dsl | Patch out the 'struct malloc_type' from the isa_dma alloc routines.
All the i386 kernels now build

dyoung | branches: 1.25.12; 1.25.16;
Let us safely detach the ISA bus and devices attaching to the ISA
bus:
1 Add isadetach() for detaching the ISA bus, and add some helper
routines that release resources held for ISA DMA.
2 In isachilddetached(), forget references to child devices.
While I am here, change ISA_DMA_DRQ_ISFREE(...) == 0 to the simpler
expression, !ISA_DMA_DRQ_ISFREE(...).

A few ISA sound drivers like to share dma channels, and hence deferred
isa_dmamap_create() calls to their open/close entrypoints. This worked
with some luck, but broke on i386 when _bus_dmamap_create started
to allocate bounce buffers upfront, since memory below 16M may well
not be available when the sound devices is opened for the Nth time.
To fix this, create a new simple interface, isa_drq_alloc/isa_drq_free,
wrappers around already existing bitmask macros. These are expected
to be used before an isa_dmamap_create call, and after an
isa_dmamap_destroy call, respectively. For the sb and ad1848 drivers,
they're deferred until open/close.
All isa_dmamap_create calls can now use BUS_DMA_ALLOCNOW and be done
at attach time.
|
| 1.18 |
| 01-Feb-2003 |
thorpej | Add extensible malloc types, adapted from FreeBSD. This turns
malloc types into a structure, a pointer to which is passed around,
instead of an int constant. Allow the limit to be adjusted when the
malloc type is defined, or with a function call, as suggested by
Jonathan Stone.
|
| 1.17 |
| 26-Jun-2000 |
simonb | 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.
|
| 1.16 |
| 07-Feb-2000 |
thorpej | branches: 1.16.4;
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.
|
| 1.15 |
| 22-Feb-1999 |
mycroft | branches: 1.15.8;
Add support for demand mode with auto-init.
|
| 1.14 |
| 28-Jun-1998 |
thorpej | Add an additional ISA DMA mode: LOOPDEMAND. This is for devices, such
as the Shark's CS8900 Ethernet, which want to use the DMA controller in
this mode (as opposed to single mode).
[Editor's note: committed from a Shark using a new bus_dma back-end
and a CS8900 driver converted to use the MI code :-]
|
| 1.13 |
| 25-Jun-1998 |
thorpej | Don't panic if a DRQ is already allocated. Instead, just return EAGAIN
to indicate that the resource is unavailable.
|
| 1.12 |
| 09-Jun-1998 |
thorpej | Add isa_dma{freeze,thaw}(), used to temporarily stop and then restart
all ISA DMA. Needed by e.g. the SmartCard reader for Sharks.
|
| 1.11 |
| 09-Jun-1998 |
thorpej | 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.
|
| 1.10 |
| 04-Aug-1997 |
augustss | Implement a function to test if a drq is taken and use it
in two drivers. There are still many drivers left to fix...
|
| 1.9 |
| 28-Jul-1997 |
augustss | branches: 1.9.2;
Audio: Remove the machine dependant code I put in audio.c by mistake.
This adds another method to audio_hw_if. Also remove a field from
audio_hw_if that was not read-only.
|
| 1.8 |
| 27-Jul-1997 |
augustss | Changes to the sudio system:
- It is now possible to handle devices that want "looping" DMA,
e.g. the SoundBlaster correctly. The WSS and SB drivers use this.
To do this several new methods were introduced in audio_hw_if.
- Different silence handling (forced by previous change).
- The audio driver can now be mmap()-ed, but due to problems in
the VM system only for writing for now.
- The OSS (Linux) audio emulation takes advantage of some of the
new features.

thorpej | Pull thorpej-bus-dma branch into mainline.
|
| 1.6 |
| 21-Mar-1997 |
mycroft | branches: 1.6.2;
Clean up a bit, and export isa_dmamask() and isa_dmaunmask() interfaces.
|
| 1.5 |
| 21-Mar-1997 |
mycroft | Add an isa_dmacount() function, to get the current residual count on a channel.
|
| 1.4 |
| 01-Mar-1996 |
mycroft | Add support to the ISA DMA framework for auto-initialize mode.
Add experimental SB16 code, disabled for now.
|
| 1.3 |
| 20-Feb-1996 |
mycroft | Move the terminal count check into a separate function.
|
| 1.2 |
| 27-Oct-1994 |
cgd | new RCS ID format.
|
| 1.1 |
| 22-Apr-1994 |
mycroft | Separate DMA functions.
|
| 1.6.2.2 |
| 17-May-1997 |
thorpej | Add isa_dmamem_*() functions, which are wrappers around bus_dmamem_*()
functions, but encapsulate the peculiar memory contraints of the
on-board ISA DMA controller. Devices which use the isa_dma*() functions
should use these for DMA-safe memory manipulation.
|
| 1.6.2.1 |
| 13-May-1997 |
thorpej | Mostly-rewrite, converting the ISA DMA controller driver to be a user
of the bus dma API. A new isa_dma*() function call interface is exported
to drivers that need to use this controller.
|
| 1.9.2.1 |
| 23-Aug-1997 |
thorpej | Update marc-pcmcia branch from trunk.
|
| 1.15.8.1 |
| 20-Nov-2000 |
bouyer | Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
