linux-stable.git/arch/tile/include/hv/netio_errors.h, branch master Linux kernel stable tree arch: remove tile port 2018-03-16T09:56:03+00:00 Arnd Bergmann arnd@arndb.de 2018-03-09T13:13:42+00:00 bb9d812643d8a121df7d614a2b9c60193a92deb0 The Tile architecture port was added by Chris Metcalf in 2010, and maintained until early 2018 when he orphaned it due to his departure from Mellanox, and nobody else stepped up to maintain it. The product line is still around in the form of the BlueField SoC, but no longer uses the Tile architecture. There are also still products for sale with Tile-GX SoCs, notably the Mikrotik CCR router family. The products all use old (linux-3.3) kernels with lots of patches and won't be upgraded by their manufacturers. There have been efforts to port both OpenWRT and Debian to these, but both projects have stalled and are very unlikely to be continued in the future. Given that we are reasonably sure that nobody is still using the port with an upstream kernel any more, it seems better to remove it now while the port is in a good shape than to let it bitrot for a few years first.

The Tile architecture port was added by Chris Metcalf in 2010, and
maintained until early 2018 when he orphaned it due to his departure
from Mellanox, and nobody else stepped up to maintain it. The product
line is still around in the form of the BlueField SoC, but no longer
uses the Tile architecture.

There are also still products for sale with Tile-GX SoCs, notably the
Mikrotik CCR router family. The products all use old (linux-3.3) kernels
with lots of patches and won't be upgraded by their manufacturers. There
have been efforts to port both OpenWRT and Debian to these, but both
projects have stalled and are very unlikely to be continued in the future.

Given that we are reasonably sure that nobody is still using the port
with an upstream kernel any more, it seems better to remove it now while
the port is in a good shape than to let it bitrot for a few years first.

drivers/net/tile/: on-chip network drivers for the tile architecture 2010-11-24T18:11:18+00:00 Chris Metcalf cmetcalf@tilera.com 2010-11-01T21:00:37+00:00 e5a06939736277c54a68ae275433db55b99d187c This change adds the first network driver for the tile architecture, supporting the on-chip XGBE and GBE shims. The infrastructure is present for the TILE-Gx networking drivers (another three source files in the new directory) but for now the the actual tilegx sources are waiting on releasing hardware to initial customers. Note that arch/tile/include/hv/* are "upstream" headers from the Tilera hypervisor and will probably benefit less from LKML review. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
