97586c422b drm/radeon/r6xx/r7xx: further safe reg clean up
- remove a few more drm only regs
- remove sampler, alu, bool, loop constant regs.
  They are set via separate packet3's already

5f77df368c drm/radeon/r6xx/r7xx: CS parser fixes
- Drop some more safe regs taht userspace shouldn't hit
- Constant base regs need relocs.  This allows us to use
constant buffers rather than the constant register file.
Also we don't want userspace to be able to set arbitrary
mc base values for the const caches.
- Track SQ_CONFIG so we know whether userspace is using
the cfile or constant buffers.

961fb597c1 drm/radeon/kms: r600/r700 command stream checker
This patch add cs checker to r600/r700 hw. Command stream checking
will rewrite some of the cs value in order to restrict GPU access
to BO size. This doesn't break old userspace but just enforce safe
value. It should break any things that was using the r600/r700 cs
ioctl to do forbidden things (malicious software), though we are
not aware of such things.

Here is the list of thing we check :
- enforcing resource size
- enforcing color buffer slice tile max, will restrict cb access
- enforcing db buffer slice tile max, will restrict db access

We don't check for shader bigger than the BO in which they are
supposed to be, such use would lead to GPU lockup and is harmless
from security POV, as far as we can tell (note that even checking
for this wouldn't prevent someone to write bogus shader that lead
to lockup).

This patch has received as much testing as humanly possible with
old userspace to check that it didn't break such configuration.
However not all the applications out there were tested, thus it
might broke some odd, rare applications.

551ebd837c drm/radeon/kms: add rn50/r100/r200 CS tracker.
This adds the command stream checker for the RN50, R100 and R200 cards.

It stops any access to 3D registers on RN50, and does checks
on buffer sizes on the r100/r200 cards. It also fixes some texture
sizing checks on r300.

Previously we just made these offline and included them,
but no reason we can't generate them at build time.

TODO: add rs690 + r100/r200 when done.
should we do rs480/rs690 no tcl version?
