[PATCH v2] drm: make drm_syncobj_array_wait() use the range hrtimer feature

2021-12-18 Thread Tatsuyuki Ishi
select(), poll() and epoll_wait() all already supports high-precision timeout handling. This patch makes drm_syncobj_array_wait() to handle the timeout in high precision using the same heuristics and functions implemented for select(). v2: Fix a name error resulting in NULL dereference. Signed-of

How to fix screen resolution detection?

2021-12-18 Thread Alan Stern
The screen resolution on my laptop is not reported accurately. Here's an extract from the output of xdpyinfo: screen #0: dimensions:3200x1800 pixels (847x476 millimeters) resolution:96x96 dots per inch The number of pixels is correct, but the size and resolution values smack of a b

[PATCH 1/3] drm/stm: dsi: move lane capability detection in probe()

2021-12-18 Thread Antonio Borneo
There is no need to re-compute the dsi lane capability because it only depends on dsi hw version. Since dsi hw version is detected at probe(), move there also the assignment of dsi lane capability. Signed-off-by: Antonio Borneo --- To: David Airlie To: Daniel Vetter To: Andrzej Hajda To: Neil

[PATCH 3/3] drm/stm: dsi: provide the implementation of mode_valid()

2021-12-18 Thread Antonio Borneo
The dsi has several constraints on the video modes it can support, mainly due to the frequencies that can be generated by the PLL integrated in the DSI device. Verify that the required HS clock can be generated by the PLL. The dsi clock from the dsi PLL and the ltdc pixel clock are asynchronous.

To evaluate the validity of a video mode, some additional internal value has to be passed to the platform implementation. Extend the prototype of mode_valid(). Signed-off-by: Antonio Borneo --- To: David Airlie To: Daniel Vetter To: Andrzej Hajda To: Neil Armstrong To: Robert Foss To: Laure

'prev_engine' was declared inside the output loop and checked in the inner after at least 1 pass of either loop. The variable should be declared outside both loops as it needs to be persistent across the entire loop structure. Fixes: e5e32171a2cf ("drm/i915/guc: Connect UAPI to GuC multi-lrc inter
