Hi,
does anyone know what and if this is a normal message or if indeed it is something to be fixed?
| Code: |
bash-2.05b# dmesg | grep mtrr
mtrr: v2.0 (20020519)
mtrr: base(0xf0020000) is not aligned on a size(0x300000) boundary
mtrr: base(0xf0020000) is not aligned on a size(0x300000) boundary
|
This is what I have:
| Code: |
bash-2.05b# cat /proc/mtrr
reg00: base=0x00000000 ( 0MB), size= 512MB: write-back, count=1
reg01: base=0xf0000000 (3840MB), size= 128MB: write-combining, count=3
bash-2.05b# dmesg | grep vesafb
Kernel command line: ro root=/dev/hda4 video=vesafb:ywrap,pmipal,1024x768-32@85 splash=silent,theme:emergence
vesafb: Intel Corporation, Intel(r)865G Graphics Controller, Hardware Version 0.0 (OEM: Intel(r)865G Graphics Chip Accelerated VGA BIOS)
vesafb: VBE version: 3.0
vesafb: hardware supports DCC2 transfers
vesafb: monitor limits: vf = 85 Hz, hf = 70 kHz, clk = 100 MHz
vesafb: scrolling: redraw
vesafb: framebuffer at 0xf0000000, mapped to 0xdf980000, size 16192k

Also, because I have an Intel B865GLCL motherboard with an integrated video card, which I think it does not have any memory but it uses the RAM memory, what is the command that I should type to learn exactely what and how much memory the video card has, so that I can also add it to the xorg.conf file?
Here is my lspci -v
| Code: |
bash-2.05b# lspci -v
0000:00:02.0 VGA compatible controller: Intel Corp. 82865G Integrated GraphicsDevice (rev 02) (prog-if 00 [VGA])
Subsystem: Intel Corp.: Unknown device 4c43
Flags: bus master, fast devsel, latency 0, IRQ 11
Memory at f0000000 (32-bit, prefetchable)
Memory at ffa00000 (32-bit, non-prefetchable) [size=512K]
I/O ports at ec00 [size=8]
Capabilities: [d0] Power Management version 1

I get the same message from MTRR, too (I have an ancient Intel 810e chipset - same principle). I've had it right from the beginning. Can be safely ignored, I suppose, but it'd be good to know what it is.
Anyway, to check how much video RAM you've got out of system RAM, see your XFree86.0.log or Xorg.0.log as the case might be. Look for a line that looks something like:
| Code: | (--) I810(0): Chipset: "i810e"
(--) I810(0): Linear framebuffer at 0x44000000
(--) I810(0): IO registers at addr 0x40100000
(II) I810(0): I810CheckAvailableMemory: 152572k available
(**) I810(0): Will alloc AGP framebuffer: 16384 kByte |
I tweak this memory like so (in XF86Config or xorg.conf):
| Code: | Section "Device"
Identifier "Intel 810"
Driver "i810"
VideoRam 16384
EndSection |
