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 v4: - Added review tags - Link to v3: https://lore.kernel.org/r/20230622-devcoredump_patch-v3-0-83601b72eb67@xxxxxxxxxxx Changes in v3: - Split sub-block changes and main block changes into two commits - Corrected typo in comment located in DSC for loop block - Eliminated variables mmio and base - Dropped unnecessary "%s" - Link to v2: https://lore.kernel.org/r/20230622-devcoredump_patch-v2-0-9e90a87d393f@xxxxxxxxxxx Changes in v2: - Changed spelling "sub block" to "sub-block" or "sblk". - Capitalized DPU. - Eliminated multiplexer/wrapper function.
