* - Add a hack for "psmintr: out of sync.." This is NOT a fix,yokota2000-12-011-0/+11
| | | | | | | | | | | but a hack! Add `flags 0x8000' to the psm driver to enable it. The psm driver will try to get out of out-of-sync situation by disabling the mouse and immediately enable it again. If you are seeing this out-of-sync problem because of an incompetent(?!) KVM switch, this hack will NOT be good for you. However, if you are occasionally seeing the problem because of lost mouse interrupt, this might help.

* - Overhaul the software interrupt code to use interrupt threads for eachjhb2000-10-252-16/+16
| | | | | | | | | | | | | | | | | | | type of software interrupt. Roughly, what used to be a bit in spending now maps to a swi thread. Each thread can have multiple handlers, just like a hardware interrupt thread. - Instead of using a bitmask of pending interrupts, we schedule the specific software interrupt thread to run, so spending, NSWI, and the shandlers array are no longer needed. We can now have an arbitrary number of software interrupt threads. When you register a software interrupt thread via sinthand_add(), you get back a struct intrhand that you pass to sched_swi() when you wish to schedule your swi thread to run. - Convert the name of 'struct intrec' to 'struct intrhand' as it is a bit more intuitive. Also, prefix all the members of struct intrhand with 'ih_'. - Make swi_net() a MI function since there is now no point in it being MD. Submitted by: cp

| | | | | | | | | | | | | | | | | | | | | | | | | | | | return through doreti to handle ast's. This is necessary for the clock interrupts to work properly. - Change the clock interrupts on the x86 to be fast instead of threaded. This is needed because both hardclock() and statclock() need to run in the context of the current process, not in a separate thread context. - Kill the prevproc hack as it is no longer needed. - We really need Giant when we call psignal(), but we don't want to block during the clock interrupt. Instead, use two p_flag's in the proc struct to mark the current process as having a pending SIGVTALRM or a SIGPROF and let them be delivered during ast() when hardclock() has finished running. - Remove CLKF_BASEPRI, which was #ifdef'd out on the x86 anyways. It was broken on the x86 if it was turned on since cpl is gone. It's only use was to bogusly run softclock() directly during hardclock() rather than scheduling an SWI. - Remove the COM_LOCK simplelock and replace it with a clock_lock spin mutex. Since the spin mutex already handles disabling/restoring interrupts appropriately, this also lets us axe all the *_intr() fu. - Back out the hacks in the APIC_IO x86 cpu_initclocks() code to use temporary fast interrupts for the APIC trial. - Add two new process flags P_ALRMPEND and P_PROFPEND to mark the pending signals in hardclock() that are to be delivered in ast().

* - Heavyweight interrupt threads on the alpha for device I/O interrupts.jhb2000-10-052-7/+1
| | | | | | | | | | | - Make softinterrupts (SWI's) almost completely MI, and divorce them completely from the x86 hardware interrupt code. - The ihandlers array is now gone. Instead, there is a MI shandlers array that just contains SWI handlers. - Most of the former machine/ipl.h files have moved to a new sys/ipl.h. - Stub out all the spl*() functions on all architectures.

| | | | | | | | | | | | | | | | | | cloning infrastructure standard in kern_conf. Modules are now the same with or without devfs support. If you need to detect if devfs is present, in modules or elsewhere, check the integer variable "devfs_present". This happily removes an ugly hack from kern/vfs_conf.c. This forces a rename of the eventhandler and the standard clone helper function. Include <sys/eventhandler.h> in <sys/conf.h>: it's a helper #include like <sys/queue.h> Remove all #includes of opt_devfs.h they no longer matter.

With these changes it is possible to cleanly support machines which have more than one independantly numbered PCI busses. As a bonus, the new busspace implementation should be measurably faster than the old one.

Use correct uid, gid & mode in make_dev in disk minilayer. Add support for registering alias names for a dev_t using the new function make_dev_alias(). These will show up as symlinks in DEVFS. Use makedev() rather than make_dev() for MFSs magic devices to prevent DEVFS from noticing this abuse. Add a field for DEVFS inode number in dev_t. Add new DEVFS in fs/devfs. Add devfs cloning to: disk minilayer (ie: ad(4), sd(4), cd(4) etc etc) md(4), tun(4), bpf(4), fd(4) If DEVFS add -d flag to /sbin/inits args to make it mount devfs. Add commented out DEVFS to GENERIC
