* Attempt to approximate what should happen on a suspend/resume cycle.deraadt2013-12-281-1/+12
| | | | | | | | If the driver was doing some IO, we remove the timeouts, and force the fdc state machine into IOTIMEDOUT state with the final timeout count before a clean retry. In theory upon resume it should freak out quietly, and try the operation again. Noone has stepped forward to test this yet.
* remove the #define b_cylinder b_resid from bufs. i hated thedlg2013-11-211-12/+17
| | | | | | | | | | | | | | | | | | | overloading of that thing. the only hardware that seems to care about cylinders in our tree are floppy drives, and the drivers for those calculate their own cylinders from logical block addresses and ignore whatever the rest of the kernel thought b_cylinders should be. most of this diff is moving the floppy drivers to using b_resid as a resid and using that as part of the calculation for real cylinder values. the rest of the diff is getting rid of the useless assignments to b_cylinder that dont get used by anything (now that disksort is gone). ok miod@

* Don't pass uninitialized stack memory to setdisklabel() as the 'old'krw2009-09-061-4/+5
| | | | | | | | label. Use the existing label, since we now check and reuse some values in it. And that's what all other drivers do. Bonus: we don't need that label on the stack anymore. ok deraadt@

* Replace the error strings that were being passed around with much simplerderaadt2009-08-131-9/+4
| | | | | | | | | errnos. Note that the error strings are being ignored, since we long ago decided to not spam the console, and there is no other nice way to use the errors (without changing the ioctls to pass it back) The errno is now useful, since we can pass b_error from failing IO up, and the drive can decide how to use that ok miod

* Second pass of simple timeout_add -> timeout_add_sec conversionsblambert2008-10-151-5/+5
| | | | | | | This should take care of the simpler ones (i.e., timeout values of integer multiples of hz). ok krw@, art@

* back out biomem diff since it is not right yet. Doing very largederaadt2008-06-111-2/+2
| | | | | | | | file copies to nfsv2 causes the system to eventually peg the console. On the console ^T indicates that the load is increasing rapidly, ddb indicates many calls to getbuf, there is some very slow nfs traffic making none (or extremely slow) progress. Eventually some machines seize up entirely.
* Fix buffer cache pending read statistics by ensuring we can identifybeck2008-06-101-2/+2
| | | | | | | | biowait() reads that do *not* come from the buffer cache - we use the B_RAW flag to identify these at art's suggestion - since it makes sense and the flag was not being used. this just flags all these buffers with B_RAW - biodone already ignores returned buffers marked B_RAW. ok art@

* now that all partition size/offsets are potentially 64-bit, change thederaadt2007-06-061-4/+4
| | | | | | | type of all variables to daddr64_t. this includes the APIs for XXsize() and XXdump(), all range checks inside bio drivers, internal variables for disklabel handling, and even uvm's swap offsets. re-read numerous times by otto, miod, krw, thib to look for errors

* 2nd one found: If you really wish to make a function __inline (which willderaadt2007-05-081-3/+3
| | | | | | be called once), please also make it static so that the compiler does not generate a 2nd one to export to outside callers! that is a stupid waste of space.

* Don't print the error strings returned by readdisklabel(). If youkrw2007-02-151-2/+2
| | | | | | | | | need the debug info uncomment the printf's you need. Crude but effective way to suppress 'no disklabel' errors that pop up at the most innconvenient times to frighten users. More elegant method, DPRINTF-like constructs or something, later. "Yay!" marco@ ok deraadt@

* Kernel stack can be swapped. This means that stuff that's on the stackmiod2006-11-291-3/+1
| | | | | | | | | | should never be referenced outside the context of the process to which this stack belongs unless we do the PHOLD/PRELE dance. Loads of code doesn't follow the rules here. Instead of trying to track down all offenders and fix this hairy situation, it makes much more sense to not swap kernel stacks. From art@, tested by many some time ago.
* Zap D_REMOVABLE flag from disklabel. If you didn't already know thatkrw2006-09-261-2/+1
| | | | | | | | floppies and cd's were removable, displaying that fact in disklabel output was unlikely to help. And the display in disklabel was the only use of D_REMOVABLE in the tree. ok marco@
* RAW_PART p_size on floppies and mcd's should be in sectors.krw2006-08-131-3/+2
| | | | | | | | | Only 'Japanese 1.2MB' floppies have sectors that are not 512 bytes, according to isa/fd.c's fd_types[]. SCSI/ATAPI cd's already use sectors, and mcd cd's should be no different. So there should be no functional change.
* Define and use FD_BSIZE, similar to FD_BSIZE from sparc and sparc64krw2006-08-131-9/+7
| | | | | | | fd. Eliminate unused variable and FDC_BSIZE which was only used to set value of the unused variable. No change to object file.
