- Add sysarch methods for "get bus window count", "get bus window",
and "pci conf read/write".
These are a hack, but they're what's necessary in order to make
XFree86 work in its current state.
Like the 1000A, the AlphaServer 1000 has a daughtercard assembly that
integrates the CPU and core logic, so these can be ev4/apecs or ev5/cia.
New systype, and, sigh, another way of doing interrupts and another
mystery icu.
Kill off some EVCNT_COUNTERS calls, since [A] it has to be rewritten anyway
before it can be useful, and [B] #ifdefs do not belong at every call site,
a common API should be defined and the implementations conditionalized, not
all the calls. Duhh.
the iot, memt, and pc in the call so that pci_1000a_pickintr() (and the
other routines in that module) do not need to be aware of the core logic
type just to pass down memory and I/O space tags or to call the decompose
function.
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 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.)
the chipset space init functions multiple times, since that would clobber
extent allocations made between the two calls. Also, deal with the
fact that the APECS and LCA no longer shared common chipset functions.
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).
- split softc size and match/attach out from cfdriver into
a new struct cfattach.
- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.
Support for AXPpci CPUs,
Support for AlphaStation 600 CPUs,
new boot block structure, which requires an 'installboot'
program and works a lot like the NetBSD/sparc boot blocks.
