revert "x86, serial: convert legacy COM ports to platform devices"

2007-08-22T23:23:25+00:00

Revert 7e92b4fc345f5b6f57585fbe5ffdb0f24d7c9b26. It broke Sébastien Dugué's machine and Jeff said (persuasively) This seems like it will break decades-long-working stuff, in favor of breaking new ground in our favorite area, "trusting the BIOS." It's just not worth it for serial ports, IMO. Serial ports are something that just shouldn't break at this late stage in the game. My new Intel platform boxes don't even have serial ports, so I question the value of messing with serial port probing even more... because... just wait a year, and your box won't have a serial port either! :) I certainly don't object to the use of platform devices (or isa_driver), but the probe change seems questionable. That's sorta analagous to rewriting the floppy driver probe routine. Sure you could do it... but why risk all that damage and go through debugging all over again? It seems clear from this report that we cannot, should not, trust BIOS for something (a) so simple and (b) that has been working for over a decade. Much discussion ensued and we've decided to have another go at all of this.

x86, serial: convert legacy COM ports to platform devices

2007-05-08T18:15:23+00:00

Make x86 COM ports into platform devices and don't probe for them if we have PNP. This prevents double discovery, where a device was found both by the legacy probe and by 8250_pnp, e.g., serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A 00:02: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A This also means IRDA devices without a UART PNP ID will no longer be claimed by the serial driver, which might require changes in IRDA drivers and administration. In addition to this patch, you may need to configure a setserial init script, e.g., /etc/init.d/setserial, so it doesn't poke legacy UART stuff back in. On Debian, "dpkg-reconfigure setserial" with the "kernel" option does this. To force the old legacy probe behavior even when we have PNPBIOS or ACPI, load the new legacy_serial module (or build 8250 static) with the "legacy_serial.force" option.

[POWERPC] Open Firmware serial port driver

2007-02-14T00:50:04+00:00

This can be used for serial ports that are connected to an OF platform bus but are not autodetected by the lecacy serial support. It will automatically take over devices that come from the legacy serial detection, which usually is only one device. In some cases, rtas may be set up to use the serial port in the firmware, which allows easier debugging before probing the serial ports. In this case, the "used-by-rtas" property must be set by the firmware. This patch also adds code to the legacy serial driver to check for this.
