BTW, I don't think it was explicitly in the phoronix article, but the actual source for omapdrm is at drivers/staging/omapdrm. cheers, Jesse On Tue, May 15, 2012 at 8:03 PM, Jesse Barker wrote: > OK, so with respect to that article, we've been working with our > members to provide KMS drivers fo

OK, so with respect to that article, we've been working with our members to provide KMS drivers for their SoCs. The results are in varying states of completeness and availability, but I would expect that to improve in the coming cycles. You should be able to find DRM drivers for pandaboard (omapd

Hi Jesse, Here: http://www.phoronix.com/scan.php?page=news_item&px=OTI0MA and http://lists.freedesktop.org/archives/wayland-devel/2011-March/000855.html It doesn't propose a unified interface for 2D accelerators on SoCs, though. > There's nothing I'm aware of that would define what you are askin

Can you point out the article you're referring to that mentioned the Linaro project? There's nothing I'm aware of that would define what you are asking (apart from the Xserver's EXA framework which certainly isn't new or in the kernel). Even the interfaces exported by DRM require user space code

Hi Christian, Yes dma-buf is part of the picture, but rather if any work has been done to define an interface for the device itself, not the buffers. I do know that these are mostly managed from user-space for performance reasons, however I was curious to see if anything has been in the works for

Standardized kernel interface for 2D blitters

2012-05-14 Thread Ilyes Gouta
Hi, I've previously read (probably on Phoronix) that Linaro is working out a 'standard' kernel interface for 2D blitters IPs as commonly found on SoCs. Has it ever been the case? If yes, are there any documentation/references online? Thanks, -Ilyes _
