As there is this thread about mtrr on Intel chipsets, I have some
messages in the log about mtrr, and I don't know whether they are
harmless warnings or errors that should be reported.
My computer is a 2.4 GhZ Pentium IV with an intel i845G/GL chipset.
Motherboard and bios by shuttle.
$ cat /proc/mtrr
reg00: base=0x00000000 ( 0MB), size= 512MB: write-back, count=1
reg01: base=0x1f800000 ( 504MB), size= 8MB: uncachable, count=1
reg02: base=0xe0000000 (3584MB), size= 128MB: write-combining, count=2
I have 512 MB of memory, the motherboard doesn't support more than 2GB
and I don't see what is this range over 3.5 GB. Also, the two first
overlaping ranges look suspicious.
I have the following error/warning messages in the log:
* with kernel 2.4.21pre3 (+ acpi patches)
mtrr: base(0xe0020000) is not aligned on a size(0x800000)
boundary
(this happens just after initializing drm)
* with kernel 2.5.63 (+ acpi patches)
mtrr: MTRR 2 not used
(this happens once or twice during each sutdown. Note that I don't have
drm with kernel 2.5.x, so I don't know if the first message is really
gone)
So... Is this situation normal ?
