971dd06182 Adapt ISA console selection ti new mi drivers. 
(was broken anyway, a "++" was missing somewhere)

164f56220e Add support for the Cypress CY82C693 PCI-ISA bridge. This bridge is more or 
less like an Intel SIO except that the ELCR registers are accessed differently
than on the Intel SIO.

XXX This code needs to be split up into bridge front-end and PIC back-end
XXX pieces.

4c01c3c48e Pass the pci_chipset_tag_t to sio_intr_setup(). XXX This code should be 
rearranged so that other non-PCI-but-in-all-other-ways-ISA-PIC-like
devices can share code.

b21bfbde11 Add -Wno-main conditional on compiler being gcc 2.8 or egcs. (This adds 
a HAVE_GCC28 check-variable that can now be used to add other gcc-2.8
flags in cases where they may be useful, or to remove gcc 2.7.2 "bug
workaround" flags.)

e40e2ff2d0 A little buglet: softc for pceb is same as sio- so declare it as such. 
By not doing so, a very obscure bug followed where the config search
stuff stopped at the bridge (pceb) and didn't even call match for the
two Qlogic ISP cards that followed.

ce4810822b Add autoconfiguration support for the Cypress 82C693 PCI-ISA bridge,

a95651eaea Add a PMAP_KERNEL_PTE() macro that returns the PTE for a given KVA. If 
DEBUG, this performs a table walk.  Othwise, the Virtual Page Table is
used.  Use this macro in a few places where this was done by-hand.

Make vtophys() use PMAP_KERNEL_PTE().  In non-DEBUG cases, this is
a fair bit faster.

b1e15c2005 Add some robustness to pmap_alloc_physpage(): Instead of panic'ing if 
we can't get a page, find an inactive pmap and pmap_collect() it,
freeing up a few pages.  Go ahead and die if we can't allocate a page
after 5 tries.
 1998-03-27 00:52:43 +00:00
thorpej
b86884a71a Give pmap_collect() some substance: when called, a process is being 
swapped out, so remove all of the physical mappings the process has
in order to free up the page table pages.

Since the pmap module is allowed to "forget" mappings, pmap_collect()
may be called in other situations where the memory situation is desperate,
although it's more likely that the pages will simply be needed again the
next time a process runs.

531db9e0d3 Sanity check the virtual addresses in the kernel and non-kernel cases 
of pmap_enter() (and pmap_kenter_*()).  Remove diagnostic check for
kernel pmap in pmap_alloc_asn().

040f7cbc70 Remove references to pmap.old.h - It should have just been pmap.h, but 
that isn't necessary, either, since <vm/vm.h> is already included.

3ac5a77c70 Make pmap_kremove() deal with mappings entered with pmap_enter() as well. 
Prevents stale PV entries from lingering around.  Fixes a nagging
"kernel stack not valid halt" I was seeing with PMAP_NEW.

Idea from Chuck Cranor.

3786a63843 1. Always link at the high address, now that we can use free ram below 
the kernel on most platforms, including all of the entry-level platforms.
2. Kill the comments and options for load address selection.
3. Kill the default -g.

49408401a3 In pmap_destroy_lev1map(), fix a problem where the pmap's ASN wouldn't 
be invalidated if the pmap is not active.  A rare thing (in fact, I'm
having trouble thinking of a scenario where it would happen), but it was
incorrect, nonetheless.
