Some BARs (like GK20A's) do not support being ioremapped write-combined. Add a boolean property to the BAR structure and handle that case in the Nouveau BO implementation.

Hello everyone, GK20A is the Kepler-based GPU used in the upcoming Tegra K1 chips. The following patches perform architectural changes to Nouveau that are necessary to support non-PCI GPUs and add initial support for GK20A. Although the support is still very basic and more user-space changes will be needed to make the full graphics stack run on top of it, we were able to successfully open

Hi everyone, Here is the second batch of patches to add GK20A support to Nouveau. This time we are adding the actual chip support, and this series brings the driver to a point where a slightly-tweaked Mesa successfully runs shaders and renders triangles on GBM! Many thanks to Thierry Reding and the people on the #nouveau IRC channel for their help without which we would not have reached this

Latest patches for GK20A, taking comments received for v3 into account. Changes since v3: - use only pfn_to_page() and page_to_pfn() in GK20A's FB. These functions are present on every arch and the physical address to page frame number conversion is also consistently a shift of PAGE_SHIFT. This part will probably be replaced by something nicer in the future anyway. - fixed a warning on

Hi everyone, Way overdue v2 of the final patches that enable basic GK20A support. Hopefully all the issues raised with v1 have been addressed. Changes since v1: - Use gk20a clock driver by Ben instead of twiddling nv04's - Name new classes after gk20a instead of nvea - Addressed comments about BAR initialization code factorization - Removed non-essential code which only purpose was to avoid

Changes since v2: - Enabled software class - Removed unneeded changes to nouveau_accel_init() - Replaced use of architecture-private pfn_to_dma() and dma_to_pfn() with the portable page_to_phys()/phys_to_page() - Fixed incorrect comment/commit log talking about bytes instead of words Hope this looks good! Once this gets merged the next set will be to use this driver on Jetson and Venice2
