Rather than keying on the size of the resource being 2, instead key off the end & 7 being 3. This covers the same cases that the size of 2 would catch, but also covers the new above case. In addition, I think it is clearer to use the end in preference to the size and start for case #8 as well. Turns two tests into one, and catches no other cases. Make minor commentary changes to deal with new case #9. # This change is specifically minimal to allow easy MFC. A more # extensive change will go into current once I've had a chance to test # it on a lot of hardware... Approved by: re@ (kensmith) Forgotten by: imp@ Notes: svn path=/stable/5/; revision=137023

* 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

* Disable the use of cloning use in floppy and CD drivers.Poul-Henning Kamp2003-09-111-6/+6
| | | | | | | | | | | | | This commit puts the relevant code snippets under #ifdef GONE_IN_5 (rather than #ifndef BURN_BRIDGES) thereby disabling the code now.

| | | | | | | | | | | | | | For the floppy driver, use fdcontrol to manipulate density selection. For the CD drivers, the 'a' and 'c' suffix is without actual effect and any applications insisting on it can be satisfied with a symlink: ln -s /dev/cd0 /dev/cd0a Ongoing discussion may result in these pieces of code being removed before the 5-stable branch as opposed to after.

* - Use the new resource_disabled() helper function to see if devices areJohn Baldwin2003-07-021-3/+2
| | | | | | | | | | | | | | | 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
