Subject: Out of mtrrs
Hi all...
I'm using the xorg intel driver, and drm/X report it has no free mtrrs
in kernel to set up:
one:~# cat /proc/mtrr
reg00: base=0xfffe0000 (4095MB), size= 128KB: write-protect, count=1
reg01: base=0xfffc0000 (4095MB), size= 128KB: uncachable, count=1
reg02: base=0x00000000 ( 0MB), size= 256MB: write-back, count=1
reg03: base=0x10000000 ( 256MB), size= 256MB: write-back, count=1
reg04: base=0x1f800000 ( 504MB), size= 8MB: uncachable, count=1
reg05: base=0x1f600000 ( 502MB), size= 2MB: uncachable, count=1
reg06: base=0x1f500000 ( 501MB), size= 1MB: uncachable, count=1
reg07: base=0x00000000 ( 0MB), size= 128KB: uncachable, count=1
dmesg:
[drm] Initialized i915 1.6.0 20060119 on minor 0
mtrr: no more MTRRs available
one:/var/log# grep Linear x.log
(--) intel(0): Linear framebuffer at 0x20000000
I think X tries to get a mtrr at 0x20000000, but kernel has no free one
to offer.
Does this have any solution ?
TIA
(Oh, this is 2.6.26.3, intel driver 2.4.2)
