Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[SCSI] a100u2w: Convert into Linux style I was investigating strange driver behaviour and thought that readable code and proper visible types might help explain why it didn't work right the moment a second SCB was outstanding to the controller. I was right - Cleanup, linuxise, demacro - Remove the BSD dual licence on the new work - Switch the if ALPHA to if __LP64__. (struct size is then right elsewhere) and then to CONFIG_64BIT as per Christoph's request - Fix the recursive locking on a reset. This is the only actual real code change (I hope ;)). I'm not clear what the right way to handle the BIOS param stuff is on n on x86-32/64. Using phys_to_virt and stuff is ugly and probably doesn't make sense elsewhere Still has a couple of odd things - and there seems to be a commonly shared EEPROM handling error several drivers have. Roughly speaking several SCSI drivers go try and read EEPROM It failed.. Write any changes between the default and the data we read Which is great as for some paths we've no idea what was in before, so each boot won't write it all back, won't checksum but will repeat the bug Also it can still sleep for a second with IRQ off, and there is some dubious looking error path locking marked FIXME in case anyone feels inspired to work on it. Not a newly introduced bug, and at least its now marked. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

(struct size is then right elsewhere) and then to CONFIG_64BIT as per Christoph's request - Fix the recursive locking on a reset. This is the only actual real code change (I hope ;)). I'm not clear what the right way to handle the BIOS param stuff is on n on x86-32/64.

Roughly speaking several SCSI drivers go try and read EEPROM It failed.. Write any changes between the default and the data we read Which is great as for some paths we've no idea what was in before, so each boot won't write it all back, won't checksum but will repeat the bug Also it can still sleep for a second with IRQ off, and there is some dubious looking error path locking marked FIXME in case anyone feels inspired to work on it.
