linux kernel map

Among others, the new kernel includes 3D support in the GPU driver,
allowing 3D hardware-accelerated graphics inside virtual machines,
support for Open-Channel SSDs via LightNVM has been added,
journaled RAID5 MD support has been implemented and various driver updates and fixes
have been included as well.
Linux 4.4 is currently around 20.8 million lines or an increase of about 200 thousand lines
of code/documentation and a few hundred new files after Linus accepted around 12,000 commits for this merge window.

Install the Kernel:

$ sudo dpkg -i linux-headers-4.4*.deb linux-image-4.4*.deb

Install in 64bit systems Ubuntu and derivative systems:

 

$ cd /tmp

Install the Kernel:

$ sudo dpkg -i linux-headers-4.4*.deb linux-image-4.4*.deb


Optional, remove the kernel:(Better to remove after restart and check if the system work properly)

 

$ sudo apt-get remove linux-headers-4.4* linux-image-4.4*

 

Graphics

  • AMD Stoney support, initial graphics support for an upcoming AMD APU launch.
  • There are numerous AMDGPU additions for those with an AMD Carrizo, Tonga, or Fiji graphics processor. That includes enabling the AMDGPU scheduler by default, new AtomBIOS opcodes, and various fixes. Sadly, there isn't any power management support in AMDGPU for Linux 4.4 for the discrete graphics cards, but those PowerPlay patches are coming for Linux 4.5 to significantly boost the performance of this modern open-source driver.
  • There's a Raspberry Pi KMS driver that's finally landed after the extensive work done by Eric Anholt at Broadcom. Unfortunately for Linux 4.4, this Raspberry Pi kernel graphics driver is just for kernel mode-setting and doesn't yet handle 3D hardware acceleration or power management. Eric is still working on that acceleration code as well as the accompanying VC4 Gallium3D driver.
  • We finally have the VirtIO VirGL DRM code! This is used in conjunction with the VirtIO VirGL code in Mesa's Gallium3D along with changes in QEMU 2.5 for providing OpenGL acceleration support to guest virtual machines over QEMU+KVM with VirtIO. VMWare and VirtualBox have long offered 3D acceleration to guest VMs and it's great that finally there is support on a fully open-source virtualization stack. Of course, it will be a while before the necessary Mesa and QEMU code trickles down in released form to distributions.
  • Nouveau has some re-clocking improvements, better stability, and other enhancements but nothing too jaw-dropping. There's still no hardware acceleration for the modern GeForce GTX 900 series as NVIDIA hasn't yet supplied the developers with the needed signed firmware images.
  • Freedreno's MSM driver has added Snapdragon 820 support as Qualcomm's newest SoC.
  • The Intel DRM code in Linux 4.4 is primarily about fixes and other low-level improvements. The primary benefactors of Intel's latest work continues to be Skylake and Broxton graphics hardware.
  • Core DRM code includes more atomic mode-setting work and other changes.
