Phoronix: Qualcomm Rolls Out ~110k Lines Of New Kernel Code For Snapdragon 845 Display Support

Qualcomm in cooperation with Google developers and Rob Clark of Freedreno/MSM has sent out a set of kernel patches amounting to over 110,000 lines of new kernel code for the MSM DRM driver to bring-up display support for the SDM845...

That seems like a lot of code for that functionality.

They have their own equivalent of DAL/DC going in.

This is pretty amazing that Qualcomm is now attempting to upstream drivers for a lot of their hardware. Hopefully this starts a trend with other big commercial ARM SoC vendors, where we eventually get to the point where the upstream kernels can run unmodified on popular ARM devices (i.e. Android phones, tablets, etc).

Their own "DC"? How on earth is that acceptable?

Their own "DC"? How on earth is that acceptable?

Because DC is a driver (AMD) specific implementation just as Qualcomm's new code is? DC wasn't designed to be some universal driver display framework for all drivers.

My first thought was "what's the quality and structure of the code?"
Is it ready for inclusion or a big mess still?
Then i saw that it's only an request for review and that the goal is get this driver in shape over the next coming months.
The next coming months sounds pretty fast but only time will tell.

Anyone know if this also applies to the Snapdragon 835?

Where can I find a list of Android phones that are able to run the upstream kernel out of the box? (besides the Nexus phones)

There is a Chromebook with Snapdragon 845 in development, this is way Google is involved here. 96Boards from Linaro was a nice push for Qualcomm to star upstreaming 400, 600 and 800 series of SOCs. One can run upstream packages for Dragonboard 410c. Someone doing a Chromebook with Snapdragon 845 will push all of these efforts to the max. Also Qualcomm learned that in server market everything must be upstream (e.g. otherwise you cannot get RHEL support).

Qualcomm SOCS are becoming one of the best high-end upstream supported ones. Heck, you even get open source GPU driver.

That Chromebook is on a shopping list, but sadly it will take long time before it hits the market.
