Sat, 15 Sep 2001 20:36:31 +0000

a whole bunch of changes to improve performance and robustness under load: - remove special treatment of pager_map mappings in pmaps. this is required now, since I've removed the globals that expose the address range. pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's no longer any need to special-case it. - eliminate struct uvm_vnode by moving its fields into struct vnode. - rewrite the pageout path. the pager is now responsible for handling the high-level requests instead of only getting control after a bunch of work has already been done on its behalf. this will allow us to UBCify LFS, which needs tighter control over its pages than other filesystems do. writing a page to disk no longer requires making it read-only, which allows us to write wired pages without causing all kinds of havoc. - use a new PG_PAGEOUT flag to indicate that a page should be freed on behalf of the pagedaemon when it's unlocked. this flag is very similar to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the pageout fails due to eg. an indirect-block buffer being locked. this allows us to remove the "version" field from struct vm_page, and together with shrinking "loan_count" from 32 bits to 16, struct vm_page is now 4 bytes smaller. - no longer use PG_RELEASED for swap-backed pages. if the page is busy because it's being paged out, we can't release the swap slot to be reallocated until that write is complete, but unlike with vnodes we don't keep a count of in-progress writes so there's no good way to know when the write is done. instead, when we need to free a busy swap-backed page, just sleep until we can get it busy ourselves. - implement a fast-path for extending writes which allows us to avoid zeroing new pages. this substantially reduces cpu usage. - encapsulate the data used by the genfs code in a struct genfs_node, which must be the first element of the filesystem-specific vnode data for filesystems which use genfs_{get,put}pages(). - eliminate many of the UVM pagerops, since they aren't needed anymore now that the pager "put" operation is a higher-level operation. - enhance the genfs code to allow NFS to use the genfs_{get,put}pages instead of a modified copy. - clean up struct vnode by removing all the fields that used to be used by the vfs_cluster.c code (which we don't use anymore with UBC). - remove kmem_object and mb_object since they were useless. instead of allocating pages to these objects, we now just allocate pages with no object. such pages are mapped in the kernel until they are freed, so we can use the mapping to find the page to free it. this allows us to remove splvm() protection in several places.The sum of all these changes improves write throughput on mydecstation 5000/200 to within 1% of the rate of NetBSD 1.5and reduces the elapsed time for "make release" of a NetBSD 1.5source tree on my 128MB pc to 10% less than a 1.5 kernel took.

651b44e2111eb94a39464a8a74e0c3cde85ac20b - Rework the way kernel include files are installed. In the new method,

Fri, 12 Jun 1998 23:22:30 +0000

Rework the way kernel include files are installed. In the new method,as with user-land programs, include files are installed by each directoryin the tree that has includes to install. (This allows more flexibilityas to what gets installed, makes 'partial installs' easier, and gives usmore options as to which machines' includes get installed at any giventime.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_still supported, though at least one bug in the 'symlinks' case isfixed by this change. Include files can't be build before installation,so directories that have includes as targets (e.g. dev/pci) have to movethose targets into a different Makefile.
