[Openpvrsgx-devgroup] DDK 1.17 on S5PV210

[Jonathan Bakker]

Hi,

I've managed to get the ti443x DDK 1.17 blobs running kmscube on s5pv210 (with SGX540-120).  I did have to make a binary change to them to look for the exynos DRM driver as opposed to the ompadrm driver (I suppose changing the DRM driver name would also work).  The command for editing the files are

printf "exynos\x00" > exynos && dd if=exynos of=/lib/libsrv_um.so.1.17.4948957 obs=1 seek=110644 conv=notrunc && dd if=exynos of=/lib/libdbm.so.1.17.4948957 obs=1 seek=5960 conv=notrunc && rm exynos

I've put the kernel driver part at https://github.com/xc-racer99/linux/tree/v5.5.1-all-devices-openpvr - note that I currently have the clock and power domain always enabled at probe as active power management is disabled for the blobs.  I'm not sure how the omap devices deal with this, but my "solution" would cause issues with increased power draw during suspend.
