[Intel-gfx] opengl version supported for compat contexts

Hi, Could somebody please let me know the opengl version supported by the gallium-3d driver when requesting a compat profile? I only own too old hardware and had to discover the "classic" driver it is still at < OpenGL-4.4 for compact contexts. Thanks & best regards, Clemens _

[Intel-gfx] How to avoid "GTT mapping a busy miptree BO" stalls?

Hello, I am currently working on an application which has to stream huge amounts of texture data to the GPU. I use multiple buffers to avoid mapping a buffer which is currently involved in a DMA operation, so there is typically a delay of more than 1 frame between triggering an upload with glTexSu

[Intel-gfx] Output problems with displayport-hdmi kable on arrandale based hp elitebook 2540p

Hi, I recently bought a HP Elitebook 2540p, which is arrandale based and features a displayport connector (VGA as well). Because quality over VGA is quite bad with my Asus VW266H monitor (1920x1200; vga, hdmi, dvi) I bought a displayport<-->hdmi cable so I could use the digital output. However, a
