5a02e1abe2 Adjust the check for what segments should go on the low priority free list. 
If a segment starts exactly at 16M don't try to split it because that causes
the code to try to call uvm_page_physload with a zero length segment.

fd955ca5d6 Make it plain to the compiler that __sigtramp_sigcontext_1() really is 
an external function, instead of an array. Otherwise, it won't set
bit 0 of the trampoline's address to indicate SHmedia mode.

1e06edb63b There is no need to do an imb after each call to the binder, because we only 
patch the GOT, not the PLT.  However, do an imb when setting up the PLT thunk,
just in case.

937e5f4f83 Previous commit broke the normal build; this should really fix the 
problem, toolchain/18020. From Frederick Bruckman <fredb@immanent.net>.

a9cd647f4d Adapt to recent sbusvar.h changes.

dd3511071d Mondo pmap fixes, including a bunch of DEBUG stuff. 
This still needs a bunch of work, but is good enough to get
us to single-user mode.

To paraphrase a quote from Short Circuit: "NetBSD/sh5 is alive!".

4b8905020d - #define the physical start of RAM. 
- Set up a Panic Stack,
 - Don't pre-map the sysfpga at this time.
 - Calculate the CPU speed only if SH5_CPU_SPEED isn't defined.
 - On a related note, make the CPU speed probing code more accurate.
 - Print the CPU speed at startup.
 - Force RB_SINGLE for now, at least until I get a bootloader written.

e94347123e Set SMC_FLAGS_32BIT_READ flag before calling the MI code. 2002-09-04 14:55:42 +00:00
scw
0dbf19c561 Add a flag, SMC_FLAGS_32BIT_READ, which is settable by the bus-specific 
back-end to indicate that the device always sees reads as 32-bit
transactions, even if the host does 8 or 16-bit reads.

This is necessary for the SH-5 "Cayman" on-board ethernet. The SMsC part
is behind an FPGA which maps all cpu reads to 32-bits transactions.

7f0cd9b561 Some bug fixes: 
- in _EXCEPTION_EXIT, copy the current ASID to the pre-exception
    context before we switch.
  - fix the pteg hash generation code and EPN masking in the tlb
    miss handler.

Sprinkle some DIAGNOSTIC checks.

8f18047310 Fix a couple of bugs:

 - advance the PC to the next insn before dealing with a syscall (trapa)

5496168b35 In setregs(), set SF_FLAGS_CALLEE_SAVED in the new process' trapframe 
to ensure the callee-saved set will be restored when we switch to it.
(It doesn't actually matter to the new process; it just inherits some
crud in those registers from the kernel if we don't set the bit).

Also ensure the strings pointer in r7 is sign-extended.

adaa2cbf20 Don't bother setting SR.BL before double-checking a TLB entry. It's 
sufficient just to set SR.IMASK to 0xf (which also allows single-
stepping through the code).

8b01de5e08 Commit with correct RCS IDs in these files - hadn't looked into them 
previously to note that they reference the RCS ID in "pcmciadevs".
Hence, committed versions which incorrectly pointed back to the RCS ID
of the "pcmciadevs" that existed prior to my addition. Corrected in this
commit.
