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.

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.

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.
1998-01-23 00:44:02 +00:00
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.

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.

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.
