[PATCH v2 0/5] Add support to print sub-block registers in dpu hw catalog

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The purpose of this patch series is to add support to print the registers
of sub-blocks in the DPU hardware catalog and fix the order in which all
hardware blocks are dumped for a device core dump. This involves:

1. Changing data structure from stack to queue to fix the printing order
of the device core dump.

2. Removing redundant suffix of sub-block names.

3. Removing redundant prefix of sub-block names.

4. Eliminating unused variable from relevant macros.

5. Defining names for sub-blocks that have not yet been defined.

6. Implementing wrapper function that prints the registers of sub-blocks
when there is a need.

Sample Output of the sspp_0 block and its sub-blocks for devcore dump:
======sspp_0======
...registers
...
====sspp_0_scaler====
...
...
====sspp_0_csc====
...
...
====next_block====
...

Changes in v2:
- Changed spelling "sub block" to "sub-block" or "sblk".
- Capitalized DPU.
- Eliminated multiplexer/wrapper function. Inlined instead.
- Changed if statements from feature checks to length checks.
- Squashed prefix and suffix patch into one.
- Link to v1: https://lore.kernel.org/r/20230622-devcoredump_patch-v1-0-3b2cdcc6a576@xxxxxxxxxxx
