| * | plugins: fix memory leak while parsing options | Alex Bennée | 2023-07-03 | 1 | -1/+1 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was hard to track down this leak as it was an internal allocation by glib and the backtraces did not give much away. The autofree was freeing the allocation with g_free() but not taking care of the individual strings. They should have been freed with g_strfreev() instead. Searching the glib source code for the correct string free function led to: G_DEFINE_AUTO_CLEANUP_FREE_FUNC(GStrv, g_strfreev, NULL) and indeed if you read to the bottom of the documentation page you will find: typedef gchar** GStrv; A typedef alias for gchar**. This is mostly useful when used together with g_auto(). So fix up all the g_autofree g_strsplit case that smugly thought they had de-allocation covered.

| * | tests/plugin: Remove duplicate insn log from libinsn.so | Richard Henderson | 2023-06-26 | 1 | -8/+1 |
| | | | | | | | | | | | | | This is a perfectly natural occurrence for x86 "rep movb", where the "rep" prefix forms a counted loop of the one insn. During the tests/tcg/multiarch/memory test, this logging is triggered over 350000 times. Within the context of cross-i386-tci build, which is already slow by nature, the logging is sufficient to push the test into timeout.

| * | tests/plugins: add instruction matching to libinsn.so | Alex Bennée | 2022-02-09 | 1 | -1/+88 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds simple instruction matching to the libinsn.so plugin which is useful for examining the execution distance between instructions. For example to track how often we flush in ARM due to TLB updates: -plugin ./tests/plugin/libinsn.so,match=tlbi which leads to output like this: 0xffffffc01019a918, 'tlbi vale1is, x1', 5702 hits, 31825 match hits, Δ+8112 since last match, 68859 avg insns/match 0xffffffc01019a918, 'tlbi vale1is, x1', 5703 hits, 56593 match hits, Δ+17712125 since last match, 33455 avg insns/match 0xffffffc01019a918, 'tlbi vale1is, x1', 5704 hits, 56594 match hits, Δ+12689 since last match, 33454 avg insns/match 0xffffffc01019a918, 'tlbi vale1is, x1', 5705 hits, 56595 match hits, Δ+12585 since last match, 33454 avg insns/match 0xffffffc01019a918, 'tlbi vale1is, x1', 5706 hits, 56596 match hits, Δ+10491 since last match, 33454 avg insns/match 0xffffffc01019a918, 'tlbi vale1is, x1', 5707 hits, 56597 match hits, Δ+4721 since last match, 33453 avg insns/match 0xffffffc01019a918, 'tlbi vale1is, x1', 5708 hits, 56598 match hits, Δ+10733 since last match, 33453 avg insns/match 0xffffffc01019a918, 'tlbi vale1is, x1', 5709 hits, 56599 match hits, Δ+61959 since last match, 33453 avg insns/match 0xffffffc01019a918, 'tlbi vale1is, x1', 5710 hits, 56600 match hits, Δ+55235 since last match, 33454 avg insns/match 0xffffffc01019a918, 'tlbi vale1is, x1', 5711 hits, 56601 match hits, Δ+54373 since last match, 33454 avg insns/match 0xffffffc01019a918, 'tlbi vale1is, x1', 5712 hits, 56602 match hits, Δ+2705 since last match, 33453 avg insns/match 0xffffffc01019a918, 'tlbi vale1is, x1', 5713 hits, 56603 match hits, Δ+17262 since last match, 33453 avg insns/match 0xffffffc01019a918, 'tlbi vale1is, x1', 5714 hits, 56604 match hits, Δ+17206 since last match, 33453 avg insns/match 0xffffffc01019a918, 'tlbi vale1is, x1', 5715 hits, 56605 match hits, Δ+28940 since last match, 33453 avg insns/match 0xffffffc01019a918, 'tlbi vale1is, x1', 5716 hits, 56606 match hits, Δ+7370 since last match, 33452 avg insns/match 0xffffffc01019a918, 'tlbi vale1is, x1', 5717 hits, 56607 match hits, Δ+7066 since last match, 33452 avg insns/match showing we do some sort of TLBI invalidation every 33 thousand instructions.

| * | tests/plugins/insn: made arg inline not positional and parse it as bool | Mahmoud Mandour | 2021-09-02 | 1 | -2/+12 |
| | | | | | | | | | | | | | | Made argument "inline" not positional, this has two benefits. First is that we adhere to how QEMU passes args generally, by taking the last value of an argument and drop the others. And the second is that this sets up a framework for potentially adding new args easily.

| * | tests/plugin: expand insn test to detect duplicate instructions | Alex Bennée | 2021-02-18 | 1 | -1/+11 |
| | | | | | | | | | | | | | | | | | | | A duplicate insn is one that is appears to be executed twice in a row. This is currently possible due to -icount and cpu_io_recompile() causing a re-translation of a block. On it's own this won't trigger any tests though. The heuristics that the plugin use can't deal with the x86 rep instruction which (validly) will look like executing the same instruction several times. To avoid problems later we tweak the rules for x86 to run the "inline" version of the plugin. This also has the advantage of increasing coverage of the plugin code (see bugfix in previous commit).
