| | | | | | | | | | | | | significantly reduces booting time when there is broken floppy disk drive, controller, cable, BIOS, etc. When the floppy controller interface is correctly implemented, disk change signal (DSKCHG) is reflected in the Digital Input Register (DIR) at 0x3f7.

National Semiconductor PC8477B datasheet says the same. As a side effect, we no longer use Configuration Control Register (CCR) at 0x3f7 for these controllers, which is often missing in modern hardware. Notes: svn path=/head/; revision=160137

Instead, use callout_stop(). Note that since we hold the associated mutex and are now using callout_init_mtx(), callout_stop() is just as effective as callout_drain(). (Though callout_drain() is still needed in detach to make sure softclock isn't contesting on our mutex before we destroy the mutex.) - Remove unused callout 'tohandle' from softc.

* If we fail a sanity check for the resources just allocated, make sureWarner Losh2005-03-151-1/+3
| | | | | | | | | | that we free that resource. All the other resources are freed in their own routine, but since we haven't saved a pointer to this one, it is leaked. This is the failure case that lead to the sio ports that weren't working, I think. Notes: svn path=/head/; revision=143618

* Fix a couple of problems with the probe code when used with pnpbiosWarner Losh2005-03-101-9/+23
| | | | | | | | | | | | | | | | | | | | | resources. When allocating 6 ports for a 4 port range isa code returns an error. I'm not sure yet why this is the case, but suspect it is just a non-regularity in how the resource allocation code works which should be corrected. Use 1 as the ports size in this case. However, in the hints case, we have to specify the length, so use 6 in that case. I believe that this is also acpi friendly. Also, complain when we can't allocate FDOUT register space. Right now we silently fail when we can't. This failure is referred to above. When there's no resource for FDCTL, go ahead and allocate one by hand. Many PNPBIOS tables don't list this resource, and our hints mechanism also doesn't cover that range. If we can't allocate it, whine, but fake up something. Before, we were always bogusly faking it and no one noticed the sham (save the original author who has now fixed his private shame). Notes: svn path=/head/; revision=143380

| | | | | | | | | | | | | | | | | | | | Rather than have a twisty maze of special case allocations, move instead to a data driven allocation. This should be the most robust way to cope with the resource problems that the multiplicity of ways of encoding 5 registers that have the misfortune of not being a power of 2 nor contiguous. Also, make it less impossible that pccard will work. I've not been able to get my libretto floppy working, but it now fails later than before. phk and I had similar ideas on this during the 5.3 release cycle, but it wasn't until recently that I could test more than one allocation scenario.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | and 0x3f7. fdc_isa_alloc_resource() didn't work right in this case (it accessed FDOUT correctly due to an overflow of the first resource. It accesed FDSTS and FDDATA incorrectly via the second resource (which wound up accessing FDOUT and the tape register at 0x3f3) and badly for the CTL register (at location 0x3f4). This is a minimal fix that just 'eats' the first one if it covers two locations and has an offset of 0. This confusion lead the floppy driver to think there'd been a disk change, which uncovered a deadlock in the floppy/geom code which lead to a panic. These changes fix that by fixing the underlying resource problem, but doesn't address the potential deadlock issue that might still be there. This is a minimal fix so it can more safely be merged into 5 w/o risk for known working configurations (hence the use of the ugly goto, which reduces case 8 to case 6 w/o affecting cases 1-7). A more invasive fix that will handle more ACPI resource list diversity is in the pipeline that should kill these issues once and for all, while staying within the resources that we allocate.
