2018-06-14linux-yocto-4.9: KVM backports for Spectre/Meltdown up till 4.9.88Awais Belal
The upcoming mitigations for Spectre/Meltdown are addressed in a way that a patch contains fixes on a topic for both normal/KVM running modes. If we do not backport the earlier KVM patches the conflicts will be very hard to resolve. Signed-off-by: Awais Belal <awais_belal@mentor.com>
2018-05-22linux-yocto/rt: adjust spectre/meltdown backportsAwais Belal
This includes spectre/meltdown backports for the RT kernel as well by moving the patches fragment to the common include. A patch that conflicts with RT changes has been taken out of the backport set and added separately for both type of kernels after adjusting accordingly. Signed-off-by: Awais Belal <awais_belal@mentor.com>

2018-05-10linux-yocto/4.9: fix bpf backports for spectre/meltdownAwais Belal
A commit was missed during backports which generates failure during build. This now picks that commit up as well and updates the series appropriately. Signed-off-by: Awais Belal <awais_belal@mentor.com>
2018-04-04linux-yocto_4.9: move upstream backports to common layerAwais Belal
This moves the upstream backports to the common layer and uses an append to apply these so the same could be used for other common changes. Signed-off-by: Awais Belal <awais_belal@mentor.com>
2018-04-03linux-yocto: move 4.9 recipe to commonAwais Belal
The kernel 4.9 recipe is being used for v1000 as well as snowyowl. Move the base recipe to common and then use appends for BSP overrides. Signed-off-by: Awais Belal <awais_belal@mentor.com>

2017-03-31steppeeagle: disable DEBUG_PREEMPT and DEBUG_RODATAAwais Belal
These configurations conflict with KGDB debugging in some cases and generate stack dumps in various other situations. The stack dumps related to mwaitx are properly fixed through https://patchwork.kernel.org/patch/8549611/ but the mentioned patch is only available for Yocto kernel 4.8 and we don't use these so it is much better to avoid the problem with this for the time being rather than backporting the patch.

2016-11-23linux-yocto: pick up random optimizationsAwais Belal
This enables the chacha20 scheme of random number generator which is way more optimized and efficient from the legacy non-blocking pool. This helps providing a steady and more robust random mechanism which allows for better boot times and other positives. The included patch has been back ported from linux-yocto 4.8 tree and adjusted accordingly.

2016-10-14linux-yocto: fix SRCREVsAwais Belal
This explicitly locks the source to particular SRCREVs otherwise an upstream move can break our builds and we also want to support BB_NO_NETWORK builds. Signed-off-by: Awais Belal <awais_belal@mentor.com>
2016-10-14SE/BE: move to 4.4 kernelAwais Belal
This commit does a few things which cannot be separated easily so it cannot be split in to separate commits. * Drops all 4.1 kernel bits. * Moves all common patches from meta-amdfalconx86 to common. * Moves SE/BE builds to 4.4 kernel. Signed-off-by: Awais Belal <awais_belal@mentor.com>

The AMD Stoney platform uses a new device id 0x15b3 for its HDMI audio which currently isn't available in the PCI device list for Azalia compatible devices. We now add this device so it correctly shows up as HDMI rather than a generic one. Signed-off-by: Awais Belal <awais_belal@mentor.com>

2016-05-16linux-yocto-rt: fix RT builds and move to commonAwais Belal
During consolidation of the kernel recipes for standard kernel some changes were made to the linux-yocto-amd-4.1.inc which was being utilized b/w standard and RT kernel for the amdfalconx86 machine. These updates rendered void many features on the RT kernel along with making the build of this kernel unstable. We now move the RT kernel recipe to common layer so it can be utilized by other machines and fix the issues that were present prior to the move. Signed-off-by: Awais Belal <awais_belal@mentor.com>
