* printf: Convert %T to %pTEvan Green2019-10-051-1/+2
| | | | | | | | | | | | | | | | | | | | | | 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.

* i2c: Split i2c_xfer into locked/unlocked versions.Jonathan Brandmeyer2018-08-161-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rename i2c_xfer to i2c_xfer_unlocked. Audit all users of i2c_xfer to see if they can use simple locking semantics or require their own locking. Since locked accesses are only safe for I2C_XFER_SINGLE transactions, remove the flags parameter from i2c_xfer. This also makes the audit a bit easier. Some remaining applications hold the bus locked across several transactions that would otherwise be atomic, and a few others implement complex I2C transactions in multiple commands. Add a (nondeterministic) verification on the I2C port locking correctness. This will catch all statically incorrect locking patterns, although dynamically incorrect locking patterns may not be caught. Related: Revise the i2c_port_active_count to be a bitmap of the active ports instead of a count of the active ports. The EC's mutex does not provide an is_locked() primitive, and we would prefer not to have one. - board/glados: Custom locking for battery reset - board/mchpevb1: Custom locking for battery reset - board/oak: Custom locking for battery reset - board/samus: Custom locking for lightbar reset - board/sweetberry: simple locking - board/servo_micro: Custom locking for funky i2c transfers - capsense: simple locking - host_command_master: multi-command transactions - lb_common: manual locking to support samus power sequence - smbus: multi-command transactions - usb_i2c: simple locking - driver/tcpm/fusb302: simple locking and multi-command transactions - driver/tcpm/tcpi: Forward _unlocked and implicitly locked interface to fusb302 - driver/touchpad_elan: simple locking BUG=chromium:871851 BRANCH=none TEST=buildall; very careful audit TEST=grunt clamshell and Coral clamshell, test boot, battery charging, PD communication, and TCPC port low-power mode.

* Deferred: Use deferred_data instead of function pointerAnton Staaf2016-04-181-2/+2
| | | | | | | | | | | | | | | | | | | | | Previously calls to hook_call_deferred were passed the function to call, which was then looked up in the .rodata.deferred section with a linear search. This linear search can be replaced with a subtract by passing the pointer to the deferred_data object created when DECLARE_DEFERRED was invoked.

* Add cprints() and ccprints()Vic Yang2014-05-211-1/+2
| | | | | | | | | | | | | | | | | | | | | Our code base contains a lot of debug messages in this pattern: CPRINTF("[%T xxx]\n") or ccprintf("[%T xxx]\n") The strings are taking up spaces in the EC binaries, so let's refactor this by adding cprints() and ccprints(). cprints() is just like cprintf(), except that it adds the brackets and the timestamp. ccprints() is equivalent to cprints(CC_CONSOLE, ...) This saves us hundreds of bytes in EC binaries.

* Samus: Support capsense input as keyboard events.Bill Richardson2014-02-081-0/+86
This is experimental for now; the capsense chip simply reports its buttons as the number keys on the keyboard (1-8). BUG=chrome-os-partner:23382 BRANCH=samus,ToT TEST=manual To test, you'll need a reworked and correctly programmed capsense module. Boot the system, and switch to VT2. Touch the capsense bar and you'll see the input appear on the console as though you were typing numbers. Note that the capsense hardware is still buggy. Refer to the bug for workarounds.
