The IDT is an array of struct gate_descriptor.
2003-03-03 22:16:20 +00:00

The IDT only contains gate descriptors, so define it as such.

define pmap_cpu_has_pg_n and pmap_cpu_has_invlpg to make code sharing

easier.
2003-03-03 22:13:16 +00:00

Make CVAR asm reference macro CVAROFF, taking an offset.

Change the pmap to use 512-byte pages as user page table pages instead of
...
PAGE_SIZE pages (4k). An average small program uses ~6 4k pages (24k),
while the same program only uses ~20 512 byte pages (10k), so it will be
a small memory usage improvement. The large improvement will be the upcoming
ability to share page table pages between processes for shared libraries.
Remaining: should be able to give back ptp pages to the system.

add some ISO C 1995 I18N functions and types:

btowc, wctrans, towctrans, wcscoll, wcsxfrm, wctype_t and wctrans_t.

Use the new pmap_kprotect() function instead of pmap_changeprot().
...
The latter is now a pmap internal function; and it wasn't used correctly
in mkclock.c anyway.
2003-03-02 21:42:48 +00:00
22cf03a09f
pmap_changeprot() is not a UVM <-> PMAP interface function; make it internal.
...
Provide pmap_kprotect() for MD code to change protection on a range of
kernel addresses (cuurent users: intr.c and mkclock.c).

Clean up some unneeded "mca.h" and "eisa.h" includes, make one that is

needed dependent on !__x86_64__. To be revisited later.
2003-03-02 18:27:14 +00:00

x86_64 has no mca.h and eisa.h (should perhaps just generate empty ones)

Cleanup G2_LOCK/G2_UNLOCK macros per discussion on port-dreamcast:
...
- Use _cpu_intr_suspend()/_cpu_intr_resume() in G2_LOCK/G2_UNLOCK macros
rather than _cpu_exception_suspend()/_cpu_exception_resume().
TLB miss exceptions could happen on accessing buffer, but it will never
block G2bus cycle anyway.
- Restore the previous SR.IMASK value in G2_UNLOCK().
- some misc cosmetics.
Should fix spontaneous reboots by "ping -s 8192 host" on the LAN Adapter.

Follow the spec more closely, and do an ljmp immediately after enabling

This was still falsely referencing the ipending variable, which isn't
...
used anymore. Use curcpu()->ci_ipending (== cpu_info_primary.ci_pending,
since this is only used in the UP case).

Add support for large kernels by searching for a physical memory segment
...
to fit it in. As a bonus, the kernel is now also mapped to the virtual
address (i.e. KERNBASE) it is linked at.
2003-03-01 13:01:55 +00:00

Do the syscall_plain/syscall_fancy dance on ARM. Shaves a fair number
...
of cycles off the syscall overhead.
Since all COMPAT_LINUX platforms now support __HAVE_SYSCALL_INTERN,
garbage-collect the LINUX_SYSCALL_FUNCTION stuff.

Move the -D__daddr_t from libsa/Makefile to Makefile.booters so

the bootloaders get to benefit from it, not just libsa.

Make BRIDGE_IPF an option, and document it. Add it (commented) to GENERIC.
