bitbake: siggen: Fix hashequiv performance issues

2019-12-12T13:15:00+00:00

We're seeing huge slowdowns on large builds on the autobuilder. A qemux86 world build was running really slowly, a primary feature was lots of rehashing going on due to an sstate change which caused a rebuild when all output should be identical. This was traced to the hundreds of thousands of calls to get_unihash() from get_taskash(). If we simplify the unitaskhashes data structure, we can bypass the function call and access the data directly. In local profile charts, this significanly sped up process_possible_migrations(), both on profiles and visually. Whilst this change doesn't aid readability, it does solve an otherwise huge performance issue. (Bitbake rev: c4b8440f730c33eaf9f818b856ae81b2f1017fec) Signed-off-by: Richard Purdie

bitbake: runqueue: Batch scenequeue updates

2019-12-12T13:15:00+00:00

Batch all updates to scenequeue data together in a single invocation instead of checking each task serially. This allows the checks for sstate object to happen in parallel, and also makes sure the log statement only happens once (per set of rehashes).

2019-12-11T11:59:49+00:00

This avoids a directory not present error. Fix a comment typo whilst here. (From OE-Core rev: 1360d8d7d99b70a80c8cdbc1fc6d9e6752483139) Signed-off-by: Richard Purdie

sstate: Ensure target sstate directory exists if unihash changes

2019-12-11T10:09:39+00:00

The previous patches meant the mkdir might no longer match the final target directory. Fix this. (From OE-Core rev: 0af4dae84099e8632a9ea6a4afdbea2f232bb170) Signed-off-by: Richard Purdie
