* drm/nouveau: Parse old style perf tables.Francisco Jerez2010-09-242-4/+53
| | | | | | | | | | | | | Used on nv17-nv28, they contain memory clocks and timings, only one of the table entries can actually be used, depending on the RAMCFG straps, and it's usually higher than the frequency programmed on boot by the BIOS. The memory timings listed in table version 0x1x are used to init the 0x12xx range but they aren't required for reclocking to work.

Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Acked-by: Matthew Garrett <mjg@redhat.com> It doesn't seem to revert cleanly, but the problem lies in these two config entries: CONFIG_ACPI=y CONFIG_ACPI_VIDEO=m Adding a select for ACPI_VIDEO appears to be the best solution, and is comparable to what is done in DRM_I915. Builds, boots, and appears to work correctly. Signed-off-by: Philip J. Turmel <philip@turmel.org> Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nv04-nv40: import initial pm backendBen Skeggs2010-09-245-3/+110
| | | | | | | | | | Currently just hooked up to the already-existing nouveau_hw, which should handle all relevant chipsets as well as we currently can. This will likely be eventually split out and improved into chipset specific code at a later point. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nv50: import initial clock get/set routines + hook up pm engineBen Skeggs2010-09-244-1/+138
| | | | | | | | | This will make nouveau_pm attempt to report the card's current performance level both during bootup, and through sysfs. This is a very initial implementation, and can be improved a *lot* Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau: make the behaviour of get_pll_limits() consistentBen Skeggs2010-09-246-59/+135
| | | | | | | | | | | This replaces all the pll_types definitions for ones that match the types used in the tables in recent VBIOS versions. get_pll_limits() will now accept either type or register value as input across all limits table versions, and will store the actual register ID that a PLL type refers to in the returned structure.

* drm/nouveau: we can't free ACPI EDID, so make a copy that we canBen Skeggs2010-09-241-1/+1
| | | | | | | | The rest of the connector code assumes we can kfree() the EDID pointer. This causes things to blow up with the ACPI EDID pointer we get passed. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau: handle fifo pusher errors betterBen Skeggs2010-09-241-8/+37
| | | | | | | | | | | | The most important part of this change is that we now instruct PFIFO to drop all pending fetches, rather than attempting to skip a single dword and hope that things would magically sort themselves out - they usually don't, and we end up with PFIFO being completely hung. This commit also adds somewhat more useful logging when these exceptions occur. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau: Simplify tile region handling.Francisco Jerez2010-09-246-60/+36
| | | | | | | | | Instead of emptying the caches to avoid a race with the PFIFO puller, go straight ahead and try to recover from it when it happens. Also, kill pfifo->cache_flush and tile->lock, we don't need them anymore. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau: protect ramht_find() from oopsing if on channel without ramhtBen Skeggs2010-09-241-0/+3
| | | | | | | | | | | This doesn't actually happen now, but there's a test case for an earlier kernel where a GPU error is signalled on one of nv50's fake channels, and the ramht lookup by the IRQ handler triggered an oops. This adds a check for RAMHT's existance on a channel before looking up an object handle. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
