2013-11-26Log device path into CMOS during probe stagesDuncan Laurie
One of the most common hangs during coreboot execution is during ramstage device init steps. Currently there are a set of (somewhat misleading) post codes during this phase which give some indication as to where execution stopped, but it provides no information on what device was actually being initialized at that point. This uses the new CMOS "extra" log banks to store the encoded device path of the device that is about to be touched by coreboot. This way if the system hangs when talking to the device there will be some indication where to investigate next. interrupted boot with reset button and gathered the eventlog after several test runs: 26 | 2013-06-10 10:32:48 | System boot | 120 27 | 2013-06-10 10:32:48 | Last post code in previous boot | 0x75 | Device Initialize 28 | 2013-06-10 10:32:48 | Extra info from previous boot | PCI | 00:16.0 29 | 2013-06-10 10:32:48 | Reset Button 30 | 2013-06-10 10:32:48 | System Reset Change-Id: I6045bd4c384358b8a4e464eb03ccad639283939c Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/58105 Reviewed-on: http://review.coreboot.org/4230 Tested-by: build bot (Jenkins) Reviewed-by: Alexandru Gagniuc <mr.nuke.me@gmail.com>
2013-11-26Extend CMOS POST code logging to store extra dataDuncan Laurie
This can be used to indicate sub-state within a POST code range which can assist in debugging BIOS hangs. For example this can be used to indicate which device is about to be initialized so if the system hangs while talking to that device it can be identified.

2013-11-26cmos post: Guard with spinlockDuncan Laurie
The CMOS post code storage mechanism does back-to-back CMOS reads and writes that may be interleaved during CPU bringup, leading to corruption of the log or of other parts of CMOS.

2012-11-27Make POST codes written to IO port optionalDavid Hendricks
This adds more configurability to POST codes. The current assumption is that POST codes should be written to an IO port (e.g. LPC) if POST codes are enabled. This changes the assumption so that POST codes can be written to the serial console without being written to an IO port. This enables POST codes by default using "default y" to avoid changing current behavior.

This will use 3 bytes of CMOS to keep track of the POST code for the current boot while also leaving a record of the previous boot. The active bank is switched early in the bootblock. Test: 1) clear cmos 2) reboot 3) use "mosys nvram dump" to verify that the first byte contains 0x80 and the second byte contains 0xF8 4) powerd_suspend and then resume 5) use "mosys nvram dump" to verify that the first byte contains 0x81 and the second byte contains 0xFD Change-Id: I1ee6bb2dac053018f3042ab5a0b26c435dbfd151 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1743 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
2012-08-04Add a capability for mainboard-specific posting.Alexandru Gagniuc
Some mainboards have really nice capabilities for posting, beyond simple POST cards. Further, some can not use a POST card. This change defines a weak symbol (mainboard_post) that can be overridden by a real mainboard_post function. If, for example, you'd like to do something fancy before the payload starts, you can add this to mainboard.c: void mainboard_post(u8 value) { switch(value){ case POST_TIME_TO_PARTY: some_fancy_lights(); break; } } Maybe the post function should be an entry in the device. We're beginning to over-use weak symbols. BUG=None TEST=Build and boot a google chromebook. Observe that it still works. Use it to drive some pretty lights.

2010-11-22Printing coreboot debug messages on VGA console is pretty much useless, sinceStefan Reinauer
initializing VGA happens pretty much as the last thing before starting the payload. Hence, drop VGA console support, as we did in coreboot v3. - Drop VGA and BTEXT console support. Console is meant to be debugging only, and by the time graphics comes up 99% of the risky stuff has already happened. Note: This patch does not remove hardware init but only the actual output functionality. The ragexl driver needs some extra love, but that's for another day - factor out die() and post() - drop some leftover RAMBASE < 0x100000 checks.
