Subject: [PATCHv8 0/9] Support for Tegra 2D hardware
This set of patches adds support for Tegra20 and Tegra30 host1x and
2D. It is based on linux-next-20130322 with RTC fixes applied.
Changes in this version:
* Own version of framebuffer driver due to move to own allocator
* Thanks to Thierry Reding for help
* Miscellaneous variable name, whitespace and IOCTL interface cleanups
* Bug fixes:
* Validator enabled again
* Added new class 2D strechblit
* Dropped patch "Support CMA object preallocation"
Changes in version 7:
* host1x memory data structures refactored
* Some "nvhost" leftovers renamed to host1x
Changes in version 6:
* Rebased on latest tegradrm
* Renamed tegradrm's host1x to host1x_drm
* Indentation and line split fixed to follow tegradrm convention
* Pointers to platform_device replaced with pointers to device
* Added host1x allocator, and wired it in
* Debug spew code fixed to access mem handles from host1x_job
* CDMA code doesn't keep the mem handles anymore
* Push buffer ops have been made generic code
* Removed the pin_array optimization in host1x_job to simplify code
* Large number of smaller changes
The driver implements an allocator using the dma mapping API. Each buffer is
assigned an ops structure to operate on it.
host1x is the driver that controls host1x hardware. It supports
host1x command channels, synchronization, and memory management. It
is sectioned into logical driver under drivers/gpu/host1x and
physical driver under drivers/host1x/hw. The physical driver is
compiled with the hardware headers of the particular host1x version.
The hardware units are described (briefly) in the Tegra2 TRM. Wiki
page http://http.download.nvidia.com/tegra-public-appnotes/host1x.html
also contains a short description of the functionality.
The patch set merges tegradrm into host1x and adds 2D driver, which
uses host1x channels and sync points. The patch set also adds user
space API to tegradrm for accessing host1x and 2D.
The changes to add support to libdrm are in
git@...orious.org:linux-host1x/libdrm-host1x.git
