2006-06-28[PATCH] remove TTY_DONT_FLIPPaul Fulghum
Remove TTY_DONT_FLIP tty flag. This flag was introduced in 2.1.X kernels to prevent the N_TTY line discipline functions read_chan() and n_tty_receive_buf() from running at the same time. 2.2.15 introduced tty->read_lock to protect access to the N_TTY read buffer, which is the only state requiring protection between these two functions. The current TTY_DONT_FLIP implementation is broken for SMP, and is not universally honored by drivers that send data directly to the line discipline receive_buf function. Because TTY_DONT_FLIP is not necessary, is broken in implementation, and is not universally honored, it is removed.

2006-03-31[PATCH] Decrease number of pointer derefs in jsm_tty.cJesper Juhl
Decrease the number of pointer derefs in drivers/serial/jsm/jsm_tty.c Benefits of the patch: - Fewer pointer dereferences should make the code slightly faster. - Size of generated code is smaller - Improved readability Signed-off-by: Jesper Juhl <jesper.juhl@gmail.com> Acked-by: "V.

2006-02-01[PATCH] jsm: fix for high baud rates problemV. Ananda Krishnan
Scott Kilau <Scott_Kilau@digi.com> Digi serial port console doesn't work when baud rates are set higher than 38400. So the lookup table and code in jsm_neo.c has been modified and tested. Please let me have the feed-back.

2005-08-31[SERIAL] Clean up and fix tty transmission start/stopingRussell King
The start_tx and stop_tx methods were passed a flag to indicate whether the start/stop was from the tty start/stop callbacks, and some drivers used this flag to decide whether to ask the UART to immediately stop transmission (where the UART supports such a feature.) There are other cases when we wish this to occur - when CTS is lowered, or if we change from soft to hard flow control and CTS is inactive. In these cases, this flag was false, and we would allow the transmitter to drain before stopping. There is really only one case where we want to let the transmitter drain before disabling, and that's when we run out of characters to send. Hence, re-jig the start_tx and stop_tx methods to eliminate this flag, and introduce new functions for the special "disable and allow transmitter to drain" case.

2005-07-27[PATCH] jsm: warning fixesV. ANANDA KRISHNAN
- updates the version - fix mixing of declarations and code. The mixing of declarations and code displays warnings when used against RedHat RHEL4.0 distro (compiler version is 3.4.3-22.1) and hence I separated them out.

2005-07-27[PATCH] jsm: use dynamic major number allocationV. ANANDA KRISHNAN
The jsm driver uses a static number of 253. The major number 253 is a reserved for "LOCAL/EXPERIMENTAL USE" by both char and block devices. So take advantage of the dynamic allocation of major number by the kernel. Signed-off-by: V.

2005-04-16[PATCH] fix up newly added jsm driverChristoph Hellwig
- plug various leaks and use after frees in the remove and initialization failure path (some still left) - remove useless global list of boards and use pci_set_drvdata instead - unobsfucate init path by merging functions together - kill various totally useless state variables - .. probably more I forgot Note that the tty part still generates lots of sparse warnings and there's still a totally useless layer of function pointer indirections, but maybe someone else will fix that bit up.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
