rmixl_intr_string()
- in rmixl_pcix_intr_establish(), initialize dispatch data 'counts' pointer
- in rmixl_pcix_pip_add_1(), zero out pip_new after allocated.
- add rmixl_eirr_ack() to ack the EIRR, using COP0_SYNC & JR_HB_RA as needed
- in rmixl_cpu_trampoline, remove old KSEG0 address reconstruction
of trampoline args pointer, and comment/explain the new way
- also in rmixl_cpu_trampoline, remove old watchpoint hack used for debugging
- add COP0_SYNC and JR_HB_RA following CP0 after all
writes to STATUS or EIMR that change interrupt control.
- all interrupt control now done w/ EIMR, except for
initial set of IE in STATUS.
to ack the EIRR, instead of using a bunch of asm() here.
- in rmixl_ipi_intr(), remove overly paranoid assert that the given
IPI request is pending; if the request is clear, it was previously processed.
- in rmixl_vecnames_common[], give ipi vectors unique (numbered) names
initializations once we know what threads are configured
- add sc_threads_enb and sc_threads_dis to track what threads are
enabled by firmware and configured and attach, or not.
- add prototype for cpucore_rmixl_run()
enabled by firmware and configured and attach, or not.
- add cpucore_rmixl_run() to do the post-running initialization:
disable unused threads in RMIXL_PCR_THREADEN, and
set Round Robin thread scheduling mode.
to be called from cpu_hatch() once cpus are running,
so we can determine what threads are configured
and running, and can finish initialization of per-core registers
depending on that.
- in cpu_rmixl_db_watch_init() clear IEU_DEFEATURE[DBE],
and init all COP0 watchpoint regs
- option MIPS_DDB_WATCH is deprecated, removed; use of cpu watchpoints
is longer depends on that or DDB
(MIPS32 + MIPS32R2 + MIPS64 + MIPS64R2) > 0 for conditional
compile of db_mach_watch stuff
- MIPS CPU (COP0) watchpoint support moved from db_interface.c
to cpu_subr.c, cpu.h; ddb_mach_watch &etc now use those cpu functions.
- ddb_cpu now volatile
- 'struct db_mach_watch' definition &etc moved to mips/include/db_machdep.h
- db_mach_watch_tab is replaced by curcpu()->ci_watch_tab
to allow per-cpu watchpoint control
- improve MP function in kdb_trap()
- fix conditions for printing cp0 regs
see the cpuwatch_* functions
- ci_cpuwatch_count in allocated cpu_info is inherited from cpu_info_store
- cpu_hatch() calls lsw_cpu_run (if not NULL)
to optionally allow running MIPS chip-specific code
after subordinate cpus have been set running
- #ifdef DDB cpu_debug_dump() to allow compile when DDB not defined
so that we include the source tree's sys/, machine/ and m68k/ headers,
and only as a last resort use DESTDIR's /usr/include. For some reason
the host's bootinfo.h got included ahead of the x68k variant, causing
a build failure in my case.
promlib.h. put db_read/write_bytes() under _KERNEL.
XXX: for now, provide an empty db_machine_command_table[].
XXX2: this file puts a lot of it under #ifdef DDB, but i'm not sure
why this is done. for now it makes it easier to port to userspace :)
ULOAD(). implement KLOAD() in terms of db_read_bytes() in userspace.
can't use proc_find_raw() in userspace; disable this functionality
for now. use db_printf().
(we could avoid this, but it would require a lot of contortions that
make the header files ugly. maybe someone else can figure out a less
ugly way of doing this later.)
