I've gathered up the various outstanding radeon patches and put them up in a tree for testing: http://cgit.freedesktop.org/~agd5f/linux/log/?h=drm-next-3.7-wip Some of these may end up in -fixes, but most of them are -next material. I haven't had a chance to go through Christian's last set of VM patches yet.
Highlights:
- rom fetch fixes (UEFI, thunderbolt docks)
- major ACPI rework
- backlight control for newer asics
Hi Alex, I just tested the rebased acpi_patches branch: ACPI part works fine, but I see a big slow down during radeon driver initialization when the screen goes black for a couple of seconds (with 3.5.0 + acpi patches the screen just flickers during boot). With initcall_debug I see:
[ 2.355300] calling radeon_init+0x0/0x1000 [radeon] @ 552 ... [ 5.530310] initcall radeon_init+0x0/0x1000 [radeon] returned 0 after 3102147 usecs
For reference 3.5 takes ~1 sec. With drm.debug=2 the log (attached) is not very informative, I'll try and get more info...
