Ben Gras dd56aa321f to let tty run with its own page table (instead of with the kernel identity 
map table), make it map in video memory.

sadly, this breaks tty in non-paged mode.

happily, this simplifies the code by throwing out the messing
around with segments, and throws out vidcopy.s.

Ben Gras 9647fbc94e moved type and constants for random data to include file; 
added consistency check in random; added source of randomness
internal to random using timing; only retrieve random bins that are full.

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.

Ben Gras ba4687e519 the escaped keymap is usually the same as the original. 2009-02-04 16:55:30 +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).

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.

Ben Gras 0579810535 don't ignore the fact that scancodes are escaped. 
if not understood explicitly, print diagnostic and 
ignore scancode.

Ben Gras ef812af5a6 use VM functions to allocate ramdisk on demand. some unification in code. 2008-12-11 17:33:13 +00:00
Ben Gras 1d8aed840c . no more HZ, but use sys_hz() to get that value 
. memory maps in physical memory (for /dev/mem) with new vm interface
 . pci complete_bars() seems to be buggy behaviour sometimes
 . startup script opens its own stdout, stderr and stdin so init doesn't
   have to do it
