That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (838a3d11815982f89f4ee33024795cfd91c795ae) \ N -- N -- N (520c2919f4bf5d0d0d6dd254e8d76a6876b3b481) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B. Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://cgit.osmocom.org/osmo-pcu/commit/?id=520c2919f4bf5d0d0d6dd254e8d76a68... commit 520c2919f4bf5d0d0d6dd254e8d76a6876b3b481 Author: Jacob Erlbeck <jerlbeck@sysmocom.de> Date: Fri Jul 10 19:52:37 2015 +0200 tbf: Put the TBF list into the PDCH objects (TODO) Currently the TBFs are registered in a TFI indexed array within the TRX objects. TBFs can be searched globally by TFI and TRX number. This conflicts with the use of the same TFI for different TBF on different PDCH. This use case requires the specification of the PDCH as additional search dimension. This commit moves the TFI index TBF arrays into the PDCH objects. The related methods are updated accordingly. Sponsored-by: On-Waves ehf TODO: - corner case tests, e.g. for tfi_find_free - add test cases that crash without this fix - move this commit in front of "Allocate TFI per slot (algorithm A)" to avoid a non-operational version http://cgit.osmocom.org/osmo-pcu/commit/?id=509fdb69a9e2036b55cac7f954f9343b... commit 509fdb69a9e2036b55cac7f954f9343b6c77d5af Author: Jacob Erlbeck <jerlbeck@sysmocom.de> Date: Fri Jul 10 12:25:25 2015 +0200 alloc: Allocate TFI per slot (algorithm A) Currently the TFI are managed per TRX, thus only a maximum of 32 TBF per direction and per TRX are possible simultaneously. This commit modifies algorithm_a() to allow the sharing of TFI between different PDCH. Since algorithm A only assigns a single slot to each TBF, the TFI of each PDCH can be assigned independently. This increases the maximum to 32 TBF per direction and per PDCH concerning the TFI allocation.

This does fit to TFI reuse for different slots, since this were tightly coupled with the slot selection. This commit just moves the TFI selection into the alloc_algorithm functions. The tfi parameter is removed from the the TFI alloc functions. The trx parameter is changed into use_trx to optionally limit the trx selection (same semantics like in tfi_find_free).

Since the namespaces of UL and DL TFI are separate, this implementation is not correct. This commit changes gprs_rlcmac_pdch to use a separate bit set for each direction. It also replace the corresponding conditional fprintf statement in check_tfi_usage (AllocTest.cpp) by an equivalent OSMO_ASSERT.

It iterates through all TBFs, records on which PDCH it uses which TFI and check for conflicts. It also checks the bits returned by pdch->assigned_tfi(). The latter suffers from an bug in that method (no separation of uplink and downlink), so a conditional fprintf is used instead of an assertion.

These values may only interpreted as 0, if frequency hopping is not enabled and if there is no change from Rx to Tx or vice-versa. This commit sets Ttb/Trb to 1 if the table entry is MS_B/MS_C, since only combined down/up access modes are supported.

This does not make much sense for class type 2 MS, since those are capable to work in full duplex mode. This commit sets the masks to 0xff for class type 2 MS.

Currently either value can be used which might result in combinations not covered by the spec. This commit changes find_multi_slots() to skip non-compliant combinations. Note that this code will have to be extended, if other medium access modes are implemented.

This commit merge both functions and adds a parameter containing a function for that compuation.
