Use uintptr_t instead of unsigned long for pointers.

2020-12-16T00:13:32Z

The sense_ptr thing is quite broken. As near as I can tell, the driver tries to copyout to a physical address rather than whatever user address the sense buffer should be copied to. It is not immediately obvious what user address the sense buffer should be copied to.

Make MAXPHYS tunable. Bump MAXPHYS to 1M.

2020-11-28T12:12:51Z

Replace MAXPHYS by runtime variable maxphys. It is initialized from MAXPHYS by default, but can be also adjusted with the tunable kern.maxphys. Make b_pages[] array in struct buf flexible. Size b_pages[] for buffer cache buffers exactly to atop(maxbcachebuf) (currently it is sized to atop(MAXPHYS)), and b_pages[] for pbufs is sized to atop(maxphys) + 1. The +1 for pbufs allow several pbuf consumers, among them vmapbuf(), to use unaligned buffers still sized to maxphys, esp. when such buffers come from userspace (*). Overall, we save significant amount of otherwise wasted memory in b_pages[] for buffer cache buffers, while bumping MAXPHYS to desired high value. Eliminate all direct uses of the MAXPHYS constant in kernel and driver sources, except a place which initialize maxphys. Some random (and arguably weird) uses of MAXPHYS, e.g. in linuxolator, are converted straight. Some drivers, which use MAXPHYS to size embeded structures, get private MAXPHYS-like constant; their convertion is out of scope for this work.

mrsas: clean up empty lines in .c and .h files

Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (17 of many)

2020-02-26T14:26:36Z

r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are still not MPSAFE (or already are but aren’t properly marked). Use it in preparation for a general review of all nodes. This is non-functional change that adds annotations to SYSCTL_NODE and SYSCTL_PROC nodes using one of the soon-to-be-required flags. Mark all obvious cases as MPSAFE. All entries that haven't been marked as MPSAFE before are by default marked as NEEDGIANT Approved by: kib (mentor, blanket) Commented by: kib, gallatin, melifaro Differential Revision: https://reviews.freebsd.org/D23718

Fix some misleading indentation warnings reported by recent clang.

2020-01-26T14:20:57Z

These should not be any functional change. While the change in emul10kx-pcm.c looks like a real bug fix (as opposed to inconsistent whitespace), the extra statements were not harmful. Reviewed by: kib Sponsored by: DARPA Differential Revision: https://reviews.freebsd.org/D23363

add mrsas_shutdown method

2019-05-23T12:51:13Z

It should be safer to flush controller and disk caches on the shutdown. And to gracefully shut down the controller as well. It seems that the Linux driver has been doing that for a long time.

Extract eventfilter declarations to sys/_eventfilter.h

2019-05-20T00:38:23Z

This allows replacing "sys/eventfilter.h" includes with "sys/_eventfilter.h" in other header files (e.g., sys/{bus,conf,cpu}.h) and reduces header pollution substantially. EVENTHANDLER_DECLARE and EVENTHANDLER_LIST_DECLAREs were moved out of .c files into appropriate headers (e.g., sys/proc.h, powernv/opal.h). As a side effect of reduced header pollution, many .c files and headers no longer contain needed definitions. The remainder of the patch addresses adding appropriate includes to fix those files. LOCK_DEBUG and LOCK_FILE_LINE_ARG are moved to sys/_lock.h, as required by sys/mutex.h since r326106 (but silently protected by header pollution prior to this change). No functional change (intended). Of course, any out of tree modules that relied on header pollution for sys/eventhandler.h, sys/lock.h, or sys/mutex.h inclusion need to be fixed. __FreeBSD_version has been bumped.
