Upstreaming effort

Bootlin maintains a number of branches reflecting the in-progress upstream work. They are based on 4.14.y. Those branches are available in the public Git repository at https://github.com/MISL-EBU-System-SW/mainline-public. The logic is as follows:

  • devel-4.14/<topic> are topic branches for work in progress, not yet merged upstream. Such branches are based on backport-4.14 (there are exceptions), and are rebased as needed
  • devel-4.14/all which is a branch resulting of the merge of all the devel-4.14/<topic> branches

These branches are:

  • backport-4.14 is based on v4.14.58, with patches backported from upstream, i.e patches that had already been accepted. This branch is generally not rebased, but we rebased it to 4.14.58 recently.
  • devel-4.14/a8kp-doc introduces the 8KP support, in the documentation. Based on devel-4.14/icu-sei-overheat.
  • devel-4.14/a8kp-drivers introduces the 8KP support, in the drivers.
  • devel-4.14/a8kp-dt64 introduces the 8KP support, in the device trees. Based on devel-4.14/dt64.
  • devel-4.14/comphy
  • devel-4.14/custom-defconfig64 contains out of tree patches to enable Marvell EBU specific drivers in the ARM64 defconfig. Based on devel-4.14/defconfig64.
  • devel-4.14/defconfig64 contains the ARM64 defconfig specific patches.
  • devel-4.14/dt64 contains all the ARM64 Device Tree updates. They are regrouped in a single topic branches to avoid conflicts.
  • devel-4.14/icu-sei-overheat contains improvements for the interrupts and thermal drivers.
  • devel-4.14/pm-a3700 contains patches adding suspend/resume support for the a3700.
  • devel-4.14/pcie contains fixes and improvements to the PCI support for Marvell SoCs, especially the pci-mvebu and pci-aardvark drivers
  • devel-4.14/ppv2 contains fixes and improvements in the mvpp2 network driver.

Commands used to generate the devel-4.14/all branch (so that topic branches are always merged in the same order) :

git reset --hard backport-4.14
git merge devel-4.14/comphy devel-4.14/ppv2 devel-4.14/crypto devel-4.14/pcie devel-4.14/mvneta devel-4.14/icu-sei-overheat devel-4.14/dt64 devel-4.14/a8kp-dt64 devel-4.14/a8kp-drivers devel-4.14/a8kp-doc devel-4.14/defconfig64 devel-4.14/custom-defconfig64 devel-4.14/pm-a3700
