90dfa8d8ff Undo my accidental revival of pmap_kenter_pgs(). 2001-04-25 16:30:03 +00:00

7cf0a5e592 Arrange the "unamanaged" pages (entered through pmap_kenter_pa()) are tracked 
and ignored as necessary.

05d087e7c7 Remove definitions of CLKF_*. They're defined in <arm/cpu.h> now. 2001-04-24 18:15:44 +00:00

1c3a62e066 Sprinkle pmap_update() calls after calls to: 
- pmap_enter()
- pmap_remove()
- pmap_protect()
- pmap_kenter_pa()
- pmap_kremove()
as described in pmap(9).

These calls are relatively conservative.  It may be possible to
optimize these a little more.

55044638aa Remove pmap_kenter_pgs(). It was never really adopted by 
anything, and the interface itself wasn't as flexible as
callers would have probably liked.

ec66f67f3a Use pmap_kenter_pa() rather than pmap_kenter_pgs(). 2001-04-22 23:28:52 +00:00

69abdbf60c Undo a misguided previous change to the pmap_update() API. 2001-04-22 23:19:26 +00:00
thorpej
5871b80f00 Use uvm_pageboot_alloc() for early memory allocation, rather than 
calling pmap_steal_memory() directly.  On these platforms, since
uvm_pageboot_alloc() is a wrapper around pmap_steal_memory(), there
is no functional change.  This is merely for API consistency.

cfb5c7ed9f Make pmap_virtual_space() a required pmap function, even on platforms 
which have pmap_steal_memory().  This is to reduce the API differences
between pmaps that implement pmap_steal_memory() and pmaps which do
not.

Note that pmap_steal_memory() needs to adjust *vstartp and/or
*vendp only if it used addresses within the range provided to UVM
via the pmap_virtual_space() call.  I.e. it is not necessary to do
so in any current pmap_steal_memory() implementation.

856547f067 Driver for Archimedes parallel ports. I haven't got a parallel printer, so 
this is currently untested.

4738622712 Give pmap_update() an argument (a pmap_t) so that it knows which 
pmap it should be updating.

660a20cd22 Add a skeleton driver for the random latches on the Archimedes, which are 
shared between the printer port and floppy drive.  Useful facilities will be
added when I know what I need.

us accounting for interrupt time.

sparc port.

5a15be6a18 Don't panic on a stray IRQ, just log it and hope it goes away. This works for 
my acemidi card at least.

bf2dcec4f5 Remove the use of splimp() from the NetBSD kernel. splnet() 
and only splnet() is allowed for the protection of data structures
used by network devices.

d3c7885319 Make sure that every time we touch the referenced/modified bits, we do a 
pmap_update_page() to get all the mappings of that page up-to-date.

8bd452c648 Create an MI Ether3 driver. It's derived from the arm26 driver, which uses 
my MI SEEQ 8005 driver, which is based on the arm32 ea driver.

2714607c72 Add podulebus_shift_tag, which generates a bus_space_tag_t with a specified 
address shift (stride).  This is necessary because many podules have standard
chips with odd address-bus wiring to allow for using LDM for
bus_space_*_multi_*().

86d6442c28 Move machine-dependent podulebus headers to <machine/podulebus_machdep.h>. 
<dev/podulebus/podulebus.h> is the canonical file to include, and includes
<machine/podulebus_machdep.h>.
<arch/${MACHINE}/poudulebus/podulebus.h> remains for backward compatibility.

61e80eef9b As Richard Earnshaw pointed out, bus_space_copy_1() and bus_space_copy_2() 
had the wrong names and did the wrong things.  Both are now fixed.

5c98fe3fec Gratuitous change of signature for podulebus_irq_establish(). It now takes 
an opaque podulebus_intr_handle_t, which can be found in podulebus_attach_args.
It's actually the slot number, but don't tell anyone.
