* drm/mipi-dsi: add mipi_dsi_usleep_range helperJerome Brunet2024-06-261-0/+7
| | | | | | | | | | | | Like for mipi_dsi_msleep(), usleep_range() may often be called in between mipi_dsi_dcs_*() functions and needs a multi compatible counter part.

* gpu: ipu-v3: pre: don't use fixed timeout when waiting for safe windowLucas Stach2024-06-261-8/+14
| | | | | | | | | | | | | | | | | | | | | The timeout when waiting for the PRE safe window is rather short, as normally we would only need to wait a few dozen usecs for the problematic scanline region to pass and we don't want to spin too long in case something goes wrong. This however mixes badly with preemption, as we can easily get scheduled away from the CPU for a longer time than our timeout, in which case we would hit a spurious timeout and wrongly skip the PRE update. Instead of disabling preemption across the wait loop, potentially impacting the overall system latency, use a wait loop with a fixed max number of iterations, so time spent away from the CPU is not accounted against the timeout budget.

* gpu: ipu-v3: pre: add dynamic buffer layout reconfigurationLucas Stach2024-06-263-30/+63
| | | | | | | | | | | | | | | | | | imx-drm doesn't mandate a modeset when the framebuffer modifier changes, but currently the tile prefetch and resolve (TPR) configuration of the PRE is only set up on the initial modeset. As the TPR configuration is double buffered, same as all the other PRE states, we can support dynamic reconfiguration of the buffer layout from one frame to another. As switching between (super-)tiled and linear prefetch needs to touch the CTRL register make sure to do the reconfiguration inside the safe window.

* drm/ttm/tests: Let ttm_bo_test consider different ww_mutex implementation.Sebastian Andrzej Siewior2024-06-201-1/+7
| | | | | | | | | | | | | | | | | | | | | | PREEMPT_RT has a different locking implementation for ww_mutex. The base mutex of struct ww_mutex is declared as struct WW_MUTEX_BASE. The latter is defined as `mutex' for non-PREEMPT_RT builds and `rt_mutex' for PREEMPT_RT builds. Using mutex_lock() directly on the base mutex in ttm_bo_reserve_deadlock() leads to compile error on PREEMPT_RT. The locking-selftest has its own defines to deal with this and it is probably best to defines the needed one within the test program since their usefulness is limited outside of well known selftests. Provide ww_mutex_base_lock() which points to the correct function for PREEMPT_RT and non-PREEMPT_RT builds.
