Dikshita Agarwal July 14, 2021, 7:01 a.m. UTC
This series enables support for 6xx venus encode/decode on sc7280.

The driver changes are dependent on [1]yaml and [2]dts patches.

[1] https://patchwork.kernel.org/project/linux-arm-msm/list/?series=484019
[2] https://patchwork.kernel.org/project/linux-arm-msm/list/?series=484727

Changes since v2:
 - no longer considering client buffer requirement to calculate
   output buffer min count.
 - addressed comments on v2 (stanimir).

Dikshita Agarwal (7):
  venus: firmware: enable no tz fw loading for sc7280
  media: venus: core: Add sc7280 DT compatible and resource data
  media: venus: Add num_vpp_pipes to resource structure
  media: venus: hfi: Skip AON register programming for V6 1pipe
  venus: vdec: set work route to fw
  media: venus: helpers: update NUM_MBS macro calculation
  media: venus: Set buffer to FW based on FW min count requirement.

Hi Dikshita,

Could you please rebase the patchset on top of current
linux_media/master branch and resend it as v4?

No need to initialize ret to zero.

Could you add a comment why HFI_BUFFER_INTERNAL_SCRATCH_1 is included in
condition and not included in below 'if' condition?

Also in regards to inst->fw_min_cnt, can we pass fw_min_cnt as input to
get_bufreq via 'req' structure, i.e.

req.count_min = inst->fw_min_cnt;

ret = venus_helper_get_bufreq(inst, type, &req);

inst->fw_min_cnt = req.count_min

?

we can actually remove HFI_BUFFER_INTERNAL_SCRATCH_1 from this condition 
now
since count_min is no longer being used for SCRATCH_1 buffer 
calculation.
