to define the page height. While being there, replace hardcoded 8 values in places where it is used as the page height.
