118c273ab00223876ab4db154df39d03fa644c55 - event: enable changing back to static scheduler

Fri, 30 Aug 2024 15:49:02 +0000

event: enable changing back to static schedulerThis requires saving the original core for each thread. Thankfullyit is very easy to just store it in the spdk_lw_thread. Then wejust run ->balance() once after the static scheduler is re-installedto put all of the threads back to their original lcores, and takeall cores out of interrupt mode.Note: 82c466 required bumping SO_VER due to adding trace_id tostruct spdk_reactor. But that didn't change the size of the structure.For some unexplained reason, adding initial_lcore to the privatestruct lw_thread in this patch results in abidiff no longer reportingthe trace_id change, and check_so_deps.sh fails saying the SO_VERbump is no longer needed. A patch that simply adds the initial_lcoremember, with no other code changes, triggers the same error.Signed-off-by: Jim Harris Change-Id: I9d1ace726617d95f89f42959c9c2c36602fb7f77Reviewed-on: https://review.spdk.io/gerrit/c/spdk/spdk/+/24765Community-CI: Broadcom CI Reviewed-by: Changpeng Liu Reviewed-by: Konrad Sztyber Community-CI: Mellanox Build BotTested-by: SPDK CI Jenkins List of files: /spdk/lib/event/Makefile

Contribution date used"--follow -C95%" to get the most accurate date.Note that several files in this patch didn't end the license/(c)block with a blank comment line so these were added as the vastmajority of files do have this last blank line.

488570ebd418ba07c9e69e65106dcc964f3bb41b - Replace most BSD 3-clause license text with SPDX identifier.

Fri, 03 Jun 2022 19:15:11 +0000

Replace most BSD 3-clause license text with SPDX identifier.Many open source projects have moved to using SPDX identifiersto specify license information, reducing the amount ofboilerplate code in every source file. This patch replacesthe bulk of SPDK .c, .cpp and Makefiles with the BSD-3-Clauseidentifier.Almost all of these files share the exact same license text,and this patch only modifies the files that contain themost common license text. There can be slight variationsbecause the third clause contains company names - most say"Intel Corporation", but there are instances for Nvidia,Samsung, Eideticom and even "the copyright holder".Used a bash script to automate replacement of the license textwith SPDX identifier which is checked into scripts/spdx.sh.Signed-off-by: Jim Harris Change-Id: Iaa88ab5e92ea471691dc298cfe41ebfb5d169780Reviewed-on: https://review.spdk.io/gerrit/c/spdk/spdk/+/12904Community-CI: Broadcom CI Community-CI: Mellanox Build BotTested-by: SPDK CI Jenkins Reviewed-by: Aleksey Marchuk Reviewed-by: Changpeng Liu Reviewed-by: Dong Yi Reviewed-by: Konrad Sztyber Reviewed-by: Paul Luse Reviewed-by: List of files: /spdk/lib/event/Makefile
