6a9bccd130 Make absolutely sure page tables are not cacheable on 040/060 cpus. 
(Not strictly required for the 040, but mandatory for the 060).
Also revamp cache enable/disable functions for the benefit of
bus_dmamem_map().

8593b82c71 One less item (h/w assisted soft interrupts) 2001-07-06 20:12:34 +00:00

35110949ce Ditch the `simulated' software interrupt in favour of 
hardware-assisted soft interrupts on all boards.
(Note: VMEChip2-less 162/172 not yet tested)

This greatly simplifies the `rei' path and allows
interrupt nesting to be tracked somewhat more easily.

As a result we now have a working CLKF_INTR() macro
and can detect uvm_fault() being called from an interrupt
(although there may still be a very short race detecting
the latter; need to investigate further).

8aad61265b On 162 and up, get the CPU speed from the firmware and only fall back 
to calculating it on the fly if the firmware's value is bogus.

This fixes problems caused by rounding errors on some board/speed
combinations.

aab2376d45 Refuse to boot on 162/172 and 167/177 if the user has not removed 
the jumper which tells 1xx-Bug where to locate its scratch data.

Instead, print a message informing the user to RTFM (which needs to
be updated to include this info. ;-)

c22fb1db55 Finally nobble the bus_dmamap_sync() problem with osiop(4). 
Basically, bus_dmamap_sync() `PREREAD' needs to flush the cache
for the start and end of the region if it is not aligned to
a cacheline boundary, otherwise a subsequent POSTREAD can *purge*
valid data which was in the cacheline but *outside* the region
passed to bus_dmamap_sync().

Bus snooping doesn't always help here because osiop(4) calls
bus_dmamap_sync() with POSTREAD even if no data was actually
transferred! (And we can't rely on snooping on the 68060 models anyway).

2b27ac7a99 Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for 
each vm_page structure.  Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM.  These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.

This deprecates struct pmap_physseg.  As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.

Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now).  Changes to other pmap
modules will follow.
