command not found. Add extra exception type and generalize
error handling routines to take that exception type. Use
a global variable exerrno to keep the last exec error.
* kill scc_tty[] and needs-count.
* Add usable-when-cold version of sccparam().
* Add pre-autconf() console initialization entrypoint.
* remove lint for gcc -Wall
* wbflush() -> tc_mb()
all but the last of which have been fed through cgd and committed to the
Alpha scc driver.
code as video memory must be reserved from main memory for the display.
In addition this adds generic support for using DRAM for video memory
on all machines. All video memory accessing should use the video_memory_t
structure.
Added support for the RC7500 motherboard. The RC7500 support includes a
replacement init_arm() function. This also supports the RC7500 prom debug
monitor for debugging the kernel boot.
dumps now work so call dumpsys() following a panic.
Added support for the SA110. This mainly consists of making sure the data
cache is cleaned when appropriate and that the instruction cache is
kept in sync during the bootstrap and when signal handlers are built on
the stack.
Use a larger UND32 mode stack if we are configured for KGDB.
Remove KERNEL_PT_KSTACK references as these should have died with the
removal of double mapped kstacks eons ago.
Make sure we call doshutdownhooks() if boot is called while we are still
cold.
Cleaned up prototypes declarations.
Sorted out comment indentation.
to wake up. This is needed because the active filter applied in user
space may fail to match VJ compressed packets. (The kernel applies its
copy of the filter before it runs VJ compression.)
autoconfiguration. It clears the RPB's per-cpu-slot BIP flag and
sets up the RPB's restore_term and restart vectors, etc. add a
console_restart() function, which causes a panic and system dump,
that is invoked (indirectly) via those vectors.
eventually, the restart HWRPB vector), which calls console_restart. This
is invoked when the console halt switch is used and the user enters 'c'
at the console prompt, and eventually causes a system crash dump to be
generated.
clean and tlb flush code along with write buffer drains that are
dependant on the definition of CPU_SA110.
The memory reserved for the L1 pagetables is now wired into the memory map
during the pmap_init rather than at L1 pagetable allocation time.
The L1 pages tables are zeroed during initialisation and when they are
released rather than when they are allocated.
When searching for a free L1 page table start search at the page table
after the last one allocated rather than always starting from the first one.
Added some extra DIAGNOSTIC checks for invalidate page index numbers.
Removed some old debugging code that escaped the last clean up.
Idented comments in line with code.
