jake	a065785f57	Greatly improve readability of trap() by using a table to convert between ... trap types and signals to send. Rearrange KASSERTs to better handle faults early before curthread is setup, or in the case that it gets corrupted or set to 0.	2002-10-25 16:00:47 +00:00
jake	42ab31b72d	Add a panic stack, which is used as a known good stack when there is ... something wrong with the kernel stack. Add code to check the kernel stack pointer in various important places and try hard not to go down in flames if its wrong.	2002-01-01 20:26:46 +00:00
jake	2b14434bd9	Rename and renumber trap types to comply with the user trap types as ... specified by the sparc abi. We use numerically higher values for all internal kernel types. Remove soft trap types which need to be exposed to userland. They will move to utrap.h.	2001-12-29 07:09:50 +00:00
jake	cb7ca29ccf	Add support for physical address hardware watchpoints.	2001-10-20 16:04:39 +00:00

jake	f9d393e059	Change tf_arg to uintptr_t from void * to reflect the fact that ... non-pointer values may be passed in it. Add appropriate casts. The interrupt type is now passed in tf_arg instead tf_type.	2001-09-03 23:13:42 +00:00
jake	c5b148f1dd	Add a system call trap type and syscall() call request handler. ... Also add support for hardware watch point traps. Submitted by: tmm	2001-08-20 23:43:43 +00:00

jake	fb7edc502f	Flesh out the sparc64 port considerably. This contains: ... - mostly complete kernel pmap support, and tested but currently turned off userland pmap support - low level assembly language trap, context switching and support code - fully implemented atomic.h and supporting cpufunc.h - some support for kernel debugging with ddb - various header tweaks and filling out of machine dependent structures	2001-07-31 06:05:05 +00:00
