* For the moment, treat failures to attach floppy drives as non-fatalWarner Losh2004-09-161-2/+0
| | | | | | | | | | errors for the attachment process for the floppy controller. This is a band-aide because it doesn't try any of the fallback methods when _FDE isn't long enough, but should be sufficient for people experiencing the dreaded mutex not initialized panic.

* Checkpoint the fdc resource changes:Warner Losh2004-09-144-121/+121
| | | | | | | | | | | | | | | o Allow for up to 3 resource I/O ranges to be given for the floppy controller, rather than just two that are allowed for now. o Make sure that we can work with either a base address of 0x3f0 or 0x3f2. o Create new inline functions to access the YE DATA's unique BDCR register. o Update pccard attachment to add the fd device. o Do some minor style(9) polishing. # I'm guessing that the fdc pccard attachment broke some time ago, since # there are a number of issues with it still.

* When ISA_PNP_PROBE is called, it will return 0 when it finds a device,Warner Losh2004-08-311-2/+1
| | | | | | | | | | | | | | | | ENOENT when there's no PNP ID for this device node, or ENXIO when there is one, but it doesn't match. In the nonPNP case (as most Alpha systems appear to be), we were treating the error return as an error, when it should be have ignored it. Version 1.9 properly ignored it, but the attach re-write of 1.10 introduced this logic error.

| | | | | | | | | | | | the old one is. Hence we need to evaluate the old one for _FDI since it has a valid ACPI_HANDLE ivar. This is a minimal fix. Make a note that a more complete one is to make fdc support the ACPI_HANDLE ivar for its children. This and the previous change are MT5 candidates. Notes: svn path=/head/; revision=134534

(We handle the case of adjusting for a start of 0x3f2 -> 0x3f0 separately, although that code should still be checked if there are still floppy problems for others.)

* Rewrite of the floppy driver to make it MPsafe & GEOM friendly:Poul-Henning Kamp2004-08-205-1881/+1355
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Centralize the fdctl_wr() function by adding the offset in the resource to the softc structure. Bugfix: Read the drive-change signal from the correct place: same place as the ctl register. Remove the cdevsw{} related code and implement a GEOM class. Ditch the state-engine and park a thread on each controller to service the queue. Make the interrupt FAST & MPSAFE since it is just a simple wakeup(9) call. Rely on a per controller mutex to protect the bioqueues. Grab GEOMs topology lock when we have to and Giant when ISADMA needs it. Since all access to the hardware is isolated in the per controller thread, the rest of the driver is lock & Giant free. Create a per-drive queue where requests are parked while the motor spins up. When the motor is running the requests are purged to the per controller queue. This allows requests to other drives to be serviced during spin-up. Only setup the motor-off timeout when we finish the last request on the queue and cancel it when a new request arrives. This fixes the bug in the old code where the motor turned off while we were still retrying a request. Make the "drive-change" work reliably. Probe the drive on first opens. Probe with a recal and a seek to cyl=1 to reset the drive change line and check again to see if we have a media. When we see the media disappear we destroy the geom provider, create a new one, and flag that autodetection should happen next time we see a media (unless a specific format is configured). Add sysctl tunables for a lot of drive related parameters. If you spend a lot of time waiting for floppies you can grab the i82078 pdf from Intels web-page and try tuning these. Add sysctl debug.fdc.debugflags which will enable various kinds of debugging printfs. Add central definitions of our well known floppy formats. Simplify datastructures for autoselection of format and call the code at the right times. Bugfix: Remove at least one piece of code which would have made 2.88M floppies not work. Use implied seeks on enhanced controllers. Use multisector transfers on all controllers. Increase ISADMA bounce buffers accordingly. Fall back to single sector when retrying. Reset retry count on every successful transaction. Sort functions in a more sensible order and generally tidy up a fair bit here and there. Assorted related fixes and adjustments in userland utilities. WORKAROUNDS: Do allow r/w opens of r/o media but refuse actual write operations. This is necessary until the p4::phk_bufwork branch gets integrated (This problem relates to remounting not reopening devices, see sys/*/*/${fs}_vfsops.c for details). Keep PC98's private copy of the old floppy driver compiling and presumably working (see below). TODO (planned) Move probing of drives until after interrupts/timeouts work (like for ATA/SCSI drives). TODO (unplanned) This driver should be made to work on PC98 as well. Test on YE-DATA PCMCIA floppy drive. Fix 2.88M media. This is a MT5 candidate (depends on the bioq_takefirst() addition).

* Fix ACPI floppy enumeration for three types of divergent behavior.Nate Lawson2004-07-281-40/+90
| | | | | | | | | | | | | | | | | | | | * Some systems have _FDE and child floppy devices, but no _FDI. This seems to be compatible with the standard. Don't error out if there is no _FDI. Instead, continue on to the next device. The normal fd probe will take care of this device. * Some systems have _FDE but no child devices in AML. For these, add a second pass that compares the results of _FDE to the presence of devices. If not present, add the missing device. * Some BIOS authors didn't read the spec. They use tape drive values for all fdc(4) devices. Since this isn't grossly incompatible with the required boolean value, use them. They also define the _FDE items as a package instead of buffer. Regenerate the buffer from the package if it is present. Tested by: tjr, marcel Notes: svn path=/head/; revision=132810

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
