- Determine and remember if we are a floppy.
- Workaround for what is apparently a firmware bug - ignore the sector
size returned by the device. On my Firepower's floppy, block-size
is the same as max-transfer, which causes Lossage.
- Don't read the disklabel on a floppy; do what the ISA floppy driver
does, which is assign the entire disk to each "partition", although
we do not deal with the density stuff.
- FIREPOWERBUGS -> FIRMWORKSBUGS
- Some general cleanup.
by default if it's usable, but falling back to I/O space if mem isn't usable.
If NCR_IOMAPPED is defined (default on the x86), prefer I/O space
then fall back to mem. Also, clean up the various memory consistency checks
so that they can deal with run-time determination of whether or not the
device is to be memory- or I/O-mapped.
by default if it's usable, but falling back to I/O space if mem isn't usable.
If TULIP_IOMAPPED is defined (default on the x86), prefer I/O space
then fall back to mem.
mapping register, maps it, and returns all of the relevant information.
deprecate use of pci_{io,mem}_find(), but leave them around (for a while)
for backward compatibility with third-party drivers.
arguments, so that a device can tell if its memory and I/O spaces are
enabled. The flags are cleared, depending on the contents of devices CSR
registers, in the machine-independent PCI bus code.
this code makes equal sense for memory and I/O space, prefer to map
the PCI front end via memory space (conditionalized on a patchable kernel
variable), and do a bit of other random NetBSD-specific cleanup. (These
changes were sent to Justin Gibbs on March 28.)
This can be disabled (to save a bit of space) with the NO_KERNEL_RCSIDS
options, which is present but commented out in the ALPHA config file.
In ELF-format kernels, these strings are present in the kernel binary but
are not loaded into memory. (In ECOFF-format kernels, there's no easy way
to keep them from being loaded, so they _are_ loaded into memory.)
* Don't print DMA_OUT message in the `normal' case of a 16-byte residual.
* ioasic-connected 53c94 devices are always clocked at 25MHz even on
machines with 12.5MHz TurboChannel.
