If anyone has any objections, please let me know. ------------------ From: Matt Roper [ Upstream commit 1046bc7b416814833a43af8e66c52b0ea71c2021 ] Wa_15010599737 was a workaround originally proposed (and ultimately rejected) for DG2-G10. There's no record of it ever being relevant or even considered for any other platforms. The specific bit this workaround was setting is documented as "This bit should be set to 1 for the DX9 API and 0 for all other APIs" which means that it should almost always be left at the default value of 0 on Linux. The register itself is directly accessible from userspace, so in the special cases where it might be relevant (e.g., Wine/Proton running Windows DX9 apps), the userspace drivers already have the ability to change the setting without involvement of the kernel.
