- Additional rearrangement for the sake of running on the DECstation some
...
day.
- Convert to use bus_dma.
- Fix cleaning up unaligned start address.
- Correctly determine if the device supports Fast SCSI, and adjust the
minimum sync period accordingly.
- Compute minimum sync period correctly on the 25MHz devices.
- Use GPI2 to determine if we're a 25MHz or 40MHz device.
- Currectly determine SCSI ID and "fast mode enabled" for the built-in
TCDS on DEC 3000 models, using cached information from the PROM environment.

- Allow tcds and asc children of tcds to be cloned.
1998-05-24 23:45:29 +00:00
d3ead78027
Several changes to the TurboChannel Dual SCSI driver:
...
- Fix the autoconfiguration model; the TCDS children don't attach to
TurboChannel, so don't make it look like they do.
- Make the driver use bus_space (not bus_dma yet; soon)
- Recognize the PMAZ-FS (baseboard fast SCSI on DEC 3000s) and the
PMAZB-AA (TCDS option card) and PMAZC-AA (TCDS fast SCSI option card).
- Rearrange it a bit, so that it can eventually be made into an "MI"
TurboChannel driver (i.e. work on DECstations).

1998-05-20 18:09:16 +00:00
a2f214a443
Add fine-grained locking, using a locking protocol modeled after the i386
...
UVM pmap's locking protocol, written by Chuck Cranor. Not all of the
support for multiple processors is here yet, but the kernel does run
under moderate loads with LOCKDEBUG (all locking operations are no-ops
unless LOCKDEBUG is turned on).
This is by no means complete... there are still some possible snares
to take a look at.

It is no longer necessary for pmap_pinit() and pmap_release() to be

Simple screen attribute handling for wscons.
...
The graphics device driver passes a "default attribute" for normal text
output to the wscons framework. If the emulation module needs more
attributes (for different "renditions") it can allocate them via a
callback.
For now, only the "sun" emulation makes use of it.

Garbage-collect the old confargs stuff that was used in the Early Days.

0624060713
Rework PCI interrupt mapping on the EB164 systype. Rather than computing
...
interrupt routing directly, use the interrupt routing information provided
in the PCI "line" register. The previous scheme did not work properly on
AlphaPC 164SXs. Also, be silent about the fact that 0/8/x does not
have its interrupt mapped; this is to be expected on the 164SX (this is
the Cypress PCI-ISA bridge, which has IDE wired to compat mode on functions
1 and 2; the 164SX does _not_ have PCI IDE on device 11 like other AlphaPCs).

Simplify the direct-mapped DMA case somewhat by adding a window base

add Alpha 4100 support

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.

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.

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.)

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.

We don't have software-only maps, so a NULL pmap_t will never be passed
...
to pmap functions.

Remove a comment that is not applicable in NetBSD - we don't have

software-only maps.

Add autoconfiguration support for the Cypress 82C693 PCI-ISA bridge,
...
found on AlphaPC164SX boards.
Partially from Anders Magnusson <ragge@ludd.luth.se>.

GC alpha's ECOFF_TOOLCHAIN make variable, and related bits. Nobody
...
should be using an ECOFF toolchain on NetBSD/alpha any more.

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.

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.

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.

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().

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.
