* | | Set a "kernbase" symbol in 32-bit arm locore.S and use it with ldscript.arm.Ian Lepore2019-12-303-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This brings arm into line with how every other arch does it. For some reason, only arm lacked a definition of a symbol named kernbase in its locore.S file(s) for use in its ldscript.arm file. Needlessly different means harder to maintain.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In IRC, sfs_ finally managed to get a good trace of a kernel panic that was happening when attempting to use webengine. As it turns out, we were using vtophys() from interrupt context on an idle thread in opal_hmi_handler2(). Since this involves locking the kernel pmap on PPC64 at the moment, this ended up tripping a KASSERT in mtx_lock(), which then caused a parallel panic stampede. So, avoid this by preallocating the flags variable and storing it in PCPU. Fixes "panic: mtx_lock() by idle thread 0x... on sleep mutex kernelpmap".

This change converts the source_list LIST to a ConcurrencyKit CK_LIST and uses an epoch(9) to protect typical read accesses of the list. The existing HARVEST_LOCK spin mutex is used to safely add and remove list entries. random_source_deregister() uses epoch_wait() to ensure no concurrent source_list readers are accessing a random_source before freeing the list item and returning to the caller. Callers can safely unload immediately after random_source_deregister() returns.

But from one side it did not close all the races, while from another was quite expensive on SMP due to trashing twice per request cache lines of consumer and provider and requiring locks. It lost its sense after I manually went through all the GEOM classes in base and made orphanization wait for either provider close or request completion. Consumer counters are still used under INVARIANTS to detect premature consumer close and detach. Provider counters are removed completely. Sponsored by: iXsystems, Inc.

Plus, as number of people commented, GEOM is not the best place for I/O scheduler, since it has limited information about layers both above and below it, required for efficient scheduling. Plus with the modern shift to SSDs there is just no more significant need for this kind of scheduling. Approved by: imp, phk, luigi Relnotes: yes Notes: svn path=/head/; revision=356185

The main thrust of this change is to generate a kernel that has the arm "marker" symbols stripped. Marker symbols start with $a, $d, $t or $x, and are emitted by the compiler to tell other toolchain components about the locations of data embedded in the instruction stream (literal-pool stuff). They are used for generating mixed-endian binaries (which we don't support). The linked kernel has approximately 21,000 such symbols in it, wasting space (500K in kernel.full, 190K in the final linked kernel), and sometimes obscuring function names in stack tracebacks. This change also simplifies the way the kernel is linked. Instead of using sed to generate two different ldscript files to generate both an elf kernel and a binary (elf headers stripped) kernel, we now use a single ldscript that refers to a "text_start" symbol, and we provide the value for that symbol using --defsym on the linker command line.

The original patch introduced the new flag, which sets the fail/rate to 100% after N requests. In some cases, we don't want to have 100% of failure probabilities. We want to start failing at some point. For example, on the early stage, we may like to allow some read/writes requests before having some requests delayed - when we try to mount the partition, or when we are trying to import the pool. Another case may be to check how scrub in ZFS will behave on different stages. This allows us to cover more cases. The previous behavior still may be configured.
