From cd84b8de7664c3b278310c558521f8e94e3128e0 Mon Sep 17 00:00:00 2001 From: Peter Stuge Date: Sun, 11 Dec 2022 04:02:10 +0100 Subject: serial: Call set_custom_baudrate() thrice Call the function before tcsetattr() settings are known, then again with settings prepared but not yet applied and finally a third time after tcsetattr(). Darwin support needs this change; there custom_baud code must be called to modify the settings passed to tcsetattr() and then again after tcsetattr() returns. The change should be non-functional on all currently supported systems; current code calls set_custom_baudrate() before any tcsetattr() settings are prepared, so we have three stages in total. This change originates from discussion of the macOS patch proposed by Denis Ahrens in https://review.coreboot.org/c/flashrom/+/67822 Change-Id: I40cc443cfb7bf6b212b31826d437b898cc13c427 Signed-off-by: Peter Stuge Reviewed-on: https://review.coreboot.org/c/flashrom/+/70569 Tested-by: build bot (Jenkins) Reviewed-by: Thomas Heijligen --- include/custom_baud.h | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'include') diff --git a/include/custom_baud.h b/include/custom_baud.h index c8b8fc29..38e6cfc4 100644 --- a/include/custom_baud.h +++ b/include/custom_baud.h @@ -22,7 +22,13 @@ struct baudentry { unsigned int baud; }; -int set_custom_baudrate(int fd, unsigned int baud); +enum custom_baud_stage { + BEFORE_FLAGS = 0, + WITH_FLAGS, + AFTER_FLAGS +}; + +int set_custom_baudrate(int fd, unsigned int baud, const enum custom_baud_stage stage, void *tio_wanted); /* Returns 1 if non-exact rate would be used, and setting a custom rate is supported.
