Improve I/O functions to match Linux: - Reverse byte order on big-endian architectures (except on sparc64) - Add memory barriers Note that sparc64 is special as we use a little-endian mapping for PCI bus space, so we shouldn't reverse the byte order there. ok jsg@ |

kevent(2): ktrace the timeout before validating it As deraadt@ has pointed out, tracing timevals and timespecs before validating them makes debugging easier. |

Switch the pmap and PDP pools to IPL_VM, drop the PR_WAITOK flag from the PDP pool and use the single page allocator for the PDP pool. This makes pmap_destroy(9) mpsafe while preventing additional pressure on the interrupt-safe kernel map. ok mpi@ |

| message |
Fix a deadlock between uvn_io() and uvn_flush(). While faulting on a page backed by a vnode, uvn_io() will end up being called in order to populate newly allocated pages using I/O on the backing vnode. Before performing the I/O, newly allocated pages are flagged as busy by uvn_get(), that is before uvn_io() tries to lock the vnode. Such pages could then end up being flushed by uvn_flush() which already has acquired the vnode lock. Since such pages are flagged as busy, uvn_flush() will wait for them to be flagged as not busy. This will never happens as uvn_io() cannot make progress until the vnode lock is released. Instead, grab the vnode lock before allocating and flagging pages as busy in uvn_get(). This does extend the scope in uvn_get() in which the vnode is locked but resolves the deadlock. ok mpi@ Reported-by: [email protected] |

Make mapping the "I/O Space" BAR optional. POWER9 systems don't support "I/O Space" on their PCIe host bridges and for most (all) Radeon variants there is an alternative method to access the relevant registers. ok jsg@ |

| message |
Retguard asm macros for powerpc libc, ld.so Add retguard to some, but not all, asm functions in libc. Edit SYS.h in libc to remove the PREFIX macros and add SYSENTRY (more like aarch64 and powerpc64), so we can insert RETGUARD_SETUP after SYSENTRY. Some .S files in this commit don't get retguard, but do stop using the old prefix macros. Tested by deraadt@, who put this diff in a macppc snap. |
