* Convert all users of fldoff() to offsetof(). fldoff() is badphk2000-10-271-2/+0
| | | | | | | | | | | | | | | | | | | | | | | because it only takes a struct tag which makes it impossible to use unions, typedefs etc. Define __offsetof() in <machine/ansi.h> Define offsetof() in terms of __offsetof() in <stddef.h> and <sys/types.h> Remove myriad of local offsetof() definitions. Remove includes of <stddef.h> in kernel code. NB: Kernelcode should *never* include from /usr/include ! Make <sys/queue.h> include <machine/ansi.h> to avoid polluting the API. Deprecate <struct.h> with a warning. The warning turns into an error on 01-12-2000 and the file gets removed entirely on 01-01-2001. Paritials reviews by: various. Significant brucifications by: bde

| | | | | | | | | | | | | | | <sys/bio.h>. <sys/bio.h> is now a prerequisite for <sys/buf.h> but it shall not be made a nested include according to bdes teachings on the subject of nested includes. Diskdrivers and similar stuff below specfs::strategy() should no longer need to include <sys/buf.> unless they need caching of data. Still a few bogus uses of struct buf to track down.

* Pre 4.0 tidy up.peter2000-01-141-1/+1
| | | | | | | | | | | | Collect together the components of several drivers and export eisa from the i386-only area (It's not, it's on some alphas too). The code hasn't been updated to work on the Alpha yet, but that can come later. Repository copies were done a while ago. Moving these now keeps them in consistant place across the 4.x series as the newbusification progresses. Submitted by: mdodd

* Convert DEVFS hooks in (most) drivers to make_dev().phk1999-08-232-11/+2

Vinum, i4b, alpha, pc98 not dealt with (left to respective Maintainers) Add the correct hook for devfs to kern_conf.c The net result of this excercise is that a lot less files depends on DEVFS, and devtoname() gets more sensible output in many cases. A few drivers had minor additional cleanups performed relating to cdevsw registration. A few drivers don't register a cdevsw{} anymore, but only use make_dev().

* Move the specification of EDGE/LEVEL triggered interrupts tomdodd1999-08-012-12/+14
| | | | | | | | | | | | | | | | | eisa_add_intr() which now takes an additional arguement (one of EISA_TRIGGER_LEVEL or EISA_TRIGGER_EDGE). The flag RR_SHAREABLE has no effect when passed to bus_alloc_resource(dev, SYS_RES_IRQ, ...) in an EISA device context as the eisa_alloc_resource() call (bus_alloc_resource method) now deals with this flag directly, depending on the device ivars. This change does nothing more than move all the 'shared = inb(foo + iobsse)' nonesense to the device probe methods rather than the device attach. Also, print out 'edge' or 'level' in the IRQ announcement message. Reviewed by: dfr
* Simplify cdevsw registration.phk1999-05-311-7/+2
| | | | | | | | | | | | | | | | | | | | | | | | | The cdevsw_add() function now finds the major number(s) in the struct cdevsw passed to it. cdevsw_add_generic() is no longer needed, cdevsw_add() does the same thing. cdevsw_add() will print an message if the d_maj field looks bogus. Remove nblkdev and nchrdev variables. Most places they were used bogusly. Instead check a dev_t for validity by seeing if devsw() or bdevsw() returns NULL. Move bdevsw() and devsw() functions to kern/kern_conf.c Bump __FreeBSD_version to 400006 This commit removes: 72 bogus makedev() calls 26 bogus SYSINIT functions if_xe.c bogusly accessed cdevsw[], author/maintainer please fix.

| | | | | | | | | | | | | Reformat and initialize correctly all "struct cdevsw". Initialize the d_maj and d_bmaj fields. The d_reset field was not removed, although it is never used. I used a program to do most of this, so all the files now use the same consistent format. Please keep it that way. Vinum and i4b not modified, patches emailed to respective authors.

| | | | | | | | | | | | | bad math: it does not handle page-boundary conditions, and will not end up mapping all of the requested addresses. This will cause a panic: page fault during probe on some systems. I have a machine that will panic every time (when using the dpt driver) on kernel probe when there are 5 drives installed. When there are 4 drives, it is fine. Fix is to always allocate/deallocate an extra page. There is also a bonus splx() fix on an early error return. Submitted by: Mark J.

(The reason for this is that I'm trying to progressively eliminate use of linker_sets where it hurts modularity and runtime load capability, and these DATA_SET's keep getting in the way.)

A make world is recommended. camcontrol.[c8]: - We now support two new commands, "tags" and "negotiate". - The tags commands allows users to view the number of tagged openings for a device as well as a number of other related parameters, and it allows users to set tagged openings for a device. - The negotiate command allows users to enable and disable disconnection and tagged queueing, set sync rates, offsets and bus width. Note that not all of those features are available for all controllers. Only the adv, ahc, and ncr drivers fully support all of the features at this point. Some cards do not allow the setting of sync rates, offsets and the like, and some of the drivers don't have any facilities to do so. Some drivers, like the adw driver, only support enabling or disabling sync negotiation, but do not support setting sync rates. - new description in the camcontrol man page of how to format a disk - cleanup of the camcontrol inquiry command - add support in the 'devlist' command for skipping unconfigured devices if -v was not specified on the command line. - make use of the new base_transfer_speed in the path inquiry CCB. - fix CCB bzero cases cam_xpt.c, cam_sim.[ch], cam_ccb.h: - new flags on many CCB function codes to designate whether they're non-immediate, use a user-supplied CCB, and can only be passed from userland programs via the xpt device. Use these flags in the transport layer and pass driver to categorize CCBs. - new flag in the transport layer device matching code for device nodes that indicates whether a device is unconfigured - bump the CAM version from 0x10 to 0x11 - Change the CAM ioctls to use the version as their group code, so we can force users to recompile code even when the CCB size doesn't change. - add + fill in a new value in the path inquiry CCB, base_transfer_speed. Remove a corresponding field from the cam_sim structure, and add code to every SIM to set this field to the proper value. - Fix the set transfer settings code in the transport layer. scsi_cd.c: - make some variables volatile instead of just casting them in various places - fix a race condition in the changer code - attach unless we get a "logical unit not supported" error. This should fix all of the cases where people have devices that return weird errors when they don't have media in the drive. scsi_da.c: - attach unless we get a "logical unit not supported" error scsi_pass.c: - for immediate CCBs, just malloc a CCB to send the user request in. This gets rid of the 'held' count problem in camcontrol tags. scsi_pass.h: - change the CAM ioctls to use the CAM version as their group code. adv driver: - Allow changing the sync rate and offset separately. adw driver - Allow changing the sync rate and offset separately. aha driver: - Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs. ahc driver: - Allow setting offset and sync rate separately bt driver: - Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs. NCR driver: - Fix the ultra/ultra 2 negotiation bug - allow setting both the sync rate and offset separately Other HBA drivers: - Put code in to set the base_transfer_speed field for XPT_GET_TRAN_SETTINGS CCBs.
