• 803a4e14a   uvesafb,vesafb: create WC or WB PAT-entries ... Browse Code »

  with an PAT-enabled kernel, when using uvesafb or vesafb, these drivers will
  create uncached-minus PAT entries for the framebuffer memory because they use
  ioremap() (not the *_cache or *_wc variants). When the framebuffer memory
  intersects with the video RAM used by Xorg, the complete video RAM will be
  mapped uncached-minus what results in a serve performance penalty.

  Here are the correct MTRR entries created by uvesafb:
  schlicht@netbook:~$ cat /proc/mtrr
  reg00: base=0x000000000 ( 0MB), size= 2048MB, count=1: write-back
  reg01: base=0x06ff00000 ( 1791MB), size= 1MB, count=1: uncachable
  reg02: base=0x070000000 ( 1792MB), size= 256MB, count=1: uncachable
  reg03: base=0x0d0000000 ( 3328MB), size= 16MB, count=1: write-combining

  And here are the problematic PAT entries:
  schlicht@netbook:~$ sudo cat /sys/kernel/debug/x86/pat_memtype_list
  PAT memtype list:
  write-back @ 0x0-0x1000
  uncached-minus @ 0x6fedd000-0x6fee3000
  uncached-minus @ 0x6fee2000-0x6fee3000

  Current implementation calls of_iounmap for par->fbc twice in error path.
  In the case of goto out_unmap_dac, we should call of_iounmap for par->dac.

• 49bb09433   radeonfb: Let hwmon driver probe the "monid" I2C bus ... Browse Code »

  Some Radeon cards have an I2C-based thermal sensor chip connected to
  the "monid" I2C bus. Set the I2C probing class of this bus properly so
  that hwmon drivers can detect devices on it and bind to them.

  This closes kernel.org bug #26172.

  We exclude PPC for the time being, as Benjamin doesn't want us to
  mess up with them without explicit testing, and there is no evidence
  that this change is needed for them either.

  Use "new" start address register 0x69 (bits 16-20) instead of "old" 0x31
  (bits 16-17) and 0x51 (bits 18-19). This is needed for panning to work
  correctly on Trio3D/2X cards (and does no harm on other ones).
