2020-10-17devtool: make sure .git/info exists before writing to .git/info/excludesRoland Hieber
If nothing else is specified, 'git init' uses its default repository template from the install location (e.g. /usr/share/git-core/templates), which already includes an info/ subdirectory. However, when setting init.templateDir to a different template path in ~/.gitconfig, this isn't necessarily the case, and it can lead to setup_git_repo() failing with stack traces like: File: '.../scripts/lib/devtool/__init__.py', lineno: 234, function: setup_git_repo 0230: pass 0231: if 'singletask.lock\n' not in excludes: 0232: excludes.append('singletask.lock\n') 0233: bb.warn("try writing excludefile") *** 0234: with open(excludefile, 'w') as f: 0235: for line in excludes: 0236: f.write(line) 0237: 0238: bb.process.run('git checkout -b %s' % devbranch, cwd=repodir) Exception: FileNotFoundError: [Errno 2] No such file or directory: '.../devtooltmp-6m36b181/workdir/foobar-1.0.1/.git/info/exclude' Fix this edge case by creating the .git/info/ directory first.

2020-10-08qemumips: use 34Kf-64tlb CPU emulationVictor Kamensky
In order to improve performance of qemumips autobuilder test runs, let's use 34Kf-64tlb cpu type that was introduced in OE version of qemu. 34Kf-64tlb cpu type is identical to 34Kf but it has 64 TLBs configure vs original 16 TLBs. The change in number of TLBs in emulated CPU reduces TLB trash and reduces number of times TLB refill kernel code runs, and therefore siginificantly improves tests execution time. Note 34Kf-64tlb qemu cpu type does not exist in upstream, so far it is added as patch in OE. See qemu 34Kf-64tlb cpu addition commit for more details.

2020-10-08qemu: add 34Kf-64tlb fictitious cpu typeVictor Kamensky
In Yocto Project PR 13992 it was reported that qemumips in autobuilder runs almost twice slower then qemumips64 and some times hit time out. Upon investigations of qemu-system with perf, gdb, and SystemTap and comparing qemumips and qemumips64 machines behavior it was noticed that qemu soft mmu code behaves quite different and in case if qemumips tlbwr instruction called 16 times more oftern. It happens that in qemumips64 case qemu runs with cpu type that contains 64 TLB, but in case of qemumips qemu runs with cpu type that contains only 16 TLBs. The idea of proposed qemu patch is to introduce fictitious 34Kf-64tlb cpu type that defined exactly as 34Kf but has 64 TLBs, instead of original 16 TLBs. Testing of core-image-full-cmdline:do_testimage with 34Kf-64tlb shows 40% or so test execution real time improvement. Note for future porters of the patch: easiest way to update the patch and be in sync with 34Kf definition is to copy 34Kf machine definition and apply the following changes to it (just change 15 to 63 of CP0C1_MMU bits value) [kamensky@coreos-lnx2 qemu]$ diff ~/34Kf.c ~/34Kf-64tlb.c 2c2 < .name = "34Kf", > .name = "34Kf-64tlb", 6c6 < .CP0_Config1 = MIPS_CONFIG1 | (1 << CP0C1_FP) | (15 << CP0C1_MMU) | > .CP0_Config1 = MIPS_CONFIG1 | (1 << CP0C1_FP) | (63 << CP0C1_MMU) | Fixes https://bugzilla.yoctoproject.org/show_bug.cgi?id=13992 Upstream Status: Inappropriate Signed-off-by: Victor Kamensky <kamensky@cisco.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

2020-10-08devtool: fix modify with patches in override directoriesRoss Burton
If a recipe applies patches which are in machine-specific override directories, devtool will fail to fetch the patches that don't match the default configuration. For example where there are patches at qemux86/x86.patch and qemuarm/arm.patch: SRC_URI = "file://source" SRC_URI_append_qemuarm = " file://arm.patch" SRC_URI_append_qemux86 = " file://x86.patch" The patch apply phase sets OVERRIDES but does not set FILESOVERRIDES, so it cannot find the patch files as the search path isn't correct. Fix this by setting FILESOVERRIDES too. Also when iterating through the overrides we need to be sure that other overrides that are used are not enabled, so extend no_overrides instead of simply appending the current override.

2020-10-07base/bitbake.conf: Enable pseudo path filteringRichard Purdie
This is a pretty big change to the way pseudo operates when used in OpenEmbedded. Normally, pseudo monitors and logs (adds to its database) any file created or modified whilst in a fakeroot environment. There are large numbers of files we simply don't care about the permissions of whilst in that fakeroot context, for example ${S}, ${B}, ${T}, ${SSTATE_DIR}, the central sstate control directories, This change uses new functionality in pseudo to ignore these directory trees, resulting in a cleaner database with less chance of "stray" mismatches if files are modified outside pseudo context. It also should reduce some overhead from pseudo as the interprocess round trip to the server is avoided. There is a possible complication where some existing recipe may break, for example, we found a recipe which was writing to "${B}/install" for "make install" in do_install and since we listed ${B} as not to be tracked, there were errors trying to chown root for files in this location. This patch fixes a few corner cases in OE-Core when used with this new ignore list: * The archiver directory matched a "${WORKDIR}/deploy*" pattern so was renamed to something else since that directory does need its root permissions * The ${S} and ${B} ignoring is conditional on them being different to ${WORKDIR} * package_write_* task output (the debs/rpms/ipks) are now owned by the build user so we don't want the file ownership information in the hashequiv outhash calculation even if they are built under pseudo. * The fontcache postinstall intercept is run under qemu outside of pseudo context so delete files it may delete up front where pseudo can see this. * SSTATE_DIR is in PSEUDO_PATHS_IGNORE, which is in FAKEROOTENV which is cached by bitbake. We therefore need to trigger reparsing if this changes, which means SSTATE_DIR can be in BB_HASHBASE_WHITELIST but not BB_HASHCONFIG_WHITELIST. Rework the variables to handle this. This otherwise breaks some of our sstate tests in oe-selftest. * Ignore the temp directory wic uses for rebuilding rootfs. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
