For those that haven't been paying attention to the Phoronix articles in the prior weeks about the Linux 3.7 kernel, some of the new features to this kernel include:
- Improved power management for Radeon GPUs.
- Improved Intel graphics support for new hardware.
- The Nouveau DRM driver was largely reworked.
- Other Direct Rendering Manager changes.
- 64-bit ARM support a.k.a. ARMv8 / AArch64.
- ARM Xen virtualization support for the Cortex-A15.
- A single ARM Linux kernel now supports multiple devices.
- Nintendo Wii Balance Board driver support.
- Intel Supervisor Mode Access Prevention (SMAP) handling.
- Oracle SPARC-T4 processor support.
- New work within the staging tree.
- Audio Run-Time Power Management.
- JFS TRIM support when using the file-system on SSDs.
- EXT4 enhancements.
- Btrfs hole-punching and other new capabilities for the experimental file-system.
- The Intel AES-NI support is now faster by utilizing parallel AES-NI hardware pipelines.
- Support for loading firmware files directly rather than relying on udev.
- Xen EFI video mode support.
- IPv6 Netfilter improvements.
Besides the many Linux 3.7 articles on Phoronix, there's also a brief overview of key 3.7 features by subsystem on KernelNewbies.org.
In terms of the Linux 3.7 kernel benchmarks already conducted there is:
- A 12-Way Radeon Gallium3D graphics card comparison.
- Comparing the latest open-source Radeon driver code to AMD Catalyst.
- Linux 3.7 file-system benchmarks including EXT4, XFS, and Btrfs.
- Btrfs file-system tuning of mount options on the new kernel.
- Other Linux 3.7 kernel benchmarks.
While the Linux 3.7 kernel turned out quite nice, next up is the Linux 3.8 kernel and there's already a lot of new features in the pipeline.
