Andrey A. Chernov fd59ff8180 CHANGES from Bruce: ... --- This list of changes is in approximately chronological order (oldest first). o Many cosmetic changes - renamed comintr1 -> siointr1, moved things around and fixed whitespace. o Reduced SLIP latency (FRAME_END hack) from 20-30 ms to 16 ms at 115200 bps (you won't notice the average 10 ms improvement on slow lines). ppp seems to use only counted transfers so there's no similar hack available. It's too hard for the driver to know the count. o Temporary #ifdefs for new and old interrupt handling (OLD_INTERRUPT_HANDLING decided by setsofttty() not being externally defined. o Don't test for the IIR_NOPEND bit being set - test for the non-fifo part of the iir equalling it like the docs say to. States with other IIR_NOPEND set in combination with the other iir bits are undefined. The docs may be stupid - the old test would not have broken when the fifo bits were introduced. o Noted more problems with DTR wait. o Rewrote console stuff. Still some initialization and state preservation problems. Same for kgdb stuff. The driver doesn't do anything about the console close bug. It needs to be fixed entirely in i386/cons.c. I like chmr's version where the the console driver revectors the device open and close routines. o Temporary (?) #ifdefs for references to tty buffers. o Noted further things to do in (2 comments about 3 places) for phk's change to not touch RTS unless it is being used for flow control. o Temporary #ifdefs for timestamp handling. It needs fixing. The microtime() call breaks the first rule of writing fast interrupt handlers: NO calls to functions that might do slow and bad things. microtime() enables interrupts. This turns out to be only moderately harmful. Also, I want the timestamp copy outside of the normal interrupt handler. o Don't init com->tp early for the !DONT_MALLOC_TTYS case - both sides are NULL. o Worry about com->tp == NULL in siopoll. I don't see how you survived the (incc <= 0 || !(tp->state & TS_ISOPEN)) test. Perhaps early sttys or comcontrols set up the tp's for _all_ the ports before this code is reached.		1994-04-03 11:41:11 +00:00
