[PATCH v2 0/2] Exynos850 GPU support
Posted by Thomas Turner 1 month, 1 week ago
Hi all,
This is my first time sending patches to linux so apologies for
mistakes. This series provides basic GPU support to the Exynos850
platform, making use of the Mali G52 GPU through the panfrost driver.

Thomas Turner (2):
  dt-bindings: gpu: arm,mali-bifrost: add exynos850-mali compatible
  arm64: dts: exynos850: Add GPU/Mali Bifrost node

Hi Thomas,

On the next submission, could you please also add my email

It is interesting topic.

Offtopic: I have working patches that enable cpu idle states on Exynos850
but they are not upstreameable due to PSCI (needs some argument
shift in one of the PSCI calls due to messed up MPIDRs).
If you will be interested to test/use that, please let me know.

Sure thing.

Absolutely would be interested to try and test that on my ERD850 device,
feel free to send patches/instructions my way.

On another side note, I noticed that on the e850-96 you setup basic PMIC
functionality in u-boot, on ERD850 we also do a similar thing via a
secondary bootloader (uniLoader), was curious to know whether you or Sam
have tried implementing PMIC capabilities into the Linux kernel at all and
if so how successful or unsuccessful has it been?

Best Regards,
Tom

Again: slow down.

Why does this appear under empty subject thread?

Best regards,
