Description Barnabás Virágh 2020-03-08 20:57:22 UTC

For the upcoming xf86-video-impact driver, a new sysctl function is needed in the impact fbdev in the kernel, to efficiently handle multi area DMA flushes on the non-cache-coherent architecture of IP28 (SGI Indigo2 Impact 10000).

Without this patch, the xf86-video-impact driver falls back to PIO mode, which is slow.

For the patch to work, bug 710678 filed patch as a prerequisite is assumed.

Reproducible: Always
