* Make nokqfilter() return the correct return value.Poul-Henning Kamp2003-03-031-1/+1

* Gigacommit to improve device-driver source compatibility betweenPoul-Henning Kamp2003-03-031-14/+10
| | | | | | | | | | | | | | | | branches: Initialize struct cdevsw using C99 sparse initializtion and remove all initializations to default values. This patch is automatically generated and has been tested by compiling LINT with all the fields in struct cdevsw in reverse order on alpha, sparc64 and i386.

| | | | | | | | | | The advanced stage of computer assisted hardware design and verification is aptly illustrated by the fact that this is necessary because only the first ports in a single-chip, dual-port async PC-Card product lacks this register. Notes: svn path=/head/; revision=104067

* 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.

* Support more than 32 sio unit numbers. The maximum unit number is nowBruce Evans2002-03-311-8/+12
| | | | | | | | | | | | | | (65536 * 32 - 1), but MAKEDEV only supports up to (32 * 32 -1). Device names use the unit number in base 32 for all "digits". This required fixing an old bug in MAKEDEV:ttyminor(). Its arg was the global $unit instead of $1. Reminded by: Valentin K.

* 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).

Later pci parallel ports could also be supported through this driver.

* While I'm not sure that I like the wording of the BIOS message in theWarner Losh2002-01-171-1/+2
| | | | | | | | | | | | | previous commit, it should always print due to lack of {} around the second line in the if statement. 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
