Tue, 16 Aug 2022 11:57:32 +0000

tty: Remove baudrate dead code & make ktermios params constWith the architectures currently in-tree, either: 1) CBAUDEX is zero 2) The earlier BOTHER if check covers cbaud < 1 case 3) All CBAUD bits are covered by the baud_tableThus, the check for cbaud being out-of-range for CBAUDEX case cannotever be true.The ktermios parameters can now be made const.Reviewed-by: Andy Shevchenko Signed-off-by: Ilpo Järvinen Link: https://lore.kernel.org/r/20220816115739.10928-2-ilpo.jarvinen@linux.intel.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/tty/tty_baudrate.c

Mon, 27 Sep 2021 13:35:16 +0000

tty: baudrate: Explicit usage of B0 for encoding input baudrateFunction tty_termios_input_baud_rate() checks IBSHIFT & CBAUD against B0constant to determinate if input speed equals to output speed. So do sameB0 check also in tty_termios_encode_baud_rate() function to make these twofunctions compatible.Currently macro B0 is defined to 0 so there is no functional change.This change just make code more explicit to show that Bnnn constants arestored in CBAUD.Signed-off-by: Pali Rohár Link: https://lore.kernel.org/r/20210927133516.8671-1-pali@kernel.orgSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/tty/tty_baudrate.c

tty: fix kernel-docWith W=1, the kernel-doc checker complains quite a lot in the tty layer.Over the time, many documented parameters were renamed, removed orswitched from tty to tty_port and similar. Some were mistyped in the doctoo.So fix all these in the tty core. (But do not add the missing ones whichthe checker complains about too. Not now.)

fefe287e - tty: support CIBAUD without BOTHER

Sun, 15 Jul 2018 13:39:35 +0000

tty: support CIBAUD without BOTHERSince commit edc6afc54968 ("[PATCH] tty: switch to ktermios and newframework") arbitrary baud rates can be requested using BOTHER and inputrates can be requested using the termios CIBAUD bits (CBAUD shiftedIBSHIFT bits).This functionality has been conditionally compiled depending on whetheran architecture defines BOTHER and IBSHIFT respectively, but would infact fail to compile unless both symbols were defined due to crossdependencies.Relax the IBSHIFT => BOTHER dependency so that an architecture couldtheoretically support CIBAUD without the Linux-specific BOTHER, whilehopefully making the current conditional-compilation directives a bitless confusing.Note that the long-term goal is still to have all architectures supportboth features, so an alternative could just be to have the lot depend onBOTHER.Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/tty/tty_baudrate.c

1cee38f0 - tty: fix termios input-speed encoding when using BOTHER

Sun, 15 Jul 2018 13:39:34 +0000

tty: fix termios input-speed encoding when using BOTHERWhen the termios CIBAUD bits are left unset (i.e. B0), we use the sameoutput and input speed and should leave CIBAUD unchanged.When the user requests a rate using BOTHER and c_ospeed which the drivercannot set exactly, the driver can report back the actual baud rateusing tty_termios_encode_baud_rate(). If this rate is close enough to astandard rate however, we could end up setting CIBAUD to a Bfoo valuedespite the user having left it unset.This in turn could lead to an unexpected input rate being set onsubsequent termios updates.Fix this by using a zero tolerance value also for the input rate whenCIBAUD is clear so that the matching logic works as expected.Fixes: 78137e3b34e1 ("[PATCH] tty: improve encode_baud_rate logic")Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/tty/tty_baudrate.c
