* Converted the isa probe and attach to new-bus so that this driver worksbde2004-04-053-92/+164
| | | | | | | | | | | | | | | | | | | | | without the (defunct) isa compatibility shims. The new-bus-specific parts are very similar to the ones for the pci probe and attach. This was held up too long waiting for a repo copy to src/sys/dev/cy, so I decided to fix the files in their old place. This gives easier to read and merge diffs anyway. The "count" line in src/sys/conf/files won't be changed until after the repo copy, so old kernel configs that specify a count need not be (and must not be) changed until then. The count is just ignored in the driver. One unfinished detail is dynamic allocation of arrays with <count> and (<count> * 32) entries, and iteration over the arrays. This is now kludged with a fixed count of 10 (up to 10 cards with up to 32 ports each). Prodded by: imp Submitted by: mostly by imp Approved by: imp
* Moved initialization of the lock from the (isa) probe function to thebde2004-04-052-12/+12
| | | | | | | common attach function so that the lock gets initialized in all cases. This fixes breakage of the initialization of the lock in the pci case in rev.1.135 (between the releases of 5.1 and 5.2). The lock is only used in the SMP case, so this bug was not always fatal.
* Device megapatch 4/6:phk2004-02-212-2/+4
| | | | | | | | Introduce d_version field in struct cdevsw, this must always be initialized to D_VERSION. Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.
* Device megapatch 3/6:phk2004-02-212-6/+0
| | | | | | | | | | | | Add missing D_TTY flags to various drivers. Complete asserts that dev_t's passed to ttyread(), ttywrite(), ttypoll() and ttykqwrite() have (d_flags & D_TTY) and a struct tty pointer. Make ttyread(), ttywrite(), ttypoll() and ttykqwrite() the default cdevsw methods for D_TTY drivers and remove the explicit initializations in various drivers cdevsw structures.
* Device megapatch 1/6:phk2004-02-212-4/+0
| | | | | | | Free approx 86 major numbers with a mostly automatically generated patch. A number of strategic drivers have been left behind by caution, and a few because they still (ab)use their major number.

* Fixed breakage of the pci case of the cy driver by the new interruptbde2003-12-023-79/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | code. Both the driver and the new code were wrong. Driver interrupt handlers are supposed to take "void *vsc" arg, but some including all COMPAT_ISA drivers and the pci part of the cy driver want an "int unit" arg. They got this using bogus casts of function pointers which should have kept working despite their bogusness. However, the new interrupt code doesn't honor requests to pass an arg of ((void *)0), so things are very broken if the arg is actually a representation of unit 0. The fix is to use a normal "void *vsc" arg for the pci case and a wrapper for the COMPAT_ISA case (of the cy driver). This cleans up new-busification of the pci case but takes the COMPAT_ISA case a little further from new-bus. The corresponding bug for the COMPAT_ISA case has already been fixed similarly using a wrapper in compat_isa.c and we need another wrapper just to undo that. Fixed some directly related style bugs (mainly by removing compatibility cruft). cy.c: Fixed an indirectly related old bug in cyattach_common(). A wrong status was returned in the unlikely event that malloc() failed. Approved by: re (scottl)
* Restored the call to schedsofttty() (now spelled swi_sched(...)) again.bde2003-11-162-28/+38
| | | | | | | | Its restoration in rev.1.102 was mistranslated to the equivalent of setsofttty() in rev.1.105. This increased overheads by causing a context switch to the SWI handler after almost every interrupt. The increase was approx. 50% on a Celeron 366 (from 23 usec to 34 usec per interrupt).

* MFsio (sio.c 1.413: cleaned up and fixed setting of speeds in comparam()).bde2003-09-272-46/+24
| | | | | | This is just a cleanup here (modulo rev.1.108 of kern/tty.c), since the input speed can be different from to output speed and extra code to handle both speeds naturally handled all cases.
* Quick fix for bitrot in locking in the SMP case. cd_getreg() andbde2003-09-272-8/+48
| | | | | | | | | | cd_setreg() were still using !(read_eflags() & PSL_I) as the condition for the lock hidden by COM_LOCK() (if any) being held. This worked when spin mutexes and/or critical_enter() used hard interrupt disablement, but it has caused recursion on the non-recursive mutex com_mtx since all relevant interrupt disablement became soft. The recursion is harmless unless there are other bugs, but it breaks an invariant so it is fatal if spinlocks are witnessed.

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. Approved by: re(scottl)

* Change the suser() API to take advantage of td_ucred as well as do ajhb2002-04-012-6/+6
| | | | | | | | | | | | 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.
