Eliminate 1 XX_VirtToPhys() and 2 XX_PhysToVirt() calls from if_dtsec(4) XX_VirtToPhys(), by way of pmap_kextract(), is an expensive operation. Profiling via dtrace during a series of iperf tests I found 16111 / 30432 stack frames were located in mmu_booke_kextract(), so eliminating this expensive call should improve performance slightly. XX_PhysToVirt() is not as expensive, but redundant calls in this context is wasteful.

Make DPAA work in 64-bit mode Rework the dTSEC and FMan drivers to be more like a full bus relationship, so that dtsec can use bus_alloc_resource() instead of trying to handle the offset from the dts. This required taking some code from the sparc64 ebus driver to allow subdividing the fman region for the dTSEC devices.

Update DPAA SDK to SDK 2.0 This adds some support for ARM as well as 64-bit. 64-bit on PowerPC is currently not working, and ARM support has not been completed or tested on the FreeBSD side. As this was imported from a Linux tree, it includes some Linux-isms (ioread/iowrite), so compile with the LinuxKPI for now. This may change in the future.

Shorten list of arguments to mbuf external storage freeing function. All of these arguments are stored in m_ext, so there is no reason to pass them in the argument list. Not all functions need the second argument, some don't even need the first one. The second argument lives in next cache line, so not dereferencing it is a performance gain. This was discovered in sendfile(2), which will be covered by next commits. The second goal of this commit is to bring even more flexibility to m_ext mbufs, allowing to create more fields in m_ext, opaque to the generic mbuf code, and potentially set and dereferenced by subsystems.

Simplify the page tracking for VA<->PA translations. Drop the tracking down to the pmap layer, with optimizations to only track necessary pages. This should give a (slight) performance improvement, as well as a stability improvement, as the tracking is already mostly handled by the pmap layer.

Make dpaa work with only slightly modified Linux device trees. Linux has a slightly different device tree definition for DPAA than originally done in the FreeBSD driver. This changes the driver to be mostly compatible with the Linux device tree definitions. Currently the differences are: bman-portals: compatible = "fsl,bman-portals" (Linux is "simple-bus") qman-portals: compatible = "fsl,qman-portals" (Linux is "simple-bus") fman: compatible = "fsl,fman" (Linux is "simple-bus") The Linux device tree doesn't specify anything for rgmii in the mdio. This change still requires the device tree to specify the phy-handle, and doesn't yet support tbi.

Add support for the Freescale dTSEC DPAA-based ethernet controller. Freescale's QorIQ line includes a new ethernet controller, based on their Datapath Acceleration Architecture (DPAA). This uses a combination of a Frame manager, Buffer manager, and Queue manager to improve performance across all interfaces by being able to pass data directly between hardware acceleration interfaces. As part of this import, Freescale's Netcomm Software (ncsw) driver is imported. This was an attempt by Freescale to create an OS-agnostic sub-driver for managing the hardware, using shims to interface to the OS-specific APIs. This work was abandoned, and Freescale's primary work is in the Linux driver (dual BSD/GPL license). Hence, this was imported directly to sys/contrib, rather than going through the vendor area. Going forward, FreeBSD-specific changes may be made to the ncsw code, diverging from the upstream in potentially incompatible ways. An alternative could be to import the Linux driver itself, using the linuxKPI layer, as that would maintain parity with the vendor-maintained driver. However, the Linux driver has not been evaluated for reliability yet, and may have issues with the import, whereas the ncsw-based driver in this commit was completed by Semihalf 4 years ago, and is very stable. Other SoC modules based on DPAA, which could be added in the future: * Security and Encryption engine (SEC4.x, SEC5.x) * RAID engine Additional work to be done: * Implement polling mode * Test vlan support * Add support for the Pattern Matching Engine, which can do regular expression matching on packets. This driver has been tested on the P5020 QorIQ SoC. Others listed in the dtsec(4) manual page are expected to work as the same DPAA engine is included in all.
