The developer "stepan" checked in revision 2587 to
the LinuxBIOS source repository and caused the following
changes:
Change Log:
This patch makes sure that VGA is initialized before it is used. Without
this fix, LinuxBIOS crashes if the CONSOLE_LOG_LEVEL is high enough.
Build Log:
Compilation of artecgroup:dbe61 has been broken
Compilation of technologic:ts5300 has been broken
The patch was wrong. It was taken from here:
http://www.linuxbios.org/pipermail/linuxbios/2007-February/018257.html
This patch does not initialize VGA when CONFIG_CONSOLE_VGA==0 and
CONFIG_PCI_ROM_RUN==1.
The patch should have been taken from here:
http://www.linuxbios.org/pipermail/linuxbios/2007-February/018284.html
The attached patch corrects the head revision.
I tried to build the broken compilations using the default procedure
"buildtarget && make -C <directory>" and I am confused:
1.
~/linuxbios/targets>./buildtarget technologic/ts5300/Config.lb && make
-C technologic/ts5300/technologic_ts5300
completes without an error for both r2586 and r2587 (dies looking for
the payload).
2.
~/linuxbios/targets>./buildtarget technologic/ts5300/Config-abuild.lb
gives
===> ERROR: Option __COMPRESSION__ undefined (missing use command?)
for both r2586 and r2587.
I conclude that it brakes for unrelated reasons.
Regargs,
Roman
This patch corrects r2587. It makes sure that the VGA is initialized
when CONFIG_CONSOLE_VGA==0 and CONFIG_PCI_ROM_RUN==1
