* Change the suser() API to take advantage of td_ucred as well as do aJohn Baldwin2002-04-011-3/+3
| | | | | | | | | | | | | | | general cleanup of the API. The entire API now consists of two functions similar to the pre-KSE API. The suser() function takes a thread pointer as its only argument. The td_ucred member of this thread must be valid so the only valid thread pointers are curthread and a few kernel threads such as thread0. The suser_cred() function takes a pointer to a struct ucred as its first argument and an integer flag as its second argument. The flag is currently only used for the PRISON_ROOT flag.

* Hacks for measuring interrupt latency. Interrupt latency can beBruce Evans2002-03-311-2/+42
| | | | | | | | | | | | | | | | | measured accurately for periodic interrupts provided the interrupts don't need to be serviced very quickly to keep their period almost constant. sio output interrupts have this property (interrupt service can be delayed for up to 1 character time without the period changing). This is non-optional and undocumented so that it can be added and removed easily. It has no significant effect unless it is enabled by hacking on a variable using a debugger. Hardclock and statclock interrupts would work even better for this, at least on i386's, provided their interrupt handlers are fast (as they are in -current but not in -stable or in my version of -current).

| | | | | | | | | | | | | | | | the structure definitions come from NetBSD to make it easier to share card definitions. The driver only acts as a shim between the pci bus and the sio driver. Later pci parallel ports could also be supported through this driver.

The message should likely say something more like "There's no hardware responding at this IRQ. Device not present (or disbaled)," but that is too long. We generally don't give elementary advise in device driver messages anyway. Be that as it may, the problem with it printing all the time should be corrected. Notes: svn path=/head/; revision=89463

* Change the preemption code for software interrupt thread schedules andJohn Baldwin2002-01-051-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mutex releases to not require flags for the cases when preemption is not allowed: The purpose of the MTX_NOSWITCH and SWI_NOSWITCH flags is to prevent switching to a higher priority thread on mutex releease and swi schedule, respectively when that switch is not safe. Now that the critical section API maintains a per-thread nesting count, the kernel can easily check whether or not it should switch without relying on flags from the programmer. This fixes a few bugs in that all current callers of swi_sched() used SWI_NOSWITCH, when in fact, only the ones called from fast interrupt handlers and the swi_sched of softclock needed this flag. Note that to ensure that swi_sched()'s in clock and fast interrupt handlers do not switch, these handlers have to be explicitly wrapped in critical_enter/exit pairs. Presently, just wrapping the handlers is sufficient, but in the future with the fully preemptive kernel, the interrupt must be EOI'd before critical_exit() is called. (critical_exit() can switch due to a deferred preemption in a fully preemptive kernel.) I've tested the changes to the interrupt code on i386 and alpha. I have not tested ia64, but the interrupt code is almost identical to the alpha code, so I expect it will work fine. PowerPC and ARM do not yet have interrupt code in the tree so they shouldn't be broken. Sparc64 is broken, but that's been ok'd by jake and tmm who will be fixing the interrupt code for sparc64 shortly. Reviewed by: peter Tested on: i386, alpha Notes: svn path=/head/; revision=88900

* Fixed locking bugs in rev.1.346:Bruce Evans2001-12-281-2/+6
| | | | | | | | | | | | | | | | | | (1) Don't attempt aquire the non-recursive lock sio_lock recursively. Doing so caused unbounded recursion in some setups. E.g., if DDB, BREAK_TO_DEBUGGER and WITNESS are configured; if the debugger is entered using a break, then WITNESS will actually detect the invalid recursion and will add to it attempting to print a message about it. (2) Don't use sio_lock before it has been initialized. The old check (sio_inited != 0) didn't work when sio_inited was boolean because sio_inited was set too early, and became just wrong when sio_inited was changed to a tri-state variable in rev.1.348.
