In the event that the topology requests resources that have not been created by the system (because they are typically not represented in dpu_mdss_cfg ^1), the resource(s) in global_state (in this case DSC blocks, until their allocation/assignment is being sanity-checked in "drm/msm/dpu: Reject topologies for which no DSC blocks are available") remain NULL but will still be returned out of dpu_rm_get_assigned_resources, where the caller expects to get an array containing num_blks valid pointers (but instead gets these NULLs). To prevent this from happening, where null-pointer dereferences typically result in a hard-to-debug platform lockup, num_blks shouldn't increase past NULL blocks and will print an error and break instead. After all, max_blks represents the static size of the maximum number of blocks whereas the actual amount varies per platform. ^1: which can happen after a git rebase ended up moving additions to _dpu_cfg to a different struct which has the same patch context.

Marijn Suijten authored
Resource allocation of DSC blocks should behave more like LMs and CTLs where NULL resources (based on initial hw_blk creation via definitions in the catalog) are skipped ^1. The current hardcoded mapping of DSC blocks however means that resource allocation shouldn't succeed at all when the DSC block on the corresponding index doesn't exist, rather than searching for the next free block. This hardcoded mapping should be loosened separately as DPU 5.0.0 introduced a crossbar where DSC blocks can be "somewhat" freely bound to any PP and CTL (in proper pairs). ^1: which, on hardware that supports DSC, can happen after a git rebase ended up moving additions to _dpu_cfg to a different struct which has the same patch context.

According to downstream /and the comment copied from it/ this comparison should be the other way around. In other words, when the panel driver requests to use more slices per packet than what could be sent over this interface, it is bumped down to only use a single slice per packet (and strangely not the number of slices that could fit on the interface).

According to downstream the value to use for WORD_COUNT is bytes_per_pkt, which denotes the number of bytes in a packet based on how many slices have been configured by the panel driver times the width of a slice times the number of bytes per pixel. The DSC panels seen thus far use one byte per pixel, only one slice per packet, and a slice width of half the panel width leading to the desired bytes_per_pkt+1 value to be equal to hdisplay/2+1. This however isn't the case anymore for panels that configure two slices per packet, where the value should now be hdisplay+1. Note that the aforementioned panel (on a Sony Xperia XZ3, sdm845) with slice_count=1 has also been tested to successfully accept slice_count=2, which would have shown corrupted output previously.

Active CTLs have to configure what DSC block(s) have to be enabled, and what DSC block(s) have to be flushed; this value was initialized to zero resulting in the necessary register writes to never happen (or would write zero otherwise). This seems to have gotten lost in the DSC v4->v5 series while refactoring how the combination with merge_3d was handled.

The mask only describes the `irq_idx % 32` part, making it generally impossible to deduce what interrupt is being enabled/disabled. Since `debug/core_irq` in debugfs (and other prints) also include the full `DPU_IRQ_IDX()` value, print the same full value here for easier correlation instead of only adding the `irq_idx / 32` part. Furthermore, make the dbgstr messages more consistent. Signed-off-by:

There are 3 possible interrupt sources are handled by DP controller, HPDstatus, Controller state changes and Aux read/write transaction. At every irq, DP controller have to check isr status of every interrupt sources and service the interrupt if its isr status bits shows interrupts are pending. There is potential race condition may happen at current aux isr handler implementation since it is always complete dp_aux_cmd_fifo_tx() even irq is not for aux read or write transaction. This may cause aux read transaction return premature if host aux data read is in the middle of waiting for sink to complete transferring data to host while irq happen. This will cause host's receiving buffer contains unexpected data. This patch fixes this problem by checking aux isr and return immediately at aux isr handler if there are no any isr status bits set. Current there is a bug report regrading eDP edid corruption happen during system booting up. After lengthy debugging to found that VIDEO_READY interrupt was continuously firing during system booting up which cause dp_aux_isr() to complete dp_aux_cmd_fifo_tx() prematurely to retrieve data from aux hardware buffer which is not yet contains complete data transfer from sink.
