I'm not sure I understand the intent of the previous behavior.  mmap

would be fully cacheable.  But the DRM code (most of the time) would
add a write-combining MTRR that would change the effective memory
type to WC.

The new behavior just requests WC explicitly for all AGP maps.

If there is any code out there that expects cacheable access to the
AGP aperture (because the drm driver doesn't request an MTRR or
because it's using /dev/agpgart directly), then it will now end up
with a UC or WC mapping, depending on the architecture and PAT
availability.  But cacheable access to the aperture seems like it's
asking for trouble, because, AIUI, the aperture is an alias of RAM.

ioremap_wc, etc) are working.

arch_phys_wc_add and arch_phys_wc_del are new functions, available

also easier to use than mtrr_add and mtrr_del, so the call sites can

radeon: use max_bus_speed to activate gen2 speeds

radeon currently uses a drm function to get the speed capabilities for
the bus, drm_pcie_get_speed_cap_mask. However, this is a non-standard
method of performing this detection and this patch changes it to use
the max_bus_speed attribute.

drm/radeon: narrow scope of Apple re-POST hack

This narrows the scope of the apple re-POST hack added in:
drm/radeon: re-POST the asic on Apple hardware when booted via EFI

That patch prevents UVD from working on macs when booted in EFI
mode.  The original patch fixed macbook2,1 systems which were
r5xx and hence have no UVD.  Limit the hack to those systems to
prevent UVD breakage on newer systems.

11 years agodrm/i915: force full modeset if the connector is in DPMS OFF mode

drm/i915: force full modeset if the connector is in DPMS OFF mode

Currently the driver's assumed behavior for a modeset with an attached
FB is that the corresponding connector will be switched to DPMS ON mode
if it happened to be in DPMS OFF (or another power save mode). This
wasn't enforced though if only the FB changed, everything else (format,
connector etc.) remaining the same. In this case we only set the new FB
base and left the connector in the old power save mode.

Fix this by forcing a full modeset whenever there is an attached FB and
any affected connector is in a power save mode.

V_2: Run the test for encoders in power save mode outside the the
test for fb change: user space may have just disabled the encoders
but left everything else in place. Make sure the connector list is
not empty before running this test.

local_irq_enable() may expand into very different code, so it rather should
stay in C.  Also this keeps the assembler code size constant which keeps
the rollback code simple.  So it's best to split r4k_wait into two parts,
one C and one assembler.

Finally add the local_irq_enable() to r4k_wait to ensure the WAIT
