CPU_SA110 and CPU_LATE_ABORT.
Updated the CLKF_INTR() macro for changes made to the interrupt system.
Updated some of the CPU ID codes.
Added the CPU ID for the ARM8.
This is for an Acorn A7000 machine with an ARM7500 CPU and no VRAM.
This config should also work for other ARM7500 machines with an
architecture that matches Acorns.
Make fp_reg_t a typedef of fp_extended_precision_t.
Rename the fp_state structure to fpe_sp_state as it describes
the single precision FPE state held in the pcb and is internal to the
kernel.
Define a new fp_state structure that is for user access to the fp
state (e.g. via ptrace()).
the AMD AM53CF94 Enhanced SCSI Controller. The code is based on the
SFAS216 driver as these chips are very similar. There are several
differences but more will follow.
Use definitions from this file for match_podule() rather than hardcoded
values.
Added a routine asc_minphys() in preparation for driver changes when on
card DMA support is added.
Use definitions from this file for match_podule() rather than hardcoded
values.
Reset the interface following a bad packet. This fixes some jams when
the driver failed to recover properly after a bad packet.
podule_data.h instead.
Removed the dead function find_podule().
The 0xf5 entry in the podules chunck directory is now searched for and
the podule description associated with this entry is placed in the
description field of the podule structure.
Generally tidied up all the comments.
- Fix up usage of MBD_ISPID().
- Ensure that we never deal with a NULL proc, and if our proc has
no pcb, punt. Suggested by Gordon Ross.
- Eliminate some redundant NULL pointer checks in the T_MMUFLT cases;
proc0.p_addr is now initialized early, and we make a single test
for sanity at the top of trap() now.
- Initialize proc0.p_addr just after setting up the kernel stack, to avoid
getting NULL pointers in trap(). Change suggested by Gordon Ross.
- Panic if main() returns.
- Tidy up a couple of comments.
(remaps page read/write/cache-inhibit, does write, restores previous
mapping). Kernel text no longer needs to be read/write with DDB/KGDB
is in the kernel.
Based on a similar module written for the Sun3 port by Gordon Ross,
and modified somewhat by me.
