* Centralize the devstat handling for all GEOM disk device driversPoul-Henning Kamp2003-03-081-1/+0
| | | | | | | | | | | in geom_disk.c. As a side effect this makes a lot of #include <sys/devicestat.h> lines not needed and some biofinish() calls can be reduced to biodone() again. Notes: svn path=/head/; revision=111979

| | | | | | | | | | | | | | | | 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.

Add some new commands states; WEDGED (never coming back) and LATE (for when a command that wasmarked as WEDGED comes bacj, - Remove a number of redundant efforts to poll the card for completed commands. This is what interrupt handlers are for. - Limit the maximum number of outstanding I/O transactions. It seems that some controllers report more than they can really handle, and exceding this limit can cause the controller to lock up. - Don't use 'wait' mode for anything where the controller might not be able to generate interrupts. (Keep the 'wait' mode though sa it will become useful when we start taking userspace commands. - Use a similar atomic locking trategy to the Mylex driver to prevent some reentrancy problems. - Correctly calculate the block count for non-whoile-bloch transfers (actually illegal). - Use the dsik device's si_drv1 field instead of b_driver1 in the buf struct to pass the driver identifier arond. - Rewrite amr_start and amr_done() along the lines of the Mylex driver in order to improve robustnes. - Always force the PCI busmaster bit on.

| | | | | | | | | | | | | | | | | | | | | | | | field in struct buf: b_iocmd. The b_iocmd is enforced to have exactly one bit set. B_WRITE was bogusly defined as zero giving rise to obvious coding mistakes. Also eliminate the redundant struct buf flag B_CALL, it can just as efficiently be done by comparing b_iodone to NULL. Should you get a panic or drop into the debugger, complaining about "b_iocmd", don't continue. It is likely to write on your disk where it should have been reading. This change is a step in the direction towards a stackable BIO capability. A lot of this patch were machine generated (Thanks to style(9) compliance!)
