• And Google is mandating Kernel version 4.4 for Oreo (because of hardening security features).

This means Sony will have a kernel 4.4 for their Xperia X F5121 hardware platform [as seen on the current unofficial AOSP test builds.

It would be awesome if Jolla could also provide this updated kernel in one of the next uprages of Sailfish X.

(This could potentially bring new extra security protections, and even a bunch of features introduced that the current 3.10 lacks)

update

Ressource :

• Sony's page with their progress on the official kernel 4.4 port
• Sony's github with their current kernel development

Also :

µSDXC fixes :

• Users report having problems with some µSDXC cards
• one TMO user reports consistently having the same card accepted by stock android, and completely unseen by Sailfish X
• One interesting answer points to known kernel bugs (which could explain why Up-to-date Android's 3.10.1xx kernel can detect the card, but Sailfish X's slightly older 3.10.84 misses it)

This kind of bugs would be a very good argument for Jolla to try to follow as closely as possible the updates that Sony makes available of their kernel for Xperia X.X.1

Meltdown & Spectre

As underlined by another request on TJC : according to ARM the Cortex-A72 core that is found inside Sony Xperia X' Snapdragon 650, is vulnerable to Spectre variation 1 (Bounds Check Bypass) and Spectre varation 2 (Branch Target Injection) - (And also a distant cousin of Meltdown Rogue Data Cache Load, that they call 3a, but one that doesn't require mitigation).

The various fixes will get merged eventually in the kernels that are still supported ( 3.18, 4.4 and 4.9 - versions considered still supported by Google ). But it's very unlikely that there will be efforts to bring them to older kernels (like the 3.10 that Sailfish X is currently using).

It's starting to look very urgent for Jolla to move Sailfish X to the newest Sony kernel.

sailfish x 2.1.4

changelog mentions upgrade to kernel 3..10.108

My mistake, the correct package to check for is droid-hal-f5121-img-boot. Which is still the exact same 3.10.84 version, only a new release (a new recompile, with the options mentioned by Jolla such as BTRFS enabled)

So still not 4.4 (and thus as release note reports, no little.BIG-aware scheduler yet), yet) but at least the SD cards bugs should get fixed.fixed nor SD cards fixes either.

Let's hope 4.4 will be there for version 2.2.0
