* iflib: Drop tx lock when freeing mbufs using simple_transmitAndrew Gallatin2 days1-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Freeing completed transmit mbufs can be time consuming (due to them being cold in cache, and due to ext free routines taking locks), especially when we batch tx completions. If we do this when holding the tx ring mutex, this can cause lock contention on the tx ring mutex when using iflib_simple_transmit. To resolve this, this patch opportunistically copies completed mbuf pointers into a new array (ifsd_m_defer) so they can be freed after dropping the transmit mutex. The ifsd_m_defer array is opportunistically used, and may be NULL. If its NULL, then we free mbufs in the old way. The ifsd_m_defer array is atomically nulled when a thread is using it, and atomically restored when the freeing thread is done with it. The use of atomics here avoids acquire/release of the tx lock to restore the array after freeing mbufs. Since we're no longer always freeing mbufs inline, peeking into them to see if a transmit used TSO or not will cause a useless cache miss, as nothing else in the mbuf is likely to be accessed soon. To avoid that cache miss, we encode a TSO or not TSO flag in the lower bits of the mbuf pointer stored in the ifsd_m array. Note that the IFLIB_NO_TSO flag exists primarily for sanity/debugging. iflib_completed_tx_reclaim() was refactored to break out iflib_txq_can_reclaim() and _iflib_completed_tx_reclaim() so the that the tx routine can call iflib_tx_credits_update() just once, rather than twice. Note that deferred mbuf freeing is not enabled by default, and can be enabled using the dev.$DEV.$UNIT.iflib.tx_defer_mfree sysctl.

* kernel: MK_REPRODUCIBLE_PATHS for full paths vs /usr/srcWarner Losh13 days1-1/+8
| | | | | | | | | | | | | | | | | | | | | | There are many environments that you do not want the paths to be canonicalized. For example, if I always build a product from a specific path in a jail that's dependent on the product version, I don't want that to be sanitized to /usr/src because when I have profiling tools run against multiple kernels, I can't do A/B testing and results processing if everything points to /usr/src (sadly, the profiling tools cannot remap back to the original like gdb can). Since we need both active at the same time, symbloic link fallbacks don't work. We do want the rest of the build to be reproducible, however. We'll get the same binaries if we rebuild later since we always rebuild with the same path. Turn them both on for maximum reproduction for environments where that cannot be guaranteed.

| | | | | | | | | | | | | | | | | | | | | In commit 2e47f35be5dc libllvm, libclang and liblldb were converted into private shared libraries. This allowed clang, lld, lldb, and other llvm tools to be linked against these shared libraries, which makes them smaller and avoids duplication. However, this also comes at the cost of some performance, since the dynamic libraries are quite large, and contain lots of long symbols (mangled C++ identifiers). Add a WITH_LLVM_LINK_STATIC_LIBRARIES build knob that can be used to go back to the previous behavior: libllvm, libclang and liblldb are built as internal static libraries, i.e. only available during buildworld, and fully linked into the various executables such as clang, lld, etc. PR: 287447 Reviewed by: emaste MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D50956

* cam: Reduce overly long timeout values for initial device probingWarner Losh2025-12-111-1/+33
| | | | | | | | | | | | | | | | | | | | | | | Currently, we have very long timeouts for the initial probing commands. However, these are not appropriate for modern (post 2010) SCSI disks. Sandards since SPC3 state that these commands should not wait for media access. Since we retry them several times during the initial bus scan, these delays can delay the boot by minutes (5 minutes per errant disk in our expereince). These delays don't help and only hurt, so reduce the TESTUNITREADY, INQUIRY and MODESENSE commands (during the initial probe). Provide sysctl/tuneables to change the time for these and also the REPORTLUNS commands for people that might need to adjust them for devices that violate this belief but none-the-less work with longer timeouts. kern.cam.tur_timeout (default was 60s, now 1s) kern.cam.inquiry_timeout (default was 60s, now 1s) kern.cam.reportluns_timeout (default is 60s) kern.cam.modesense_timeout (default was 60s, now 1s) This can be partially merged: the sysctls can, but the new defaults likely shouldn't.
