* drm/ttm: introduce utility function to free an allocated memory nodeBen Skeggs2010-10-04
| | | | | | | | | | Existing core code/drivers call drm_mm_put_block on ttm_mem_reg.mm_node directly. Future patches will modify TTM behaviour in such a way that ttm_mem_reg.mm_node doesn't necessarily belong to drm_mm.

* drm/nouveau: parse voltage from perf 0x40 entiresBen Skeggs2010-10-04
| | | | | | | This was disabled previously because of some uncertainty that +2 was indeed the voltage. It appears it is, checked on a NVA8 and a NVA3M. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau: fix required mode bandwidth calculation for DPBen Skeggs2010-10-04
| | | | | | | | This should fix eDP on certain laptops with 18-bit panels, we were rejecting the panel's native mode due to thinking there was insufficient bandwidth for it. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| | | | | | | | | | | | | | This isn't correct everywhere yet, but since we don't use the data yet it's perfectly safe to push in, and the information we gain from logs will help to fix the remaining issues. v2 (Ben Skeggs <bskeggs@redhat.com>): - fixed up formatting - free parsed timing info on takedown - switched timing table printout to debug loglevel Signed-off-by: Roy Spliet <r.spliet@student.tudelft.nl> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nv50: use pll type rather than register for CRTC PLLBen Skeggs2010-09-24

* drm/nouveau: fix panels using straps-based mode detectionBen Skeggs2010-09-24
| | | | | | | | nouveau_bios_fp_mode() zeroes the mode struct before filling in relevant entries. This nukes the mode id initialised by drm_mode_create(), and causes warnings from idr when we try to remove the mode. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau: Parse old style perf tables.Francisco Jerez2010-09-24
| | | | | | | | | | | | | 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.
