/*
 * Conventions on Event Names:
 *
 * - The prefix determines something about how the timeline should be
 *   displayed, and is split up into various parts, separated by underscores:
 *  - 'SW' and 'HW' as the first part will be used to determine whether a
 *     timeline is to do with Software or Hardware - effectively, separate
 *     'channels' for Software and Hardware
 *  - 'START', 'STOP', 'ENTER', 'LEAVE' can be used in the second part, and
 *    signify related pairs of events - these are optional.
 *  - 'FLOW' indicates a generic event, which can use dependencies
 * - This gives events such as:
 *  - 'SW_ENTER_FOO'
 *  - 'SW_LEAVE_FOO'
 *  - 'SW_FLOW_BAR_1'
 *  - 'SW_FLOW_BAR_2'
 *  - 'HW_START_BAZ'
 *  - 'HW_STOP_BAZ'
 * - And an unadorned HW event:
 *  - 'HW_BAZ_FROZBOZ'
 */

/*
 * Conventions on parameter names:
 * - anything with 'instance' in the name will have a separate timeline based
 *   on that instances.
 * - underscored-prefixed parameters will by hidden by default on timelines
 *
 * Hence:
 * - Different job slots have their own 'instance', based on the instance value
 * - Per-context info (e.g. atoms on a context) have their own 'instance'
 *   (i.e. each context should be on a different timeline)
 *
 * Note that globally-shared resources can be tagged with a tgid, but we don't
 * want an instance per context:
 * - There's no point having separate Job Slot timelines for each context, that
 *   would be confusing - there's only really 3 job slots!
 * - There's no point having separate Shader-powered timelines for each
 *   context, that would be confusing - all shader cores (whether it be 4, 8,
 *   etc) are shared in the system.
