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=520c2919f4bf5d0d0d6dd254e8d76a6… commit 520c2919f4bf5d0d0d6dd254e8d76a6876b3b481 Author: Jacob Erlbeck <jerlbeck(a)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.

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.

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 is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "UNNAMED PROJECT". The branch, jerlbeck/master has been updated discards 377250f3ada5701a104ccb5388bfe13640b53eb7 (commit) via c91c18e6ef9ee5fca3d10b57ebddf211d3655a8d (commit) This update added new revisions after undoing existing revisions. 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 (377250f3ada5701a104ccb5388bfe13640b53eb7) \ N -- N -- N (c91c18e6ef9ee5fca3d10b57ebddf211d3655a8d) 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 ----------------------------------------------------------------- ----------------------------------------------------------------------- Summary of changes: hooks/post-receive -- UNNAMED PROJECT
