The modification is no longer needed, since the call to update has been removed from reuse_tbf(). Conflicts: src/tbf_dl.cpp Sponsored-by: On-Waves ehf http://cgit.osmocom.org/osmo-pcu/commit/?id=07111668d4b4bfe44c02077b29ed7d3… commit 07111668d4b4bfe44c02077b29ed7d3cb8415134 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Mon Jun 29 13:30:43 2015 +0200 tbf: Remove call to update() in reuse_tbf Since both TBF are based on the same reservation which means that they should be compatible with respect to the slot usage, and since the new TBF has not been forced to single slot usage, an update of the allocation is not necessary now. This commit removes the call to update() from within reuse_tbf(). Sponsored-by: On-Waves ehf http://cgit.osmocom.org/osmo-pcu/commit/?id=4944c195d4a71f4aa5d9a3274907fa0… commit 4944c195d4a71f4aa5d9a3274907fa0bfed0e6ce Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Thu Jul 2 12:04:20 2015 +0200 tbf: Set ms in call to tbf_alloc_dl_tbf The call to tbf_alloc_dl_tbf misses the pointer to the GprsMs object which is already known in that case (tbf_reuse). 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.

They correspond to the potential use of the PDCHs and can be used to achieve a more uniform slot allocation. This commit adds bit set based methods to GprsMs and gprs_rlcmac_trx and a counter to gprs_rlcmac_pdch. The current TRX will also be stored in the MS object.

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.

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 (7c04380a7051eccf4049f534924f41205609c8e3) \ N -- N -- N (410d98e5d0c0eae76221a2d62a837b962f082506) 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=410d98e5d0c0eae76221a2d62a837b9… commit 410d98e5d0c0eae76221a2d62a837b962f082506 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Thu Jul 2 15:48:25 2015 +0200 alloc: Use least reserved PDCH for algo A (TODO) TODO: - unify find_least_reserved_pdch and find_least_busy_pdch or - force find_multi_slots to single slot reservation http://cgit.osmocom.org/osmo-pcu/commit/?id=eff0c350c848c642efad7ebe478a52c… commit eff0c350c848c642efad7ebe478a52c2c8c351ce Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Thu Jul 2 15:10:20 2015 +0200 Revert "ms: Delay the call to set_reserved_slots(NULL, 0,0) (EXPERIMENTAL)" This reverts commit 341c9189caf00c077ef73138d087bf29e3ae12d1. http://cgit.osmocom.org/osmo-pcu/commit/?id=a0ea29a5968308224b24b8718a8baa0… commit a0ea29a5968308224b24b8718a8baa09806ad645 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Thu Jul 2 14:35:57 2015 +0200 FIXUP bts: Add Poll Timeout counter (TODO) http://cgit.osmocom.org/osmo-pcu/commit/?id=bdcfb71161aed1dd882ec7f9dcc4880… commit bdcfb71161aed1dd882ec7f9dcc4880146175155 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Thu Jul 2 13:19:49 2015 +0200 sba: Reverse TS search order (TODO) - when using multiple TS the first TS cannot be used for UL eventually if a TBF is still active or releasing. - Currently RACH requests are often accompanied by poll timeouts - This cannot prevent them completely (especially with multiple TRX in the future) http://cgit.osmocom.org/osmo-pcu/commit/?id=70960fb90cf4ab5efa2851f6927e53b… commit 70960fb90cf4ab5efa2851f6927e53bb14878512 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Thu Jul 2 12:54:26 2015 +0200 bts: Add Poll Timeout counter (TODO) http://cgit.osmocom.org/osmo-pcu/commit/?id=9eb88f2348ce449deac1022950998ec… commit 9eb88f2348ce449deac1022950998ecef372a67b Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Thu Jul 2 12:34:26 2015 +0200 tbf: Remove call to update() in reuse_tbf (TODO) http://cgit.osmocom.org/osmo-pcu/commit/?id=5ef6a6028a1ed8aa59d3b2a701d53e4… commit 5ef6a6028a1ed8aa59d3b2a701d53e4737c15478 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Thu Jul 2 12:04:20 2015 +0200 tbf: Set ms in call to tbf_alloc_dl_tbf (TODO) - reuse - alloc didn't know slot reservation TODO: - cm http://cgit.osmocom.org/osmo-pcu/commit/?id=341c9189caf00c077ef73138d087bf2… commit 341c9189caf00c077ef73138d087bf29e3ae12d1 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Thu Jul 2 10:48:09 2015 +0200 ms: Delay the call to set_reserved_slots(NULL, 0,0) (EXPERIMENTAL) TODO: - Check whether this fixes the issues. http://cgit.osmocom.org/osmo-pcu/commit/?id=f5082f9372efa00090519a1b133b7ee… commit f5082f9372efa00090519a1b133b7eee88ea0d61 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Thu Jul 2 10:47:37 2015 +0200 ms: Clear the reserved slots in the destructor (FIXUP) http://cgit.osmocom.org/osmo-pcu/commit/?id=6b3a27be054a2cc4667a22a4c435cd5… commit 6b3a27be054a2cc4667a22a4c435cd5d7ecb59ce Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Tue Jun 30 14:48:13 2015 +0200 alloc: Disable inner loop debugging by default (TODO) Callgrind: 42%-> 25% http://cgit.osmocom.org/osmo-pcu/commit/?id=596f547a378786b2a9dea5a3b1e6182… commit 596f547a378786b2a9dea5a3b1e6182abf794e60 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Tue Jun 30 14:34:24 2015 +0200 alloc: Optimize find_free_usf According to callgrind, this function consumes 33% CPU when running the AllocTest program.

Note that this might not be optimal if algorithm B supported multiple uplink slots.

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.

They correspond to the potential use of the PDCHs and can be used to achieve a more uniform slot allocation. This commit adds bit set based methods to GprsMs and gprs_rlcmac_trx and a counter to gprs_rlcmac_pdch. The current TRX will also be stored in the MS object.
