[PATCH v4 00/17] Venus QoL / maintainability fixes

[Konrad Dybcio]

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!

[PATCH v4 01/17] media: venus: hfi_venus: Only consider sys_idle_indicator on V1

[Konrad Dybcio]

As per information from Qualcomm [1], this property is not really
supported beyond msm8916 (HFI V1) and some newer HFI versions really
dislike receiving it, going as far as crashing the device.

Only consider toggling it (via the module option) on HFIV1.
While at it, get rid of the global static variable (which defaulted
to zero) which was never explicitly assigned to for V1.

Note: [1] is a reply to the actual message in question, as lore did not
properly receive some of the emails..

[PATCH v4 02/17] media: venus: hfi_venus: Write to VIDC_CTRL_INIT after unmasking interrupts

[Konrad Dybcio]

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.

[PATCH v4 03/17] media: venus: Introduce VPU version distinction

[Konrad Dybcio]

The Video Processing Unit hardware version is the differentiator, based
on which the video driver should decide which code paths to take.

Up until now, we've relied on HFI versions instead, but that was just
a happy accident between recent SoCs. Add a field in the res struct
and add correlated definitions that will be used to account for the
aforementioned differences.

[Konrad Dybcio]

The qcom_scm_mem_protect_video_var accepts two sets of <addr size>
pairs as arguments. They describe the virtual address ranges of the
CP (Content Protection) and CP_NONPIXEL regions. It is however not
immediately obvious how to obtain these values.

Leave a comment explaining how one can translate the vendor device
tree properties for use with the mainline driver.

way to override the remapped fields. Replace the macros with actual
get/set pairs to fix that.

[PATCH v4 17/17] media: venus: hfi_venus: Restrict writing SCIACMDARG3 to Venus V1/V2

[Konrad Dybcio]

This write was last present on msm-3.10, which means before HFI3XX
platforms were introduced. Guard it with an appropriate if condition.

Does not seem to have any adverse effects on at least SM8250.
