* Remove new options and my prevention of system freeze when the sio probeDoug Ambrisko2004-05-031-76/+49

* Some enhancements and bug fix.Doug Ambrisko2004-04-301-49/+76
| | | | | | | | | | | | | | | | | | | | | - Define option FORCECONSPEED to force the serial console to be CONSPEED. I've run into a lot of boards in which the detect for prior speed doesn't work and ends up with broken console since it is at the wrong speed. - If a serial port is marked as a console, but console=vidconsole and if the serial ports doesn't exist it will be probed and attached at a 8250 chip. Then writes to that will freeze the system. - Add an option flags 0x400000 to mark this as a potential comconsole in-case the one flaged with 0x10 does not exist in the system. This makes it easier to deploy on systems with one or two serial ports. Obtained from: IronPort Notes: svn path=/head/; revision=128781

* Device megapatch 4/6:Poul-Henning Kamp2004-02-211-1/+2
| | | | | | | | | | | Introduce d_version field in struct cdevsw, this must always be initialized to D_VERSION. Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing four D_NOGIANT flags and adding 145 D_NEEDGIANT flags. Notes: svn path=/head/; revision=126080

Complete asserts that dev_t's passed to ttyread(), ttywrite(), ttypoll() and ttykqwrite() have (d_flags & D_TTY) and a struct tty pointer. Make ttyread(), ttywrite(), ttypoll() and ttykqwrite() the default cdevsw methods for D_TTY drivers and remove the explicit initializations in various drivers cdevsw structures.

* Fixed breakage of a check for boolean true by misusing NULL in rev.1.407.Bruce Evans2003-12-241-2/+2
| | | | | | | This became fatal when the type of NULL was changed recently. Notes: svn path=/head/; revision=123796
* Tweaked the siointr1() so that it works better at 921600 bps, especiallyBruce Evans2003-11-171-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | with multiple ports on a shared interrupt demultiplexed by the puc_intr() handler. siointr1() first read as much input as possible and then checked all possibly-relevant status registers, partly for robustness and partly for historical reasons. This is very bad if it is called for every port sharing an interrupt like puc_intr() does. It can spend too long reading all the input for some ports when the interrupt is for a more urgent event on another, or just too long checking all the status registers when there are lots of ports. The inter-character time is too long for reading all the input even when the interrupt is for a transmitter interrupt on the same port, and at 921600 bps the inter-char time is 10.85 usec and was often exceeded with just 2 ports, leaving the transmitters idle for about 6% of the time. The tweak is to break out of the read loop after reading 1 char if output can be done. This avoids most of the idle transmitter time for 2 active ports at 921600 bps bidirectional on the test system. It also reduces overhead by about 20%. More complete fixes use the programmable tx low watermark on 16950's and reduce overhead by another 65%. Notes: svn path=/head/; revision=122844
* Don't waste so much space for the latency debugging buffer. Its sizeBruce Evans2003-11-161-10/+8
| | | | | | | | | | | | | | | will now need editing except for spot checks. Changed this buffer from a circular one to a linear one. This is more useful for some cases and the sysctl that prints it doesn't support circular buffers. Fixed (output) formatting bugs in this sysctl. An off by 1 error caused a garbage byte to be returned after annotation of large deltas, and a race with the writer sometimes caused premature string termination. Notes: svn path=/head/; revision=122819
* Removed some nearly dead code in comparam(). We don't need to recoverBruce Evans2003-09-281-9/+0
| | | | | | | | | from fiddling with CS_TTGO since fiddling with CS_TTGO was removed in rev.1.218 of the i386/isa version (which was merged with loss of history in rev.1.223 of this version). Notes: svn path=/head/; revision=120553
* Cleaned up and fixed setting of speeds in comparam():Bruce Evans2003-09-271-31/+20
| | | | | | | | | | | | | | | | | | | | - Removed conversion of a zero input speed to the output speed. This has been done better in ttioctl() since rev.1.108 of kern/tty.c almost 5 years ago. comparam() did the conversion incompletely for the case where the output speed is also zero. It had complications to avoid using zero speeds, but would still have used a zero input speed for setting watermarks if kern/tty.c had passed one. - Never permit the input speed to be different from the output speed. There was no validity check on the input speed for the case of a zero output speed. Then we didn't change the physical speeds, but we used the unvalidated input speed for setting watermarks and didn't return an error, so ttioctl() stored the unvalidated input speed in the tty struct where it could cause problems later. - Removed complications that were to avoid using a divisor of 0. The divisor is now always valid if the speed is accepted. Notes: svn path=/head/; revision=120505

| | | | | | | | | | in the loopback test in the probe. The delay was too short for consoles at speeds lower than about 3200 bps. This shouldn't have caused many problems, since such low speeds are rare and the probe is forced to succeed for consoles. Notes: svn path=/head/; revision=120468

| | | | | | | | | | | | | | | COM_NOFIFO() and COM_ESP cases are supposed to be a subsets of the plain 16550A case, but 16650-related changes made the former fall into the latter and then both fall into general code for printing the tx fifo size. This mainly caused hard to parse boot messages like: "sio0: type 16550A fifo disabled lookalike with 1 bytes FIFO". COM_NOFIFO() on an ESP port gave a larger mess whose extent is not clear. Fixed some nearby style bugs. Notes: svn path=/head/; revision=120173
* Cleaned up initialization of hardware flow control for 16650As. UseBruce Evans2003-09-171-25/+11
| | | | | | | | | | | | | | | | | defined values instead of hard-coded values. Don't repeat the register access part of the code 4 times times or triple-space statements. This fixes half of the style bugs in rev.1.172. Hardware flow control of 16650As is still officially unsupported. I was mistaken about it being broken. It is broken in 16650s but is fixed in 16650As except for the maximum trigger level (which is no longer used). Testing of the 16650's broken hardware flow control watermarks by programming them on 16950s showed that their effects are not too bad if the fifo size and trigger level are reasonably large (16 is much better than 8).

* Quick fix for a pessimization in rev.1.194. An extra i/o instructionBruce Evans2003-09-151-2/+7
| | | | | | | | | | | | was added to the fast path to support the COM_IIR_RXRDYBUG() case even when that case is not configured. This increased the relative overhead of sio input by almost 25% in the worst case and by 2-3% in the usual case (usually only about 0.2% absolute per port at 115200 bps). The quick fix is to significantly pessimize only the COM_IIR_RXRDYBUG() case. Notes: svn path=/head/; revision=120091

* - Use the new resource_disabled() helper function to see if devices areJohn Baldwin2003-07-021-5/+3
| | | | | | | | | | | | | | | disabled. - Change the apm driver to match the acpi driver's behavior by checking to see if the device is disabled in the identify routine instead of in the probe routine. This way if the device is disabled it is never created. Note that a few places (ips(4), Alpha SMP) used "disable" instead of "disabled" for their hint names, and these hints must be changed to "disabled". If this is a big problem, resource_disabled() can always be changed to honor both names. Notes: svn path=/head/; revision=117167
