Ben Gras 59e972f074 let drivers allocate memory at 64k physical boundary. 2009-02-12 12:26:08 +00:00
Ben Gras 6ac0338584 Don't declare the cprof buf if CPROFILE isn't on. 2009-02-06 16:31:28 +00:00
Ben Gras b696823379 stingy stack. 2009-02-06 16:29:00 +00:00
Ben Gras 95ff97d4fb readclock easily runs out of stack with so little of it. 2009-02-06 16:28:35 +00:00
Ben Gras eafd4730ea check for devices that would need more blocks than 32 
bits allow..

Ben Gras 6e86e6706d fix compiler warning; missing memory range check 2009-02-05 13:00:03 +00:00
Ben Gras bb18be5d06 simplified the code a little, corrected some hasty statements. 2009-02-04 17:30:01 +00:00
Ben Gras 6a0e8e3b80 Added a separate keymap for escaped scancodes. This makes the code 
a little cleaner (escaped scancodes are less of a special case) and
lets us be completely flexible when assigning meaning to them.

Future: a tool and ioctl to load the escaped keymap.
 2009-02-04 17:04:16 +00:00
Ben Gras ba4687e519 the escaped keymap is usually the same as the original. 2009-02-04 16:55:30 +00:00
Ben Gras 113932905f disable interrupts if necessary in kernel debug code to dump all process 
stacks.
 2009-01-29 15:13:54 +00:00
Ben Gras 80f5eea8b8 If serial debugging in the boot monitor / kernel is enabled, don't touch 
the serial line in use for it (mostly so that input isn't eaten by tty).
 2009-01-29 15:06:40 +00:00
Ben Gras d0a2e6b2f4 use library panic, doesn't need its own any more. 2009-01-29 14:41:44 +00:00
Ben Gras c628f24bc2 moved stacktrace to sysctl, as vmctl is very privileged so can't 
be used outside VM. IS code cleanup. added stacktrace feature to IS.
 2009-01-27 12:54:33 +00:00
Ben Gras 3cc092ff06 . new kernel call sysctl for generic unprivileged system operations; 
now used for printing diagnostic messages through the kernel message
   buffer. this lets processes print diagnostics without sending messages
   to tty and log directly, simplifying the message protocol a lot and
   reducing difficulties with deadlocks and other situations in which
   diagnostics are blackholed (e.g. grants don't work). this makes
   DIAGNOSTICS(_S), ASYN_DIAGNOSTICS and DIAG_REPL obsolete, although tty
   and log still accept the codes for 'old' binaries. This also simplifies
   diagnostics in several servers and drivers - only tty needs its own
   kputc() now.
 . simplifications in vfs, and some effort to get the vnode references
   right (consistent) even during shutdown. m_mounted_on is now NULL
   for root filesystems (!) (the original and new root), a less awkward
   special case than 'm_mounted_on == m_root_node'. root now has exactly
   one reference, to root, if no files are open, just like all other
   filesystems. m_driver_e is unused.
