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

866a4a667e phys addr arg of 0 must be possible for pt_writemap too (instead of meaning 
unmap).

b740ff055f if serial output is enabled in the boot monitor, on the first serial line, 
enable serial debug output in the kernel too.

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.

f0000078c3 make kernel leave a page-sized gap in its code and data to not be 
mapped in if so configured.

8beff61807 get fproc table. don't print size as that doesn't say much in VM mode. 
this restores ps.

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)

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.

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

825dfb0282 introduce Hz variable that is what used to be the HZ constant. 
default 60Hz of course.

5aea2817bc syslogd needs a bit more stack. 2008-12-11 14:26:27 +00:00
Ben Gras
9d096e014b . print kernel stacktrace unconditionally on panic 
. provide a panic() in the kernel for if a library function wants to panic
 2008-12-11 14:23:58 +00:00
Ben Gras
b61687fb1b . VM needs a higher priority than VFS, PM etc 
. introduce FULLVM flag: MEMORY and the initial MFS
   get their own full address spaces, making their stacks
   and heaps not preallocated (well, freed after VM has
   initialized it) and letting them allocate more dynamically.
   MEMORY in particular needs this to map in physical memory
   using its own page table, without having to allocate.
