pasemi_mac: Improve RX interrupt mitigation

pasemi_mac: Improve RX interrupt mitigation

Currently the receive side interrupts will go off on the reception of
a packet, NAPI will poll the ring and keep polling as long as there's
a decent amount of packets to receive.

This is less than optimal, especially for LRO where it's better if we
have a more substantial amount of packets to process at once, to get
the real LRO benefits.

So, set the count threshold to a higher value and use the timeout feature
that will give us an interrupt even if not enough packets have come in
to set off the count threshold.

This is a bit awkward. We don't have a timer-delayed interrupt on TX

regular timer that will take care of rotting packets for the last 1..31

16 years agoFix e100 on systems that have cache incoherent DMA
David Acker [Thu, 8 Nov 2007 18:17:41 +0000 (10:17 -0800)]
Fix e100 on systems that have cache incoherent DMA

On the systems that have cache incoherent DMA, including ARM, there
is a race condition between software allocating a new receive buffer
and hardware writing into a buffer.  The two race on touching the last
Receive Frame Descriptor (RFD).  It has its el-bit set and its next
link equal to 0.  When hardware encounters this buffer it attempts to
write data to it and then update Status Word bits and Actual Count in
the RFD.  At the same time software may try to clear the el-bit and
set the link address to a new buffer.

Since the entire RFD is once cache-line, the two write operations can
collide.  This can lead to the receive unit stalling or interpreting
random memory as its receive area.

The fix is to set the el-bit on and the size to 0 on the next to last
buffer in the chain.  When the hardware encounters this buffer it stops
and does not write to it at all.  The hardware issues an RNR interrupt
with the receive unit in the No Resources state.  Software can write
to the tail of the list because it knows hardware will stop on the
previous descriptor that was marked as the end of list.

Once it has a new next to last buffer prepared, it can clear the el-bit
and set the size on the previous one.  The race on this buffer is safe
since the link already points to a valid next buffer and the software
can handle the race setting the size (assuming aligned 16 bit writes
are atomic with respect to the DMA read). If the hardware sees the
el-bit cleared without the size set, it will move on to the next buffer
and skip this one.  If it sees the size set but the el-bit still set,
it will complete that buffer and then RNR interrupt and wait.

While cleaning up the internal API focussing on Fiber and CX4 code
we found that I had broken the copper PHY initialization code. This
patch restores the PHY-specific code. This is mostly uninteresting
since no copper PHY boards are yet available. The changes have been
tested against Fiber only as I do not even have copper PHY versions
of 82598 macs.

This change actually cleans up the API code a bit more and we
lose some initialization code. A few PHY link detection helper
lines of code have been snuck into this patch, as well as a

correctly on any of the chipsets that have 82573 on mobile platforms

 - eeprom reads return garbage information leading to bad eeprom

 - complete system hangs (freeze/lockup)

solutions also suffer from these symptoms.

Disabling L1 ASPM before we activate the PCI-E link fixes all of
these issues at the cost of some power consumption.
