Ben Gras 128a0508c0 timing measurement code out of kernel and into library 
(so other components can use it too)
 2009-01-09 16:15:15 +00:00

are opened.
 2008-12-21 04:01:01 +00:00
Ben Gras 0579810535 don't ignore the fact that scancodes are escaped. 
if not understood explicitly, print diagnostic and 
ignore scancode.

Ben Gras 23a158b361 don't check senda() buffer if size is 0. 2008-12-21 03:46:42 +00:00
Ben Gras 203eb54a4c make space for first code and data pages if so configured. 2008-12-19 15:46:29 +00:00
Ben Gras d2757d4b73 debug buffer slightly usabler. 2008-12-19 15:19:42 +00:00
Ben Gras 866a4a667e phys addr arg of 0 must be possible for pt_writemap too (instead of meaning 
unmap).
 2008-12-19 13:29:12 +00:00
Ben Gras b740ff055f if serial output is enabled in the boot monitor, on the first serial line, 
enable serial debug output in the kernel too.

Ben Gras 7fdc181d5f /boot/boot install helper script. 2008-12-19 12:52:45 +00:00
Ben Gras 8072ef5509 oops, shouldn't be on in svn. 2008-12-18 17:42:29 +00:00
Ben Gras 3121eec6bd . map text (kernel's and processes') in readonly 
. map kernel in non-user
 . don't map in first pages of kernel code and data
   if possible

these first pages could actually be freed but as the
kernel isn't allowed to touch them either we can't reuse
them until VM has totally taken over page table management
and kernel doesn't rely on identity mapping any more.
 2008-12-18 15:35:22 +00:00
Ben Gras f0000078c3 make kernel leave a page-sized gap in its code and data to not be 
mapped in if so configured.

Ben Gras a306c63e0b 2008-12-15 15:16:26 +00:00
Ben Gras 8beff61807 get fproc table. don't print size as that doesn't say much in VM mode. 
this restores ps.
 2008-12-15 13:05:52 +00:00
Ben Gras e4e3995fb0 don't force vm to print to serial; don't kill processes when they 
have 'bad' memory ranges (as it's the requestor's fault)
 2008-12-11 17:36:33 +00:00

Ben Gras b6b361a474 rc script needs to open its own stdin, stdout and stderr 2008-12-11 14:50:56 +00:00
Ben Gras 011de3ac49 everyone needs GETINFO for HZ 2008-12-11 14:50:28 +00:00
Ben Gras 2024bf0bcf . no more HZ 
. let user processes query HZ
 . no more custom panic()
 2008-12-11 14:49:17 +00:00
Ben Gras ccf70aa989 system_hz replaces HZ 2008-12-11 14:48:05 +00:00

Ben Gras eeba8ef01f No more HZ. 2008-12-11 14:43:53 +00:00
Ben Gras e9f0c576a3 Open stdin, stdout and stderr only after /etc/rc has executed. (/etc/rc 
executes it itself.) This avoids keeping /dev nodes on the temporary
root filesystem (initial mfs) in use unnecessarily.
 2008-12-11 14:43:25 +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
 2008-12-11 14:42:23 +00:00
