Does this mean to use the data from pci command output result?
0.2.0: vid 03.00.00 8086/29a2 10 0:fde00000 1048576 2:d000000c 268435456 4:0000ff01 16
In my case, use ff01 and ff05 instead of 1804 and 1805 in mmio.awk?
I used those value, and got all ffffffff value like:
rmmio 00041000 ffffffff #
rmmio 00044008 ffffffff #
rmmio 0004f000 ffffffff #
rmmio 0004f040 ffffffff #
rmmio 0004f044 ffffffff #
rmmio 0004f048 ffffffff #
rmmio 0004f04c ffffffff #
rmmio 00060000 ffffffff # HTOTAL_A
rmmio 00060004 ffffffff # HBLANK_A
rmmio 00060008 ffffffff # HSYNC_A
rmmio 0006000c ffffffff # VTOTAL_A
rmmio 00060010 ffffffff # VBLANK_A
rmmio 00060014 ffffffff # VSYNC_A
rmmio 0006001c ffffffff # PIPEASRC
I suppose we should compare the two dumps, one from vesa
using aux/realemu, which I got success like:
rport 03d4 0f # VGA_CRX
rport 03d6 ff #
rport 03d0 ff #
rport 03ce 06 # VGA_GRX
rport 03d2 ff #
rport 03c4 01 # VGA_SRX
rport 03c7 00 # VGA_DACSTATE/DACRX
rport 03c8 40 # VGA_DACWX
wport ff00 00002020 #
rport ff04 cff80001 #
wport ff00 00071414 #
