mrg ca5133d3fb remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h> 2000-06-29 08:22:17 +00:00
simonb 889c658b5b Change the kernel mmap interface so that the offset to map is an 
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes.  Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".

Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.

cgd cffb580806 Implement the more flexiable `evcnt' interface as discussed (briefly) on 
tech-kern and now documented in evcnt(9).

thorpej b3b7588160 Don't use sleep() and callouts; just use tsleep(). 2000-05-27 04:42:14 +00:00
thorpej 6dd5a9db6e Use dev/isa/fd.c. 2000-04-07 16:35:19 +00:00
thorpej b667a5a357 New callout mechanism with two major improvements over the old 
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

thorpej a183d34f04 - Implement cnbell() -- ring the console bell. The cn_bell entrypoint 
is optional.
- Add cn_bell to statically allocated consdevs as appropriate.

thorpej 52a2804a5c Add a new function call to the ISA DMA API: isa_dmamaxsize(), which returns 
the maximum transfer size for the specified DMA channel.  Make all clients
of ISA DMA use this call to determine their maximum transfer size.

thorpej fe551f0e64 Fix a bug in disksort_*() which caused non-optimal ordering when multiple 
active partitions were on a single spindle.  Add a b_rawblkno member to
struct buf which contains the non-partition-relative block number to sort
by.

mrg db3051d720 fix problems in many d_mmap routines: 
- returned EOPNOTSUPP rather than -1.
	- no check for negative offset.
many of these fix potential security problems in these drivers.


XXX XXX XXX
the d_mmap cdev routine should be changed to have a prototype like:
	paddr_t (*d_mmap) __P((dev_t, off_t, int));

by someone!

thorpej 49a45fed9b If the memory range of the machine is such that no bouncing is necessary, 
or if the device is capable of 32-bit DMA (specified by ISABUS_DMA_32BIT),
clear the map's bounce threshold at map creation time.

thorpej 680a3d77f4 Add isa_dma{freeze,thaw}(), used to temporarily stop and then restart 
all ISA DMA.  Needed by e.g. the SmartCard reader for Sharks.
 1998-06-09 01:04:17 +00:00
thorpej 0b76aff07b Change the ISA DMA API to take an isa_chipset_tag_t rather than 
a struct device * corresponding to the ISA bus device.  The ISA DMA
controller driver functions have been renamed and now take a struct
isa_dma_state *, and are called indirectly by machine-dependent code
which provides the DMA state.

These changes allow e.g. `ofisa' (the OpenFirmware configuration
mechanism for the ISA bus, used by e.g. Sharks) to use the MI ISA
DMA controller code.

thorpej f8acb6d6fa Sync w/ i386 port:

thorpej 52450409d6 Sync w/ i386 port: 
Implement bounce buffers for mbufs.

Also, correct copyright snafus, and a forgot-o left over from a commit
I made yesterday.
 1998-06-03 21:52:36 +00:00
thorpej 7b37a276e2 Sync w/ i386 port: 
Optimize the ISA DMA map load somewhat; don't traverse the buffer twice.
Instead, just attempt to do a normal load first.  If we exceed the bounce
threshold or the number of segments, then we bounce the transfer.
