Hi Dave,
this is the next pull quested for stashed up radeon fixes for 3.15.
Highlights are:
1. Avoid sending SIGBUS on CPU access just because kernel can't handle
buffer placement.
2. Some fixes for VM page table updates and buffer placements.
3. Fixing two typos in the PLL and SI register spec.
4. Checking VCE buffers ranges.
5. Adding a mutex for I2C access.
6. Mullins and non-VGA pci class fixes from Alex.
This is starting to feel a bit large, we should be in regression
fixing, oopses and black screens at this point,
The main ones I'm concerned about are the VCE buffer ranges and i2c
mutex, whether these fix known problems or issues,
For the VCE buffer range checks that fixed a lockup I experienced while
working on the userspace driver (VCE writing over the end of a buffer
into an shader, GPU then trying to execute the messed up shader
code...). Apart from that VCE is a new feature for 3.15 so we can't
really break it compared to 3.14.
I can't judge on the I2C mutex since that was Alex suggestion and I'm
not sure how invasive and/or necessary this is.
Regards,
Christian.
Dave.
