[PATCH V2 1/2] ASoC: SOF: amd: move iram-dram fence register programming sequence

[PATCH V2 1/2] ASoC: SOF: amd: move iram-dram fence register programming sequence

[Vijendar Mukunda]

The existing code modifies IRAM and DRAM size after sha dma start for
vangogh platform. The problem with this sequence is that it might cause
sha dma failure when firmware code binary size is greater than the default
IRAM size. To fix this issue, Move the iram-dram fence register sequence
prior to sha dma start.

[PATCH V2 2/2] ASoC: SOF: amd: Fix for incorrect acp error register offsets

[Vijendar Mukunda]

Addition of 'dsp_intr_base' to ACP error register offsets points to
wrong register offsets in irq handler. Correct the acp error register
offsets. ACP error status register offset and acp error reason register
offset got changed from ACP6.0 onwards. Add 'acp_error_stat' and
'acp_sw0_i2s_err_reason' as descriptor fields in sof_amd_acp_desc
structure and update the values based on the ACP variant.
From Rembrandt platform onwards, errors related to SW1 Soundwire manager
instance/I2S controller connected on P1 power tile is reported with
ACP_SW1_I2S_ERROR_REASON register. Add conditional check for the same.

  SHA DMA?

             Thus move the IRAM-DRAM …?


How do you think about to offer cover letters for patch series?

I think above one seems to be okay.

 I think above one seems to be okay.

 As these are individual fixes, I don't think a cover letter should
be included in the patch series.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
