Lets users over-ride with makeoptions COPTS="..." in kernel config files.
Leave `mandatory' flags (like -msoft-float which on m68k enforces no
FP in kernel) in CFLAGS.
to initialize conspa was invalid on non-040 machines, since we don't
know which MMU we're using on those, yet. On the other hand, by the time
we get to check_video() on the 040 machines, the MMU has been disabled.
Compromise: get the video PA in setmachdep() on the 040, and in
check_video() on the others. (This is not optimal. *sigh*)
- Add reset attribute sequences for bold, underline, and reverse
- Add insert/delete line sequences
- Recognize but ignore G0/G1 character set sequences
Performance:
- Speed up clear_line() when clearing the entire line
Also, some stylistic changes for checking/setting scroll region bounds
and in putc_getpars().
These changes make the ITE work properly with the 1.2 termcap file.
have an Apple Sound Chip. Make sure that we have configured the device
before allowing accesses to ASC memory. Among other things, this
prevents the 660AV and 840AV from getting a kernel bus error when trying
to beep on the console.
instead of 0x400.
- Restructure interrupt handling for more performance--continue to
read/write data as long as the device keeps us in a data xfer phase.
There is still a lot of room for speed improvement here. Perhaps it
lies is speeding up the interrupt path in general?
some guesses for the machines that have two of these buggers (I don't have
such a machine). This driver is a copy of the sparc/alpha esp with a
minimum of changes--after we get it performing a bit more respectably,
we should see about re-normalizing the sources.
- Fix up usage of MBD_ISPID(). (from Jason Thorpe)
- Be careful not to deref bad pointers in the MMU fault handler. (ditto)
- Ensure trap() never deals with a NULL proc, and if our proc has
no pcb, punt. (Suggested by Gordon Ross)
- 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.
immediately reasserted before we get a chance to process the interrupt,
we can inadvertantly get stuck with zs_tx_stopped set. Move the delta
detection to the hard zs interrupt handler; the softint handler
will notice that something has happened with CTS and restart the
transmitter if it's asserted.
brings us closer to basic operation.
- Verified/updated ROM vector entries for many systems, and new vector
table entries for LC 520, LC 575/577/578, and Quadra 950
- Implement a new machine class (MACH_CLASSQ2) for the LC 575 series
- Use the ptest040() helper function in get_physical().
Also, in straytrap(), only enter the debugger #ifdef DDB.
