Marek Report a possible irq lock inversion dependency warning when commit 81a06f1d ("Revert "drm/rockchip: vop2: Use regcache_sync() to fix suspend/resume"") lands linux-next. I can reproduce this warning with: CONFIG_PROVE_LOCKING=y CONFIG_DEBUG_LOCKDEP=y It seems than when use regmap_reinit_cache at runtime whith Mark's commit 3d59c22b ("drm/rockchip: vop2: Convert to use maple tree register cache"), it will trigger a possible irq lock inversion dependency warning. One solution is switch back to REGCACHE_RBTREE, but it seems that REGCACHE_MAPLE is the future, so I avoid using regmap_reinit_cache, and drop all the regcache when vop is disabled, then we get a fresh start at next enbable time.

If we get a deadlock after the fb lookup in drm_mode_page_flip_ioctl() we proceed to unref the fb and then retry the whole thing from the top. But we forget to reset the fb pointer back to NULL, and so if we then get another error during the retry, before the fb lookup, we proceed the unref the same fb again without having gotten another reference. The end result is that the fb will (eventually) end up being freed while it's still in use. Reset fb to NULL once we've unreffed it to avoid doing it again until we've done another fb lookup. This turned out to be pretty easy to hit on a DG2 when doing async flips (and CONFIG_DEBUG_WW_MUTEX_SLOWPATH=y). The first symptom I saw that drm_closefb() simply got stuck in a busy loop while walking the framebuffer list. Fortunately I was able to convince it to oops instead, and from there it was easier to track down the culprit. Cc: stable@vger.kernel.org Signed-off-by:

While writing the matching IGT suite I discovered that it's possible to cause a kernel oops when using DRM_IOCTL_PVR_CREATE_HWRT_DATASET when the call to hwrt_init_common_fw_structure() fails. Use an unwind-type error path to avoid cleaning up the object using the the release function before it is fully resolved. Signed-off-by:

Unwinding loop in error path for this function uses unsigned limit variable, causing the promotion of the signed counter variable. --> 204 for (; pfn >= start_pfn; pfn--) ^^^^^^^^^^^^^^^^ If start_pfn can be zero then this is an endless loop. I've seen this code in other places as well. This loop is slightly off as well. It should decrement pfn on the first iteration. Fix by making the loop limit variables signed. Also fix missing predecrement by modifying to while loop. Reported-by:

Mediatek 8173 and 8183 SOCs have a separate display controller and GPU with different drivers for each. For mt8173, the GPU driver is powervr and the display driver is mediatek. In the case of mt8183, the GPU driver is panfrost and the display driver is mediatek. Setting IGT_FORCE_DRIVER to panfrost for mt8173 is not the expected driver. So set mediatek for mt8173. Support to test both GPU and display drivers for these ARM SOCs will be added in the next patch series to increase test coverage. Acked-by:

Even though we were rolling our own custom state for the vc4 HDMI controller driver, we were still using the generic helper to destroy that state. It was mostly working since the underlying state is the first member of our state so the pointers are probably equal in all relevant cases, but it's still fragile so let's fix this properly.
