- I did the port to the M4A785T-M
- I've an x60
- I've an alix.1C
scripts to help getting rid of the vbios of the x60
Script 1: generate the io access for the coreboot driver
- follow "Case study: new laptop (not complete, sorry)" in https://docs.google.com/document/d/1g8FMob25VZYxbWri2iFB8YiSL8gwF9vKJH3HGxr0xQU/edit?pli=1
- pacman -S plan9port
- cp /opt/plan9/bin/ssam ./
- replace the following line in ./ssam:
#!/usr/local/plan9/bin/rc
by the following line:
#!/opt/plan9/bin/rc
- create the ssamfix file with:
,s/\[ *[0-9]+\..[0-9]+\]//g
,s/^ *//g
y/^[RWU]/s/^/M /g
,s/\nU/ ;;;UDELAY/g
,|uniq -c
,s/^ *//g
,s/(^[0-9]+) ([MRW])/\2 \1/g
,s/"/\\"/g
,s/^M ([0-9]+) *(\[.*)/{M, \1, "\2"},/g
,s/^M ([0-9]+) *(.*)/{M, \1, "\2"},/g
,s/: */:/g
,s/...UDELAY *([0-9]+)/\1/g
,s/^([RW]) ([0-9]+) (.*):0x([0-9a-f]+)(.*)/{\1, \2, "", \3, 0x\4, \5},/g
- run the following commands:
. /etc/profile.d/plan9.sh cat dmesg| ./ssam -f ssamfix > foo.c
Script2: compare the io access that were too fast
- Replace {V,0,}, with {V,7,}, in src/mainboard/vendor/device/i915io.c
- cat /dev/ttyUSB0 > accesses.txt
- Use that script against accesses.txt to find the guilty accesses:
#!/usr/bin/env python2
import sys,re
def main(args):
try:
f = open(args[1],'ro')
except:
print args[0], " <file>"
for line in f:
if re.match("0x[0-9]*: Got .*, expect .*",line):
line = line.replace('\r\n',).replace(", expect ",':').replace(": Got ",':')
split = line.split(':')
#print split
if split[1] != split[2]:
print line
if __name__ == '__main__':
main(sys.argv)
