drm/amd/display: Fix flip-done timeouts on mode1 reset

2026-07-24T14:26:42Z

The vblank on/off callbacks mixed use of amdgpu_irq_get/put() and amdgpu_dm_crtc_set_vupdate_irq() to enable and disable IRQs. With get/put, base driver will callback into DC to disable IRQs when refcount == 0. With set_vupdate_irq(), DC is called directly to disable IRQs, bypassing base driver's refcount tracking. During gpu reset, base driver can restore IRQs via amdgpu_irq_gpu_reset_resume_helper() > amdgpu_irq_update(). So if get/put() is not used (i.e. refcount == 0), then vupdate_irq will be disabled. This is problematic if DRM requests vblank on before amdgpu_irq_update() is called: drm_vblank_on() > set_vupdate_irq() enables vupdate_irq, but the refcount is still 0. gpu_reset_resume_helper() > irq_update() then immediately disables it, thus leading to flip done timeouts. This is made worse on DCN since VUPDATE_NO_LOCK is the only IRQ enabled. Prior to 8382cd234981, a combination of GRPH_FLIP and VSTARTUP IRQs were used, and they used get/put(). This explains why 8382cd234981 exposed this issue. Fix by using get/put() instead of set_vupdate_irq(). DCE is unchanged, since it relies on unbalanced enable/disable calls based on VRR status, and hence requires direct set_vupdate_irq(). Plus, it also uses GRPH_FLIP and VLINE IRQs, which are properly tracked by get/put().

Revert "drm/pagemap: Guard HPAGE_PMD_ORDER use with CONFIG_ARCH_ENABLE_THP_MIGRATION"

2026-07-24T06:02:14Z

This reverts commit 04b177544a040cbafab760d6b766381c6b22e0a8. The original author requested it to be reverted, as it conflicts with changes in the -next branch for MM: "I'm not sure who is doing the drm-misc-fixes PR, but if you are can you omit this patch: https://patchwork.freedesktop.org/series/170865/ I guess this conflicts with MM changes in their next tree and it easy enough on our side to do this slightly differently to avoid a conflict so going to post revert + a different change.

drm/vc4: Shut down BO cache timer before teardown

2026-07-23T23:07:23Z

The BO cache timer callback schedules time_work, and time_work can rearm the timer through vc4_bo_cache_free_old(). vc4_bo_cache_destroy() deletes the timer and then cancels the work, which does not break that cycle: the work being cancelled can rearm the timer, and the timer then queues work again after teardown. Use timer_shutdown_sync() instead, so the timer cannot be rearmed and the cycle ends with cancel_work_sync(). Fixes: c826a6e10644 ("drm/vc4: Add a BO cache.")
