uwe | Since __INTR_MASK + __EXCEPTION_UNBLOCK is common sequence, provide
__INTR_MASK_EXCEPTION_UNBLOCK combo version that does stc/ldc just once.
|
| 1.21 |
| 04-Feb-2011 |
uwe | __EXCEPTION_ENTRY - "tst" already does logical AND, so shave off extra
"mov" and "and" and just test PSL_MD bit directly.
While here - shuffle around instructions to construct PSL_MD to break
dependencies.
While still here - only interrupt vector uses SSR and SPC as function
args, so don't bother saving them here in r4 and r5. Other vectors
don't need them and interrupt vector can just as well "stc" them
directly before exceptions are enabled.

uwe | branches: 1.16.2; 1.16.4;
Tweak __EXCEPTION_BLOCK so that original SR value is preserved in Rm.
We can then often use just "ldc Rm, sr" instead of matching
__EXCEPTION_UNBLOCK and thus shave off a few instructions.

Merge the ppcoea-renovation branch to HEAD.
This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.
TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.
NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

uwe | Misc comment fixes.
|
| 1.12 |
| 25-Sep-2007 |
uwe | Don't expose asm macros (traditional cpp) to C code (ANSI cpp) so that
we don't have to do weird dances protecting # that indicates asm
immediate operand from being iterpreted as cpp stringification
operator.

uch | Rework interrupt code.
+ Fully utilize SH SR.I[0:3] interrupt level.
+ software interrupt is emulated by TMU1, 2 one shot interrupt.
+ implement generic soft interrupts.
+ implement clockframe correctly.

uch | cosmetic changes, fix comments.
|
| 1.3 |
| 17-Mar-2002 |
uch | kernel stack fix. old code simply P3 address converted to P1, it
caused memory destruction when kernel stack grow over 1 page. new
code use P3 address for kernel stack. but for the sake of debug, P1
kernel stack mode remain.

uch | Move common exception vector and scheduler code to
sh3/sh3/exception_vector.S and sh3/sh3/locore_subr.S. exception
vectors are installed by sh_cpu_init(). machine/locore.S contains
kernel entry, interrupt handler, and some MD code.
