There are 3 options for those using CAN bus: 1- set sysctl net.core.default_qdisc back to pfifo_fast 2- remove CONFIG_NET_SCH_FQ_CODEL kernel option 3- apply kernel patch from https://lore.kernel.org/netdev/20190327165632.10711-1-...@pengutronix.de/t/#m5f86a2d284d8c8cf11d2f1786575b10fe4be5eb6
Third option is what I prefer, but it depends on kernel patching policy ;) Le mar. 22 oct. 2019 à 15:44, Mittal, Anuj <anuj.mit...@intel.com> a écrit : > > Thanks, it's coming from here: > > https://git.yoctoproject.org/cgit/cgit.cgi/yocto-kernel-cache/commit/?h=yocto-4.19&id=e73568c48e08a0cefa34a689e2f06f60abd17aec > > From the discussion, it looks like this is something that'd be fixed in > kernel? > > Thanks, > > Anuj > > On Tue, 2019-10-22 at 11:43 +0200, Vincent Prince wrote: > > Hi, > > > > Just a warning for those using CAN bus: > > > > Not sure where it comes from but the following option changes from > > "not set" to "m": CONFIG_NET_SCH_FQ_CODEL. > > With previous kernels, "net.core.default_qdisc = fq_codel" sysctl > > option didn't work and it fall back to pfifo_fast. > > > > For CAN bus system, fq_codel fairqueue is inappropriate as it drops > > packets, so for those who uses CAN bus, > > be careful to check your settings (ip addr show can0 // sysctl > > net.core.default_qdisc) > > > > For more details, see https://github.com/systemd/systemd/issues/9194 > > issue thread. > > > > Best regards, > > Vincent > > > > > > Le lun. 14 oct. 2019 à 07:55, Naveen Saini < > > naveen.kumar.sa...@intel.com> a écrit : > > > Also updated kmeta > > > > > > tag 'v4.19.73': (247 commits) > > > Linux 4.19.73 > > > Merge "USB: Fix configuration selection issues introduced in > > > v4.20.0" > > > vhost: make sure log_num < in_num > > > powerpc/tm: Fix restoring FP/VMX facility incorrectly on interrupts > > > powerpc/tm: Remove msr_tm_active() > > > PCI: Reset both NVIDIA GPU and HDA in ThinkPad P50 workaround > > > ext4: unsigned int compared against zero > > > ext4: fix block validity checks for journal inodes using indirect > > > blocks > > > ext4: don't perform block validity checks on the journal inode > > > drm/atomic_helper: Allow DPMS On<->Off changes for unregistered > > > connectors > > > virtio/s390: fix race on airq_areas[] > > > drm/i915: Make sure cdclk is high enough for DP audio on VLV/CHV > > > bcache: fix race in btree_flush_write() > > > bcache: add comments for mutex_lock(&b->write_lock) > > > bcache: only clear BTREE_NODE_dirty bit when it is set > > > NFSv4: Fix delegation state recovery > > > iio: adc: gyroadc: fix uninitialized return code > > > mm/migrate.c: initialize pud_entry in migrate_vma() > > > i2c: at91: fix clk_offset for sama5d2 > > > i2c: at91: disable TXRDY interrupt after sending data > > > gpio: don't WARN() on NULL descs if gpiolib is disabled > > > ... > > > > > > Signed-off-by: Naveen Saini <naveen.kumar.sa...@intel.com> > > > Signed-off-by: Anuj Mittal <anuj.mit...@intel.com> > > > --- > > > recipes-kernel/linux/linux-intel_4.19.bb | 6 +++--- > > > 1 file changed, 3 insertions(+), 3 deletions(-) > > > > > > diff --git a/recipes-kernel/linux/linux-intel_4.19.bb b/recipes- > > > kernel/linux/linux-intel_4.19.bb > > > index ae059b4..7e26cd0 100644 > > > --- a/recipes-kernel/linux/linux-intel_4.19.bb > > > +++ b/recipes-kernel/linux/linux-intel_4.19.bb > > > @@ -9,9 +9,9 @@ SRC_URI_append = " > > > file://0001-menuconfig-mconf-cfg-Allow-specification-of-ncurs > > > > > > DEPENDS += "elfutils-native openssl-native util-linux-native" > > > > > > -LINUX_VERSION ?= "4.19.68" > > > -SRCREV_machine ?= "1e852a3597a92ce329cf55a3c86a1c2cae3afc6f" > > > -SRCREV_meta ?= "e73568c48e08a0cefa34a689e2f06f60abd17aec" > > > +LINUX_VERSION ?= "4.19.73" > > > +SRCREV_machine ?= "ca05e9cd64b5afbd698fa2707be4d2602890b849" > > > +SRCREV_meta ?= "a7cb57afb9fb9787079c28a1028d797632105e56" > > > > > > # For Crystalforest and Romley > > > KERNEL_MODULE_AUTOLOAD_append_core2-32-intel-common = " uio" > > > -- > > > 2.7.4 > > > -- _______________________________________________ meta-intel mailing list meta-intel@yoctoproject.org https://lists.yoctoproject.org/listinfo/meta-intel
