linux.git/drivers/net/tile, branch v2.6.39 Linux kernel source tree tile on-chip network driver: sync up with latest fixes 2011-03-10T18:18:12+00:00 Chris Metcalf cmetcalf@tilera.com 2011-03-01T17:49:53+00:00 d91c641233ae09fcccec75313b7f55992668bf8d Combine the "command" and "completion" locks into a single lock, on each egress queue, to improve efficiency. Support the use of 4KB pages in the "egress queue". Delete the unused "duplicate ACK compression" code. Filter "bad" (i.e. truncated) packets. Avoid corrupting "dev->napi_list", by sequentializing modifications. Deregister for incoming packets during stop, to reduce unexpected interrupts. Also, encourage active NAPI loops to complete before we disable NAPI, which would otherwise crash. Free any pending completions after shutting down LEPP. Use a single, permanently registered, IRQ handler, to avoid situations in which the IRQ handler was firing after being freed, and ignore any "unexpected" interrupts. Drop egress packets, instead of spinning, if the hardware cannot keep up, or is disconnected. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com> 
Combine the "command" and "completion" locks into a single lock,

Deregister for incoming packets during stop, to reduce unexpected

we disable NAPI, which would otherwise crash.

Free any pending completions after shutting down LEPP.

Use a single, permanently registered, IRQ handler, to avoid situations
in which the IRQ handler was firing after being freed, and ignore any
"unexpected" interrupts.

Drop egress packets, instead of spinning, if the hardware cannot keep
up, or is disconnected.

arch/tile: enhance existing finv_buffer_remote() routine 2011-03-01T21:21:06+00:00 Chris Metcalf cmetcalf@tilera.com 2011-02-28T20:48:39+00:00 63b7ca6b04427aea9075d6f5f5f15b82e115bce4 It now takes an additional argument so it can be used to flush-and-invalidate pages that are cached using hash-for-home as well those that are cached with coherence point on a single cpu. This allows it to be used more widely for changing the coherence point of arbitrary pages when necessary. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com> 
It now takes an additional argument so it can be used to
flush-and-invalidate pages that are cached using hash-for-home
as well those that are cached with coherence point on a single cpu.

This allows it to be used more widely for changing the coherence
point of arbitrary pages when necessary.

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>
