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()

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

3e29947e28 No more HZ; move stacktrace() to library 2008-12-11 14:36:37 +00:00
Ben Gras
825dfb0282 introduce Hz variable that is what used to be the HZ constant. 
default 60Hz of course.
 2008-12-11 14:33:33 +00:00
Ben Gras
4c1ac39678 Changes so the HZ constant isn't needed any more. 2008-12-11 14:27:18 +00:00

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.

034b5c6042 PM_PROC_NR shouldn't be hardcoded as the caller. 2008-12-11 14:18:51 +00:00

66b161238d function to increase process stack (pointer). used by VM to set up large, 
sparse, non-preallocated heap and stack.
 2008-12-11 14:17:45 +00:00

e911d44a5c system image processes with full address space are allowed to have pagefaults. 2008-12-11 14:16:40 +00:00
Ben Gras
c4fb567bd5 . replace HZ by runtime system_hz (sysenv variable 'hz') 
. new flag PROC_FULLVM in table indicating process wants full address
   space (this is then created and managed by VM)
 2008-12-11 14:15:23 +00:00
Ben Gras
afef5e0711 . some flags to <minix/const.h> 
. add system_hz for runtime HZ value

e75e231abc VMCTL_INCSP to increase process stack pointer. 
(Used to change the virtual address of the stack before a process has
started executing.)

682b9a872e . ser_putc() goes to library 
. another cmd for getinfo - obtaining current HZ value
 2008-12-11 14:09:38 +00:00
Ben Gras
ef5b6f8cdf . HZ no longer constant, but settable at boot time; default is DEFAULT_HZ (60) 
. some kernel flags to <minix/const.h>

68d0c4defe - code shared with exec() letting boot-time processes have 
their own fully fledged virtual address space and freeing
   their pre-allocated heap+stack area (necessary to let memory
   driver map in arbitrary areas of memory for /dev/mem without
   sys_vm_map)
 - small optimization preallocating memory on exec
 - finished VR_DIRECT physical mapping code
 2008-12-08 16:43:20 +00:00

f4d0d635fd - hz dynamic 
- new map /dev/video implementation
 - ser_putc into library
