In this patch series, we are adding support for lower end Adreno 5 series GPUs, such as A508, A509 and A512 that we have found in the Qualcomm SDM630, SDM636 and SDM660 SoCs.
On a note, adding support for these three units, also adds 99% of the required "things" for another two GPUs, A505 and A506 but, even if adding them requires literally two lines of code, noone of us has got any SoC equipped with these ones hence we wouldn't be able to test. Even though there is basically no reason for them to not work correctly, kernel side, I chose to avoid adding the two "magic" lines.
Anyway, this patchset also addresses some issues that we've found in the A5XX part of the Adreno driver, regarding a logic mistake in one of the VPC protect values and a forced overwrite of the register named A5XX_PC_DBG_ECO_CNTL, forcing the setting of vtxFifo and primFifo thresholds that was valid only for higher end GPUs.
This patch series has been tested on the following devices: - Sony Xperia XA2 Ultra (SDM630 Nile Discovery) - Sony Xperia 10 (SDM630 Ganges Kirin) - Sony Xperia 10 Plus (SDM636 Ganges Mermaid)
Changes in v3: - Rebased on 5.11-rc3 - Changed emails to reflect new ones - Tested on F(x)Tec Pro1 and Xperia XZ Premium (MSM8998)
Changes in v2: - Define REG_A5XX_UCHE_MODE_CNTL and fix open-coded REG_A5XX_VPC_DBG_ECO_CNTL in the all flat shading optimization disablement commit, as requested by Rob Clark.
