332d7c138f Avoid arithmetic on `void *' since that's not ANSI C. 1999-01-08 18:10:35 +00:00

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.

6d29690288 Implement bounce buffers for mbufs. 1998-06-03 21:50:48 +00:00

051c391187 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.

99cc8482d1 Change the last argument of bus_dmamap_sync() from bus_dmasync_op_t to int, 
and allow more than one synchronization operation to be specified in
a single call.  Dissallow mixing of PRE and POST operations.

22c1670658 Some rearrangement of the startup code: 
* Move some of the memory bootstrapping and the DDB startup earlier.
* Always put the IDT and the initial GDT and LDT in a separate page.
* Various minor changes.

6a310175c6 Some general cleanup: 
* Call gdt_init() earlier on.
* Don't bother to check for TSS and LDT descriptors in verr_gdt().
* Nuke the sti special case for trace and breakpoint traps.
* Move some variable declarations into more appropriate locations.

799112abbe Pull down from marc-pcmcia branch: 
Implement new ISA interface functions:
* isa_intr_alloc() - allocate an ISA IRQ
* isa_mem_alloc() - allocate ISA memory space
* isa_mem_free() - free ISA memory space

b2038a332d Import interrupt priority changes from com patches: 
* Make it a strict hierarchy.  (It was close anyway).
* Add `serial' and rename `softtty' to `softserial'.
* Make soft interrupts a bit less special-case.

9a6796b559 In isa_attach_hook(), set a variable to indicate that an ISA bus has 
been attached to the system.  If, by the time mainbus wants to attach
an ISA an ISA has not yet been attached to the system, attempt to attach
an ISA to mainbus.

3da4b2a160 The IST_* and IPL_* constants are not bus-specific; don't treat them as such.

8096b83664 Eliminate soft segment descriptors; instead use a functional interface for 
creating segment descriptors.  Add the duplicate system call gate used by
BSD/OS 2.0 executables.  Prototype setsegment() and setgate(), and fix a bogon
caught by this.
