c281867f46Fixed bug relating to FS and MEMORY during startup; Relocated some syslib functions to utils library; Changed location of 'Multiuser startup ..." echo in /etc/rc

f2a85e58d9Various updates. * Removed some variants of the SYS_GETINFO calls from the kernel; replaced them with new PM and utils libary functionality. Fixed bugs in utils library that used old get_kenv() variant. * Implemented a buffer in the kernel to gather random data. Memory driver periodically checks this for /dev/random. A better random algorithm can now be implemented in the driver. Removed SYS_RANDOM; the SYS_GETINFO call is used instead. * Remove SYS_KMALLOC from the kernel. Memory allocation can now be done at the process manager with new 'other' library functions.

308d9a693cprettified rtl driver: . no more kmalloc . no more umaps + physcopies / abscopies . the status register is directly readable from the drivers own address space now, and no physcopy is needed to read it . map+physcopy call combinations are replaced by vircopy calls

d0b5cf84cbUndid usage of vector-copy function. It's a good idea but there's a bug there somewhere. I'll debug first, then recommit.

6d23f072f3Cleaned up src/lib/utils library. Renamed server_ functions to more logical names. All system processes can now either use panic() or report() from libutils, or redefine their own function. Assertions are done via the standard <assert.h> functionality.

447b988154exec now uses phys_zero system call to zero bss segments (instead of using phys_copy to copy zeroes there for every kb), which is a big optimisation in some cases

c977bd8709Added args to lock() and unlock() to tell them apart, for use when lock timing is enabled in minix/config.h.

5a43b84e2dFix for 'the kermit problem' (keyrepeats happening before the keyrepeat timeout). A fix is to treat the alarm and interrupt cases differently and only call the interrupt handler when an actual interrupt has been seen. No apparent adverse effects.
Ben Gras
2005-05-31 15:22:06 +0000
0165662cd9Replaced flagalrm() timers with another technique to check for timeouts. This allowed removing the p_flagarlm timer from the kernel's process table. Furthermore, I merged p_syncalrm and p_signalrm into p_alarm_timer to save even more space. Note that processes can no longer have both a signal and synchronous alarm timer outstanding as of now.

ccd17ecfedNew NOTIFY system call! Queued at kernel. Duplicate messages (with same source and type) are overwritten with newer flags/ arguments. The interface from within the kernel is lock_notify(). User processes can make a system call with notify(). NOTIFY fully replaces the old notification mechanism.

e248f7c1a3If the file (created by setup) exists, use boot parameters from there for the boot floppy instead of copying it from the current root partition. This makes making a boot floppy at installation time before booting from the new system possible (conveniently).
Ben Gras

873e44b41fSome #defines for removing registered irq handler
Ben Gras
2005-05-12 16:07:15 +0000
d0c3e8f818. added rm_irq_handler which un-links an irq handler from the linked list of handlers, callable by irqctl system call . workaround for hanging keyboard bug after shutdown.. if key is pressed during or after shutdown procedure, keyboard stops working. It looks like irq 1 gets stuck high if no keyboard reading is done (e.g. because the irq is masked or tty driver has exited). Workaround is to leave irqs enabled until the last second, and call shutdown() immediately after the last driver has stopped (tty task). This way the chance of an unserviced interrupt occuring is negligible.
