Can you double check that they are in place ? Bruce Hi Bruce! I cloned again the repo to check the branches, and I was able to find them: https://github.com/axxia/axxia_yocto_linux_4.9_pull.git standard/axxia/base-1.15 standard/preempt-rt/axxia/base-1.15 Maybe after a fresh clone instead just a pull, you'll see the branches. Regards, Daniel NOTE: Preempt-rt branch has 4 patches in addition to the standard one. If you add more patches to standard/(preempt-rt)/axxia/base beforehand please notify me. I will rebase our changes so you can do a clean, fast-forward pull. Changes included in this series (axxia tag 1.7 to 1.15): Linux 4.9, Axxia 1.15 Changes Support the Axxia reset driver and, optionally, DDR retention resets. Backport the commits necessary to boot reliably with the Preempt-RT patches and debug configuration. Linux 4.9, Axxia 1.14 Changes Update the PCI LOS work around to make sure the configuration gets put back to normal when the speed changes from gen1 to gen2/gen3. Support additional SPI flash devices (Winbond W25Q128JVSIM and Cypress S25FL128L). EDAC updates: - Change default log settings -- nothing on the console. - Add 6700 support. - Fix issue with DDR retention reset and the use of the scratch register. Only update coresight on 6700 hardware, not simulation. Create a custom gpio driver for Axxia as the interrupt structure is different. Include a device tree for the axm5612. Fix compile errors when CONFIG_PCI_MSI is not defined. Axxia network interface cleanup: - Remove unused reference, CONFIG_NET_VENDOR_LSI. - Include dependecy on Axxia MDIO. Linux 4.9, Axxia 1.13 Changes Update from 4.9.49 to 4.9.61. Linux 4.9, Axxia 1.12 Changes Update coresight hardware tracing support to include all clusters on 6700. Only include coresight in the hardware device trees, not simulation. Update the GPIO driver for 4.9. Include a 12 core device tree for 5600. Fix compile errors when MSI is not enabled. Remove unused reference to CONFIG_NET_VENDOR_LSI. Include dependency on Axxia MDIO when enabling Axxia NEMAC. Linux 4.9, Axxia 1.11 Changes Enable EDAC CMEM support when CMEM gets initialized. Reduce the PCIe LOS work around timeout to 1 second. Update the debug configuration for 5600. Linux 4.9, Axxia 1.10 Changes Rebase from Linux 4.9.36 to 4.9.49. Linux 4.9, Axxia 1.9 Changes Support hardware tracing using coresight and tools/perf (cluster 0 only, 6700 only). Add CCN504 interrupt driven EDAC driver. Linux 4.9, Axxia 1.8 Changes Remove NOSMP configurations. Add support for MSI interruts on 5600 and 6700. APC3000 support. Linux 4.9, Axxia 1.7 Changes Rebase to the latest Yocto (4.9.21 to 4.9.36). Update USB to use the original reset sequence instead of asserting HCRST: - The HCRST reset breaks USB2 and USB3 in some cases. Fixes for PEI configuration 5. Fix a boot problem on 5500. In the new Axxia fault code, exceptions need to be masked on 5500 by default. The final change to the PCI work around (If the link is not established at the requested number of lanes...) was not included. As the hardware does not have the correct default class code, software needs to set it. With the width change work around, the class code needs to be set to the correct value each time the width is changed. Update the default configurations to get rid of some warnings when using systemd instead of sysv init. Add tracing of NCR, PEI, and PCI accesses. Tracing can be enabled using the bootargs or after booting using /sys: - For NCR, use trace for all accesses, and trace_value_read to display the value read after a read. - For PEI and PCI, use trace. PCI Updates: - Add a work around for a hardware problem. If the link is not established at the requested number of lanes, reduce and try again. If there is no link at x1, fail. - Update the LOS work around to work the the lane reduction work around mentioned above. - Add a new configuration for 5600, unsupported on the Axxia development board, configuration 5. - In configuration 2, 5600, set sw_port_1 to 0x2 instead of 0x4. - Always set

[linux-yocto] [yocto-4.12] [PATCH] x86/debug: Handle warnings before the notifier chain, to fix KGDB crash
From: Alexander Shishkin
commit b8347c2196492f4e1cccde3d92fda1cc2cc7de7e upstream
Commit:
9a93848fe787 ("x86/debug: Implement __WARN() using UD0")
turned warnings into UD0, but the fixup code only runs after the
notify_die() chain. This is a problem, in particular, with kgdb,
which kicks in as if it was a BUG().
Fix this by running the fixup code before the notifier chain in
the invalid op handler path.
