v3 -> v4: - Rebase on Stanimir's venus-for-next-v6.5 - Collapse 2 identical if-statements in "Sanitize venus_boot_core() per-VPU-version" - Reword "Assign registers based on VPU version" - Check for IS_IRIS2_1() instead of wrongly checking for core->use_tz, update commit msg in "media: venus: firmware: Correct IS_V6() checks" - Access correct struct fields in "Use newly-introduced hfi_buffer_requirements accessors", drop Bryan's r-b
v3: https://lore.kernel.org/r/20230228-topic-venus-v3-0-6092ae43b58f@linaro.org
v2 -> v3: - Rephrase "Write to VIDC_CTRL_INIT after unmasking interrupts" commit msg - Drop "Remap bufreq fields on HFI6XX" - Rephrase "Introduce VPU version distinction" commit msg - Better explain "Leave a clue for homegrown porters" - Drop incorrect fixes tags/rephrase version check alternations - Drop AR50L/IRIS1 from if-conditions, they'll be introduced separately - pick up tags - rebase on next-20230517 (no effective changes)
v2: https://lore.kernel.org/r/20230228-topic-venus-v2-0-d95d14949c79@linaro.org
v1 -> v2: - Move "Write to VIDC_CTRL_INIT after unmasking interrupts" up and add a Fixes tag & Cc stable - Reword the comment in "Correct IS_V6() checks" - Move up "media: venus: Remap bufreq fields on HFI6XX", add Fixes and Cc stable - Use better English in "Use newly-introduced hfi_buffer_requirements accessors" commit message - Mention "Restrict writing SCIACMDARG3 to Venus V1/V2" doesn't seem to regress SM8250 in the commit message - Pick up tags (note: I capitalized the R in Dikshita's 'reviewed-by' and removed one occurrence of random '**' to make sure review tools like b4 don't go crazy) - Handle AR50_LITE in "Assign registers based on VPU version" - Drop /* VPUn */ comments, they're invalid as explained by Vikash - Take a different approach to the sys_idle problem in patch 1
v1: https://lore.kernel.org/r/20230228-topic-venus-v1-0-58c2c88384e9@linaro.org
Currently upstream assumes all (well, almost all - see 7280 or CrOS specific checks) Venus implementations using the same version of the Hardware Firmware Interface can be treated the same way. This is however not the case.
This series tries to introduce the groundwork to start differentiating them based on the VPU (Video Processing Unit) hardware type, fixes a couple of issues that were an effect of that generalized assumption and lays the foundation for supporting 8150 (IRIS1) and SM6115/QCM2290 (AR50 Lite), which will hopefully come soon.
Tested on 8250, but pretty please test it on your boards too!

Best regards,
The startup procedure shouldn't be started with interrupts masked, as that may entail silent failures.
Kick off initialization only after the interrupts are unmasked.
