| * | tracing/user_events: Use bits vs bytes for enabled status page data | Beau Belgrave | 2022-09-29 | 1 | -7/+18 |
| | | | | | | | | | | | | | | | | | User processes may require many events and when they do the cache performance of a byte index status check is less ideal than a bit index. The previous event limit per-page was 4096, the new limit is 32,768. This change adds a bitwise index to the user_reg struct. Programs check that the bit at status_bit has a bit set within the status page(s).
