2022-04-27drm/msm/mdp5: check the return of kzalloc()Xiaoke Wang1-0/+3
[ Upstream commit 047ae665577776b7feb11bd4f81f46627cff95e7 ] kzalloc() is a memory allocation function which can return NULL when some internal memory errors happen. So it is better to check it to prevent potential wrong memory access. Besides, since mdp5_plane_reset() is void type, so we should better set `plane-state` to NULL after releasing it.

Add safe lut configuration for all the targets in dpu driver as per QOS recommendation. Issue reported on SC7280: With wait-for-safe feature in smmu enabled, RT client buffer levels are checked to be safe before smmu invalidation. Since display was always set to unsafe it was delaying the invalidaiton process thus impacting the performance on NRT clients such as eMMC and NVMe. Validated this change on SC7280, With this change eMMC performance has improved significantly.

2021-06-23drm/msm/dpu: Avoid ABBA deadlock between IRQ modulesBjorn Andersson4-46/+63
Handling of the interrupt callback lists is done in dpu_core_irq.c, under the "cb_lock" spinlock. When these operations results in the need for enableing or disabling the IRQ in the hardware the code jumps to dpu_hw_interrupts.c, which protects its operations with "irq_lock" spinlock. When an interrupt fires, dpu_hw_intr_dispatch_irq() inspects the hardware state while holding the "irq_lock" spinlock and jumps to dpu_core_irq_callback_handler() to invoke the registered handlers, which traverses the callback list under the "cb_lock" spinlock. As such, in the event that these happens concurrently we'll end up with a deadlock. Prior to '1c1e7763a6d4 ("drm/msm/dpu: simplify IRQ enabling/disabling")' the enable/disable of the hardware interrupt was done outside the "cb_lock" region, optimitically by using an atomic enable-counter for each interrupt and an warning print if someone changed the list between the atomic_read and the time the operation concluded. Rather than re-introducing the large array of atomics, this change embraces the fact that dpu_core_irq and dpu_hw_interrupts are deeply entangled and make them share the single "irq_lock". Following this step it's suggested that we squash the two parts into a single irq handling thing.
