and no longer on IRQ 0-13.
Fixed interrupt levels in amigappc_install_handlers() (IPL_SOFTxxx was very
bad!).
Compilation with all (most?) amiga devices was tested and fixed.
Some smaller fixes.
Status:
With Cybervision64 and A3000 SBIC SCSI (with DMA disabled) the system
reaches multiuser!
Lots of problems left...
- asctime{,_r}, ctime{,_r} may return NULL; document that, and avoid coredumps.
- gmtime{,_r}, localtime{,_r} may return NULL and set EOVERFLOW, document and
set errno.
- when mktime returns (time_t)-1, make it set EOVERFLOW and document it.
XXX: Should be pulled up to 5.x
refers to another "uobj" used to call pgo_get. Revert the wrong assertion
I made. My bad.
(This and pgo_get's possible ERESTART return value check is the only 2 behavioral
changes I made.)
Reported by drochner@, thanks.
sp_tlb_flush_pte_usiii() and switchtoctx_us()/switchtoctx_usiii() and
implement the latter while i'm here. it works ... sometimes i think,
but also sometimes panics/hangs.
- fix a comment in sparc64_ipi_flush_pte_usiii()
- Lower fault routines don't care the vm_anon array found in upper lookup.
Don't pass the pointer down.
- The flag "shadowed" is known when we lookup upper layer. Don't need to
keep in the fault context struct.
- sparc64_ipi_flush_pte() becomes sparc64_ipi_flush_pte_us() and
sparc64_ipi_flush_pte_usiii()
- add some commented out code to disable interrupts and raise the traplevel
in sparc64_ipi_flush_pte_usiii()
- cache_flush_phys() was missing a little of code in the cheetah case
the original values. Pointed out by rmind@, thanks.
In the lower fault case, if (*pgo_get)() can return ERESTART and we should
re-fault for that remains a question. The original code just returned the
error, so keep that behaviour for now. In case (*pgo_get)() really returns
ERESTART, pass EIO to tell the uvm_fault caller that (*pgo_get)() failed.
(As far as I grep callers don't check if the return value is ERESTART or not.
So assuming (*pgo_get)() never returns ERESTART should be a safe bet.)
in a bunch more cases
- make sparc64_ipi_halt_thiscpu() and sparc64_ipi_pause_thiscpu() return void,
their callers never checked anyway.
- remove prototypes for sparc64_ipi_flush_ctx() and sparc64_ipi_flush_all(),
there are no such functions
