[PATCH v4 0/5] Wave515 decoder IP support

From: Ivan Bornyakov
Date: Mon Apr 15 2024 - 06:08:24 EST


Initial support for Wave515 multi-decoder IP among other refinements.
This was tested on FPGA prototype, so wave5_dt_ids[] was not expanded.

fluster score for JCT-VC-HEVC_V1 testsuite with
GStreamer-H.265-V4L2-Gst1.0 decoder is 132/147

The issue with Main10 tests is that fluster expects decoded file to be
in yuv420p10le format while this driver decodes HEVC Main10 into 8-bit
yuv420p. Though result is looks alright to the naked eye, proper
decoding into yuv420p10le is to be added.

The rest failed fluster tests are common with Wave521.

ChangeLog:
v1:
https://lore.kernel.org/linux-media/20240318144225.30835-1-brnkv.i1@xxxxxxxxx/
v2:
https://lore.kernel.org/linux-media/20240325064102.9278-1-brnkv.i1@xxxxxxxxx/
* drop patch "dt-bindings: media: cnm,wave521c: drop resets restriction"
The only user of Wave5 in mainline is TI K3 boards, thus there is
no real need to alter dt-bindings
* in patch "media: chips-media: wave5: support decoding HEVC Main10 profile"
add check for flag "support_hevc10bit_dec"
* in patch "media: chips-media: wave5: support reset lines" move
reset_control_deassert() out of else branch, add
reset_control_assert() to probe error path.
* rework patch "media: chips-media: wave5: drop "sram-size" DT prop"
- don't move alloc/free form device open/close
- intead of exact configuration of reserved SRAM memory in DT and
allocating all of it, allocate all available SRAM memory up to
WAVE5_MAX_SRAM_SIZE from whatever pool provided.
* adjust patch "media: chips-media: wave5: support Wave515 decoder"
according to changes in patches
"media: chips-media: wave5: support decoding HEVC Main10 profile" and
"media: chips-media: wave5: drop "sram-size" DT prop"
v3:
https://lore.kernel.org/linux-media/20240405164112.24571-1-brnkv.i1@xxxxxxxxx/
* reword patch "media: chips-media: wave5: separate irq setup routine"
a bit.
* in patch "media: chips-media: wave5: drop "sram-size" DT prop"
- move MAX_SRAM_SIZE define into match_data->sram_size
- add placeholders for validation that allocated SRAM memory is
enough to encode/decode bitstream of given resolution before
setting W5_USE_SEC_AXI and W5_CMD_ENC_PIC_USE_SEC_AXI registers
- reword accordingly
* in patch "media: chips-media: wave5: support Wave515 decoder"
- add comments around SRAM memory allocation/freeing about
Wave515 specifics
- add comments about BSOPTION_RD_PTR_VALID_FLAG bit in
W5_BS_OPTION register
- add W[AVE]521_ prefix to defines, for wich there are W[AVE]515_
alternatieves
- add semi-magic Wave515 specific formulas to estimate SRAM usage
v4:
* rebase onto next-20240415, no functional changes
