The L1 scheduler is a generally useful component that is unfortunately tied quite a bit into the OsmoTRX support. Let's try to separate it out by having separate per-trx/per-ts/per-chan data structures pre-fixed with l1sched_
Using this patch it should be one step easier to use the scheduler for other BTS models, such as the intended upcoming virtual BTS. --- src/osmo-bts-trx/l1_if.c | 35 ++-- src/osmo-bts-trx/l1_if.h | 121 +---------- src/osmo-bts-trx/loops.c | 83 ++++---- src/osmo-bts-trx/loops.h | 14 +- src/osmo-bts-trx/scheduler.c | 486 +++++++++++++++++++++++-------------------- src/osmo-bts-trx/scheduler.h | 143 ++++++++++++- src/osmo-bts-trx/trx_if.c | 2 +- 7 files changed, 473 insertions(+), 411 deletions(-)
