linux-yocto/3.10: fix long perf compile times

2013-09-18T18:49:41+00:00

perf's builtin-sched.c triggers extremly long build times on some architectures due to gcc 4.7+ var-tracking functionality. To fix this, we can cherry pick the 3.12 commit: f36f83f94 [perf sched: Move struct perf_sched definition out of cmd_sched()] With this change build times are reduced from 15 to 20 minutes for qemuarm to: real 2m19.940s user 1m35.438s sys 0m11.165s For kernel's that are not carrying this patch, the following can be added to the perf recipe to also fix the issue: +++ b/meta/recipes-kernel/perf/perf.bb @@ -68,6 +68,7 @@ EXTRA_OEMAKE = \ CC="${CC}" \ AR="${AR}" \ perfexecdir=${libexecdir} \ + EXTRA_CFLAGS="-fno-var-tracking" \ NO_GTK2=1 ${TUI_DEFINES} NO_DWARF=1 ${SCRIPTING_DEFINES} \ (From OE-Core rev: 82ad5305381c2f541ef051a8fc28243cd91776fe) Signed-off-by: Bruce Ashfield Signed-off-by: Richard Purdie

linux-yocto/3.10: mips configuration changes

2013-09-18T18:49:41+00:00

Updating the 3.10 SRCREV to import the following MIPS configuration changes 4f689aa meta: remove ftrace/ftrace-disable feature 3058d81 mips: have the mips BSPs disable function tracing instead of ftrace 935f43f meta: add ftrace/ftrace-function-tracer-disable feature 0d72a03 mti-malta64: Default to support o32 and n32 userspace binaries The first three changes improve the ftrace disabling fragments, to allow tracepoints and ftrace to be enabled, while only disabling dynamic ftrace. This allows tools that required tracepoints (like lttng) to be built against MIPS. The mti-malta64 change adds n32 and o32 support to the default configuration to support a broader range of userspace binaries.

perf: Add LDFLAGS to allow build of old kernels without patching

2013-09-18T16:54:42+00:00

The LDFLAGS is required or some old kernels fails due missing symbols and this is preferred than requiring patches to every old supported kernel. Fixes [YOCTO: #5221] (From OE-Core rev: 0eccbf2016e89e6f1c3796f138b02a508d2edbcf) Signed-off-by: Otavio Salvador Signed-off-by: Richard Purdie

qemurunner: disable grabs in automated testing

2013-09-18T16:52:04+00:00

Use the new QEMU_DONT_GRAB environment variable to disable grabs, finally/hopefully solving the random hangs that the autobuilder has been hitting for a while. [ YOCTO #5131 ] (From OE-Core rev: 32f9575a565f350649264c11eceba8311584b0fd) Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

qemu: add option to disable X grabs

2013-09-18T16:52:04+00:00

When the mouse pointer enters the qemu window it takes a pointer grab. This doesn't sound too dangerous at first but it turns out that SDL will infinitely busy-loop if it can't get the grab (e.g. if the screen is locked) and the average autobuilder setup's X server will have locked the screen a few minutes after boot. The result is that on many autobuilders apparently random qemu instances (the top-most one under the pointer) will hang during boot. To resolve this add an option (via an environment variable) to never attempt a grab. The default behaviour remains to grab so that everyone else doesn't see any change.

u-boot-fw-utils: Skip package if UBOOT_MACHINE is unset

2013-09-18T13:18:08+00:00

The UBOOT_MACHINE variable needs to be set so the firmware utils can know about some configuration settings which are board dependent. This patch ensures the package is skipped in case UBOOT_MACHINE is unset thus avoid its build in 'bitbake world' builds for incompatible machines.

bitbake: data_smart: Fix variable reference issues

2013-09-18T12:27:30+00:00

The change to use the expansion cache in VariableParse was incorrect as it was adding in references it shouldn't have been. This patch corrects the codepaths and ensures the references are correct. The cache version is bumped since the previous bug could have leave to invalid checksum calculations and a clean cache is therefore desireable. The impact of the bug was that sstate was not getting reused when it should and some tasks were also being rerun when they should not have been.

bitbake: cooker: return a copy checkPackages

2013-09-18T07:41:55+00:00

The syntax used for checkPackages implies a copy is returned but it did not do so. Make it so. This is fixes universe builds where error messaages were being shown but there should have only been warnings.

bitbake: usermanual.xml: Two new sections added to BitBake "Description"

2013-09-17T21:27:56+00:00

1. Added a new section "Appending and Prepending (override style syntax)". This section shows how the append and prepend operators work using the override style syntax. 2. Added a new section "Removing (override style syntax)". This section describes the new "_remove" operator.
