Especially in the Dl after UL case which reflects the commen use case "MS initiates TCP connection", the resulting distribution is not optimal with respect to PDCH usage. This commit changes the implementation to use the slot reservation information instead.

The far more interesting case were to keep the first TBF a little bit longer until the second TBF has been created and delete then. This comes closer the the situation observed with real MS, where the first TBF takes some time (timeout or waiting for Ack) before it gets deleted and thus detached from the MS object. This commit delays the call to tbf_free accordingly. The effect can be observed in the results of the algo A tests, where the uniform distribution of the allocated PDCH is lost.

If there are more than 2 PDCH slots enabled, this slot will conflict with an existing multislot reservation for most multislot classes. This were less likely if the search were reversed and started with the last slot due to the 3 slot shift between Tx and Rx. When multislot allocation is enabled and several MS are connected, and increased rate of poll timeouts can be observed. This commit tries to reduce the number of poll timeouts by reverting the slot search order for SBA allocation.

This might cause issues on the target hardware. This commit disables these LOGP calls unless the ENABLE_TS_ALLOC_DEBUG macro has been set explicitly. This results in a reduction in the CPU usage reported by callgrind for find_multi_slots from 42% to 25% when executing AllocTest.

This commit adds corresponding bit sets which get updated by the attach_tbf/detach_tbf methods of the gprs_rlcmac_pdch class.

This commit reduces the probability for this event by skipping UL slots without free USF while calculation the capacity. Note that the implementation is rather inefficient which will be fixed by the following commits.

This commit adds code to update the reserved set of UL slots to only reserve the single common TS when the UL TBF is allocated. Interestingly this leads to fewer allocated TBF in some cases due to USF exhaustion. This will be improved by the following commit "alloc: Skip common TS without free USF".

This can result in a capacity of 0 and even negative values. This commit forces the capacity of an usable slot to be at least zero under the assumption, that an overly reserved PDCH is still better than none.

Nevertheless UL-only slots will never be used, since only one uplink slot (which must be a common slot) will be used. This patch changes the code to only include common slots in the capacity sum. Note that this might not be optimal if algorithm B supported multiple uplink slots.

So in configurations with many (>4) PDCH, some PDCH are not really used. The new implementation introduced by this commit differs as follows: - The reservation mechanism provided by GprsMs is used to avoid incompatibilities is used in the same way like algo A does. This basically means, that the allocation is done once when the first TBF is requested and then used until all TBF have been released. - All combinations of Rx and Tx slots are checked for compatibility with the multiscot class. Basically the combination with the most usable PDCH and the least number of reservations is used. - Only one UL slots is provided. - Tta and Tra are checked.

This leads to a full reallocation of the PDCH slots, which is possibly incompatible with the old set of slots. This can result in hanging TCP connections and TCP connection failures. This commit replaces the old NULL value by the actual GprsMs object. Since the set_ms() is also done within the tbf_alloc_dl_tbf method, that call is removed.

This statistically prefers the first time slots, especially with short living TBFs. So when the first TBF is triggered by an uplink transfer (which generally results in a short-lived TBF) the potentially longer living DL TBF will be bound to the same slot. When another MS then requests an uplink TBF, it will get the same slot (no UL TBF currently active). This commit changes the algorithm to base its selection on reserved slots instead.

This commit updates find_possible_pdchs() to only consider slots with the same TSC if more that 1 slot shall be assigned. Note that the first PDCH's TSC will be used as reference, so if two or more groups with a common TSC are configured, only the first will be used. This restriction does not apply to algorithm A, since it will not assign more than one slot and therefore sets the max_slots parameter to 1.

Beside the throughput this will also limit the number of TBFs: - number of UL TBFs <= 7 - number of DL TBFs <= 32 This commit changes the allocation algorithm to use the PDCH with the least number of attached TBFs. This will improve the troughput in both directions and the UL limits: - number of UL TBFs <= min(32, N_PDCH * 7) UL TBFs Ticket: #1794 Sponsored-by: On-Waves ehf http://cgit.osmocom.org/osmo-pcu/commit/?id=9380f5d2181c63922627cbff6abe5e3… commit 9380f5d2181c63922627cbff6abe5e3cd05523e4 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Fri Jul 3 12:38:59 2015 +0200 tbf: Add GprsMs* argument to update() and use it in reuse_tbf Since set_ms() is caled on the new DL TBF, the old DL TBF loses the reference to the MS object. This will lead to a segfault, when update() is called in reuse_tbf(). This commit adds an optional GprsMs* parameter to update() and uses it for the slot allocation. This fixes a TbfTest crash that would otherwise occur after applying the next commit.

For additional flexibility, a reverse() function is added to get the opposite direction.

It expects that all of them have the same notion of this. If no TBF is attached, -1 will be returned.

To make the slot allocation load dependant, at least some numbers are required. This commit adds TBF counters (one per direction) and the related methods attach_tbf, detach_tbf, and num_tbfs to gprs_rlcmac_pdch.
