This project is about shaping existing GPL Linux kernel drivers for the PVR/SGX5 architecture so that they can become accepted into drivers/gpu/drm. It is NOT about reverse engineering or user-space components (firmware and libs), just the kernel device drivers. There is also be some glue code for the processor of the SoC (OMAP, Sunxi, jz4780).

So i tried running this with postmarketOS (which is alpine linux) and it has its own mesa-pvr-dri-classic and sgx-ddk-um aports, with that i got the following error

The driver fails somewhere :(

Here is the first error PVR_DPF((PVR_DBG_ERROR,"PollForValueKM: Timeout. Expected 0x%x but found 0x%x (mask 0x%x).", ui32Value, ui32ActualValue, ui32Mask)); (https://github.com/openpvrsgx-devgroup/linux_openpvrsgx/blob/letux-pvrsrvkm-5.12-rc1/drivers/gpu/drm/pvrsgx/1.17.4948957/eurasia_km/services4/srvkm/common/pvrsrv.c#L1073) well it seems pui32LinMemAddr is wrong and causes this error.

Cannot find any way to fix this and thus cant get 3D acceleration :( My GPU is SGX540 (OMAP4430)

Hi there,

I'm the one that contributed the pmOS aports. This, however, is an issue with the kernel driver. You need to add -DPVR_LINUX_MEM_AREA_USE_VMAP to the Makefile of the module. Not sure why, but this is what has had to be done for a number of kernel versions now, I forget which version it started being needed in.

Note that I only tested the pmOS aports on s5pv210, but they should work for other SGX540 devices.

Hello xc-racer thanks for the reply :D, will try the solution and tell the result! Thanks a lot for your work on powervr <3

Edit : It works!! Do i need to create a PR, or are you people gonna add the patch?

It should be in the repos already, it was @tmlind that figured this out IIRC. Might have been missed on a specific branch/revision.

If you can tell me which patch should be applied to which branch on

https://github.com/openpvrsgx-devgroup/linux_openpvrsgx/branches

I can check and add.
