* port80: Add a config to avoid logging port80 codesAndrew McRae2022-08-251-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Add a config item to disable logging all of the port80 history buffer as each code is received. Individual codes can still be logged as they are received when enabled via the console command 'port80 intprint' or using the CONFIG_PORT80_PRINT_IN_INT config item. This reduces the overhead at AP startup on the logging. It has been observed on the ITE81302 that logging the port80 codes causes significant overhead that may lead to watchdog timeouts. The port80 code history is still available via the 'port80' EC console command.

| | | | | | | | | | | | | | | | | | | | | | In order to be more compliant to standards, and ultimately turn on compile-time printf format validation, switch the non-standard %T into %pT, which takes a pointer to a 64-bit timestamp as an argument. For convenience, define PRINTF_TIMESTAMP_NOW, which will use the current time as the timestamp value, rather than forcing everyone to pass a pointer to get_time().val. For a couple of instances, simply use CPRINTS instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the host command handler callback function returns an int, it's easy to accidentally mix up the enum ec_error_list and enum ec_status types.

* Better help for console commandsRandall Spangler2012-05-251-1/+4
| | | | | | | | | | | | | | | | | | | | Additional help messages and usage are gated by CONFIG_CONSOLE_CMDHELP, so we can turn it on if there's space (adds about 3KB to image size) and turn it off when there isn't.

* Even more debug command cleanup to save spaceRandall Spangler2012-05-211-7/+5
| | | | | | | | BUG=none TEST=(run the commands) Change-Id: Ibc414ffd594e06dbdce64c51859b6f247bb10d36 Signed-off-by: Randall Spangler <rspangler@chromium.org>
* Use console output instead of uart output for console commandsRandall Spangler2012-04-241-1/+1
| | | | | | | | | | | | This completes console output cleanup. The remaining calls to uart_puts() and uart_printf() actually need to be that way. Signed-off-by: Randall Spangler <rspangler@chromium.org> BUG=chrome-os-partner:7464 TEST=manual Change-Id: Ib1d6d370d30429017b3d11994894fece75fab6ea
* Refactor async console outputRandall Spangler2012-04-241-6/+7
| | | | | | | | | | | | | | | | | | This adds a 'ch' command which prints/sets which channels are active This handles all the async output; the remaining debug commands will be refactored to use ccprintf() / ccputs() in a followup CL. Signed-off-by: Randall Spangler <rspangler@chromium.org> BUG=chrome-os-partner:7464 TEST=manual ch --> all channels active ch 0x100 -> just port80 active powerbtn -> system boots; only port 80 codes shown on console Change-Id: I9efc43acec919b62b78c2c82c61946d32380adfe
* Clean up initsRandall Spangler2012-04-191-12/+2
| | | | | | | | | | | | We can clear the reset cause in system pre-init now because of a previous change which preserves it across a sysjump. Signed-off-by: Randall Spangler <rspangler@chromium.org> BUG=none TEST=if it boots, it works Change-Id: I1d8b99df5a0be0de9545d22ad1a6b7fb3140f813

| | | | | | | | | Signed-off-by: Randall Spangler <rspangler@chromium.org> BUG=chrome-os-partner:8724 TEST=if timestamps show up in the debug output, it works Change-Id: I5264a3a40a07a824cc15b39a7bd81f2db02a3c13
* Remove code for skipping duplicate port 80 writesRandall Spangler2012-03-191-13/+4
| | | | | | | | | | | | | The kernel no longer uses port 80 as a delay mechanism, so we don't need to detect the no-longer-present spammy writes. Signed-off-by: Randall Spangler <rspangler@chromium.org> BUG=chrome-os-partner:7972 TEST=port80 scroll, then boot the system. see a few repeated bytes, but not piles of 00 and ff's. Change-Id: Id14dc43ab4e1b15c6bab99a17c062f295a59e7e6
* Make port 80 output less scrollyRandall Spangler2012-02-141-7/+16
| | | | | | | | | | | | | | | | | | | | | It was scrolling so much that the EC debug output for power state transitions was getting lost. Now it uses CR instead of LF. Use 'port80 scroll' to turn scrolling back on (it's off by default). Port 80 history is still visible via the 'port80' command, in all cases. Signed-off-by: Randall Spangler <rspangler@chromium.org> BUG=none TEST=powerbtn ; power on; should not scroll screen port80 ; confirm history is still there port80 scroll ; enable scrolling powerbtn ; turn system off powerbtn ; turn system back on; should scroll screen port80 ; confirm history is still there Change-Id: I85d058ff0b2b9d3d5296060747bde5e872b85817
* Print repeated port 80 writes, for coreboot/uboot debuggingRandall Spangler2012-02-091-0/+3

* register console commands at compile-timeVincent Palatin2012-01-241-9/+1
| | | | | | | | | | | | | | | Instead of using a runtime callback to register the console commands, put them in a special linker section. So we can do a macro to "register" them during the build. It saves 684 bytes and a few microseconds at startup. Signed-off-by: Vincent Palatin <vpalatin@chromium.org> BUG=None TEST=run a few commands from the BDS command line.
