* Switch the vm_object mutex to be a rwlock. This will enable in theAttilio Rao2013-03-092-13/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | future further optimizations where the vm_object lock will be held in read mode most of the time the page cache resident pool of pages are accessed for reading purposes. The change is mostly mechanical but few notes are reported: * The KPI changes as follow: - VM_OBJECT_LOCK() -> VM_OBJECT_WLOCK() - VM_OBJECT_TRYLOCK() -> VM_OBJECT_TRYWLOCK() - VM_OBJECT_UNLOCK() -> VM_OBJECT_WUNLOCK() - VM_OBJECT_LOCK_ASSERT(MA_OWNED) -> VM_OBJECT_ASSERT_WLOCKED() (in order to avoid visibility of implementation details) - The read-mode operations are added: VM_OBJECT_RLOCK(), VM_OBJECT_TRYRLOCK(), VM_OBJECT_RUNLOCK(), VM_OBJECT_ASSERT_RLOCKED(), VM_OBJECT_ASSERT_LOCKED() * The vm/vm_pager.h namespace pollution avoidance (forcing requiring sys/mutex.h in consumers directly to cater its inlining functions using VM_OBJECT_LOCK()) imposes that all the vm/vm_pager.h consumers now must include also sys/rwlock.h. * zfs requires a quite convoluted fix to include FreeBSD rwlocks into the compat layer because the name clash between FreeBSD and solaris versions must be avoided. At this purpose zfs redefines the vm_object locking functions directly, isolating the FreeBSD components in specific compat stubs. The KPI results heavilly broken by this commit. Thirdy part ports must be updated accordingly (I can think off-hand of VirtualBox, for example).

* agp.c:Marcel Moolenaar2012-07-062-4/+2
| | | | | | | | | | | | | | | | | | | | | | Don't use Maxmem when the amount of memory is meant. Use realmem instead. Maxmem is not only a MD variable, it represents the highest physical memory address in use. On systems where memory is sparsely layed-out the highest memory address and the amount of memory are not interchangeable. Scaling the AGP aperture based on the actual amount of memory (= realmem) rather than the available memory (= physmem) makes sure there's consistent behaviour across architectures. agp_i810.c: While arguably the use of Maxmem can be considered correct, replace its use with realmem anyway. agp_i810.c is specific to amd64, i386 & pc98, which have a dense physical memory layout. Avoiding Maxmem here is done with an eye on copy-n-paste behaviour in general and to avoid confusion caused by using realmem in agp.c and Maxmem in agp_i810.c. In both cases, remove the inclusion of md_var.h Notes: svn path=/head/; revision=238172

* Replace all calls to minor() with dev2unit().Ed Schouten2008-09-271-1/+1
| | | | | | | | | | | | | | | | | | After I removed all the unit2minor()/minor2unit() calls from the kernel yesterday, I realised calling minor() everywhere is quite confusing. Character devices now only have the ability to store a unit number, not a minor number. Remove the confusion by using dev2unit() everywhere. This commit could also be considered as a bug fix. A lot of drivers call minor(), while they should actually be calling dev2unit(). In -CURRENT this isn't a problem, but it turns out we never had any problem reports related to that issue in the past.

Apertures of 32MB and 64MB only use a 16 page GATT and an aperture of 128MB only uses a 32 page GATT, so without this the code could walk off the end of the pointer and cause a page fault if the next page was unmapped. Also, for aperture sizes > 128MB, not all of the pages would be read. The Linux driver has the same bug.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a function to agp.c to set the aperture resource ID if it's not the usual AGP_APBASE. Previously, agp.c had been assuming AGP_APBASE, which resulted in incorrect agp_info, and contortions by agp_i810.c to work around it. This also adds functions to agp.c for default AGP_GET_APERTURE() and AGP_SET_APERTURE(), which return the aperture resource size and disallow aperture size changes. Moving to these for our AGP drivers will likely result in stability improvements. This should fix 855-class aperture size detection. Additionally, refuse to attach agp_i810 when some RAM is above 4GB and the GART can't reference memory that high. This should be very rare. The correct solution would be bus_dma conversion for agp, which is beyond the scope of this change. Other AGP drivers could likely use this change as well. G33/Q35/Q33 AGP support is also included, but disconnected by default due to lack of testing.
