9dc368e353 Clean up read_region_2 code to use fast version under more circumstances, and 
to always use it aligned on a 4-word boundary.  The setup code feels like
it could be sleeker, but I can't currently see how.

6a2268f94f Faster bus_space_read_region_2(), using LDM and STM to process 16 bytes at a 
time where possible.  This almost doubles the speed of reading through the
sec(4) in my A540.

5375dc7f10 New driver, sec(4), for the Acorn SCSI Expansion Card. Unlike asc(4), this 
driver uses the board's DMA system, uses the machine-independent WD33C93
driver, works on NetBSD/acorn26, and doesn't share a name with six other
machine-dependent SCSI drivers.  Not tested on acorn32, but it seems to
work tolerably well on my A540.

e9030bd381 Move over to using the standard ARM bus_space implementation on acorn26. 
This is more flexible than the old acorn26 bus_space, which means that single
read/write operations are slower, but multi and region operations have the
potential to be faster, and particularly insane podules might be supportable.
In theory the acorn32 mainbus and podulebus code ought to be shareable, but
acorn26 needs the extra overhead of saving R14_svc on some operations so
I've made my own version for now.  Also the acorn32 bus_spaces are a mess.

213f273e6a Calls to bus_space_barrier() on acorn26 were very few and using constants that 
were two generations obsolete.  Since they do nothing anyway, remove them
rather than trying to update them.

557f409231 No need to do silly asm() dances to get R14_svc saved now -- the compiler 
does it for us everywhere.

8e80f0df78 Don't specify -fomit-frame-pointer -mno-apcs-frame, since that breaks kernel 
page faults.
 2006-09-28 23:23:22 +00:00
bjh21
87e6985bed Add -mapcs-frame -fno-omit-frame-pointer to acorn26 kernel builds. This 
is necessary to ensure that GCC saves R14_svc on entry to every function,
and thus that page faults within the kernel are safe (since they corrupt
R14_svc).  I think this used to be the default, but it's not any more.

826ff5f060 Make db_validate_address() work, even when called from within an interrupt 
handler.  This should make debugging prefetch aborts slightly simpler.

5858e7aa70 Arrange that catching an unexpected data abort in the kernel causes a trap 
into DDB where possible, even if it happens in an interrupt handler.

83d7ac871e Turn address exceptions into SIGSEGV rather than SIGBUS, since they're really 
just attempts to access unmapped (and incidentally unmappable) memory,
rather than anything special.

7841bf68c0 uvm_fault has been sensible about when to return ENOMEM for some time now, 
so it's reasonable for us to kill processes when we get it returned,
rather than sleeping.  Do that.

7a51d4dddc Add an extra cookie to the ioctl and mmap wsdisplay accessops that points 
to the screen on which they are being called.  The driver cannot guess
this by itself but it is needed to implement, at least, the getwschar and
putwschar functions in the correct place.  There are no functional changes
yet.

Tested on i386 (vga, vga_raster, machfb, vesafb), macppc and sparc64.

dc1372c547 Add stf to all kernel configs which have INET6 and gif, except the INSTALL

OK'ed by rpaulo.

N.B. stf is a cloning device, so it still must be enabled by
"ifconfig stf0 create".
