|
|
||
| Disable GPU to avoid adreno errors during display commit as there is | ||
| no plan to enable GPU rendering in near future on QCM6490 IDP board. | ||

There was a problem hiding this comment. Simply: NAK. The GPU is present onboard, so there is no need to disable it. There was a problem hiding this comment. Moreover, per Ritesh's email this patch is not necessary at all. GPU works on this platform. There was a problem hiding this comment. Few of the Conrad's Adreno 643+ fixes are yet to be backported. We are in discussion with our GPU team regarding the same and adreno firmware loading enablement. There was a problem hiding this comment. GPU on SC7280 has been supported upstream since 5.16. ZAP shader has been supported for ages. I fail to see what is so special about the QCM6490 which is supposed to be very close to SC7280. There was a problem hiding this comment. So, yes, please backport the patches and provide the firmware for the board. |

| configurable | ||
|
|
||
| Like other Qualcomm PMICs the PM7250B can be used on different addresses | ||
| on the SPMI bus. Use similar defines like the PMK8350 to make this | ||
| possible but skip the ifndef based on maintainer feedback. | ||

With the above configs set to m, when I tried initially it was working. But later on I found that on multiple reboots, it's not working most of the time. But when the above configs are set as y, the device boots to shell consistently. In the failure case, the device is getting stuck before UFS enumeration and hence the panel and backlight modules are not loaded.
DSI PHY supply(vreg_l10c_0p88) is shared among UFS and USB as well. We tried below experiments suspecting it is a shared resource issue:
So, it's not related to the shared supply between DSI PHY and UFS.
Below are the last set of logs in the failure case:
