260b2a20f2 Provide PMAP_{,UN}MAP_POOLPAGE(). 1998-07-24 22:03:33 +00:00

b916de0f86 Add special memory allocation routines that supports allocation 
DMA-able memory in small chunks (USB uses a lot of 8 byte chunks).
Using the bus_dma functions directly is inefficient.

bf51a1d137 uvm_deallocate() takes an address and a size, not an address range. From

8325d058bf Implement uvm_km_{alloc,free}_poolpage(). These functions use pmap hooks to 
map/unmap pool pages if provided by the pmap layer.

fc4828b0b4 A few small changes to how pool pages are allocated/freed: 
- If either an alloc or release function is provided, make sure both are
  provided, otherwise panic, as this is a fatal error.
- If using the default allocator, default the pool pagesz to PAGE_SIZE,
  since that is the granularity of the default allocator's mechanism.
- In the default allocator, use new functions:
	uvm_km_alloc_poolpage()/uvm_km_free_poolpage(), or
	kmem_alloc_poolpage()/kmem_free_poolpage()
  rather than doing it here.  These functions may use pmap hooks to
  provide alternate methods of mapping pool pages.

7d8833a179 Put back swap_data_lock, which was apparently deleted accidentally during 
the last round of changes.  (I noticed it because I run my kernels w/
LOCKDEBUG.)

3d545acb51 Overload the generic "copyrows" function by a private one which implents 
a "fast scroll" by setting the display start in memory.
(Only implemented for "scroll up" because this is more used. "scroll down"
is easy to add.)
This moves the semantics of "copyrows" to something like "moverows";
the contents of the new visible lines at the bottom is undefined.
The emulations can live without the original "copy" semantics.

1c2f0a15fd Don't create the extent region pool until one of our callers is of the 
opinion that it's safe to call malloc.

8ba3494f9a Deal with new pool code's changed API by rewriting this to not use pools. 
Instead, use a manually maintained freelist in a second tailq.
Uses less data space, looks more symmetrical.

458ba64f3a Slight variation on last; be a bit more zealous about fixing up the 
clock source.  Now, when my EtherPower II locks up, it eventually recovers!

(Geez, I'd like to know why it does this, and only apparently in 10mb/s mode).
