r358262	imp	Feb. 23, 2020, 7:04 p.m.	Use MACHINE_ARCH instead of TARGET_ARCH TARGET_ARCH is only for use in Makefile.inc1 contexts. MACHINE_ARCH is the preferred thing to set. Makefile.inc1 sets MACHINE_ARCH in the cross build case, and make sets it in the native build case. This will fix anybody doing a native build. Add a comment for why we have to do this dance so when/if the problem with CFLAGS is fixed for the kernel this workaround can be removed. ViewVC
r358261	markj	Feb. 23, 2020, 5:59 p.m.	Allow swap_pager_putpages() to allocate one block at a time. The minimum allocation size of 4 blocks is an old policy that came with the "new" swap pager in r42957. Since then the blist allocator has gotten better at reducing fragmentation; for example, with r349777 it can return a range that spans multiple leaves. When swap space is close to being exhaused, the minimum of 4 blocks most likely exacerbates memory pressure, so reduce it to 1.

r358252	kib	Feb. 22, 2020, 8:50 p.m.	Fix NFS client deadlock when read reports truncated node. If node attribute returned in the reply for read rpc indicate truncation, and it happens that the vnode is exclusively locked, update of the node attributes would try to shrink vnode size. Since during the read some vnode pages were busied by the reading thread, vnode_pager_setsize() deadlocks waiting for the busy state owned by the caller. Use a thread-local flag to indicate that NFS read owns some (s)busy pages states and postpone the call to vnode_pager_setsize() until the thread relinguishes the ownership.

r358247	kp	Feb. 22, 2020, 1:23 p.m.	riscv: Set MACHINE_ARCH correctly MACHINE_ARCH sets the hw.machine_arch sysctl in the kernel. In userspace it sets MACHINE_ARCH in bmake, which bsd.cpu.mk uses to configure the target ABI for ports. For riscv64sf builds (i.e. soft-float) that needs to be riscv64sf, but the sysctl didn't reflect that. It is static. Set the define from the riscv makefile so that we correctly reflect our actual build (i.e. riscv64 or riscv64sf), depending on what TARGET_ARCH we were built with. That still doesn't satisfy userspace builds (e.g. bmake), so check if we're building with a software-floating point toolchain there. That check doesn't work in the kernel, because it never uses floating point.

r358236	jeff	Feb. 22, 2020, 3:44 a.m.	Add an atomic-free tick moderated lazy update variant of SMR. This enables very cheap read sections with free-to-use latencies and memory overhead similar to epoch. On a recent AMD platform a read section cost 1ns vs 5ns for the default SMR. On Xeon the numbers should be more like 1 ns vs 11. The memory consumption should be proportional to the product of the free rate and 2*1/hz while normal SMR consumption is proportional to the product of free rate and maximum read section time. While here refactor the code to make future additions more straightforward. Name the overall technique Global Unbound Sequences (GUS) and adjust some comments accordingly. This helps distinguish discussions of the general technique (SMR) vs this specific implementation (GUS). Discussed with: rlibby, markj ViewVC
