				Theory of Operation

I. Board Compatibility

This device driver is designed for the Intel i82557 "Speedo3" chip, Intel's
single-chip fast Ethernet controller for PCI, as used on the Intel
EtherExpress Pro 100 adapter.

II. Board-specific settings

PCI bus devices are configured by the system at boot time, so no jumpers
need to be set on the board.  The system BIOS should be set to assign the
PCI INTA signal to an otherwise unused system IRQ line.  While it's
possible to share PCI interrupt lines, it negatively impacts performance and
only recent kernels support it.

III. Driver operation

IIIA. General
The Speedo3 is very similar to other Intel network chips, that is to say
"apparently designed on a different planet".  This chips retains the complex
Rx and Tx descriptors and multiple buffers pointers as previous chips, but
also has simplified Tx and Rx buffer modes.  This driver uses the "flexible"
Tx mode, but in a simplified lower-overhead manner: it associates only a
single buffer descriptor with each frame descriptor.

Despite the extra space overhead in each receive skbuff, the driver must use
the simplified Rx buffer mode to assure that only a single data buffer is
associated with each RxFD. The driver implements this by reserving space
for the Rx descriptor at the head of each Rx skbuff.

The Speedo-3 has receive and command unit base addresses that are added to
almost all descriptor pointers.  The driver sets these to zero, so that all
pointer fields are absolute addresses.

The System Control Block (SCB) of some previous Intel chips exists on the
chip in both PCI I/O and memory space.  This driver uses the I/O space
registers, but might switch to memory mapped mode to better support non-x86
processors.

IIIB. Transmit structure

The driver must use the complex Tx command+descriptor mode in order to
have a indirect pointer to the skbuff data section.  Each Tx command block
(TxCB) is associated with two immediately appended Tx Buffer Descriptor
(TxBD).  A fixed ring of these TxCB+TxBD pairs are kept as part of the
speedo_private data structure for each adapter instance.

The newer i82558 explicitly supports this structure, and can read the two
TxBDs in the same PCI burst as the TxCB.

This ring structure is used for all normal transmit packets, but the
transmit packet descriptors aren't long enough for most non-Tx commands such
as CmdConfigure.  This is complicated by the possibility that the chip has
already loaded the link address in the previous descriptor.  So for these
commands we convert the next free descriptor on the ring to a NoOp, and point
that descriptor's link to the complex command.

An additional complexity of these non-transmit commands are that they may be
added asynchronous to the normal transmit queue, so we disable interrupts
whenever the Tx descriptor ring is manipulated.

A notable aspect of these special configure commands is that they do
work with the normal Tx ring entry scavenge method.  The Tx ring scavenge
is done at interrupt time using the 'dirty_tx' index, and checking for the
command-complete bit.  While the setup frames may have the NoOp command on the
Tx ring marked as complete, but not have completed the setup command, this
is not a problem.  The tx_ring entry can be still safely reused, as the
tx_skbuff[] entry is always empty for config_cmd and mc_setup frames.

Commands may have bits set e.g. CmdSuspend in the command word to either
suspend or stop the transmit/command unit.  This driver always flags the last
command with CmdSuspend, erases the CmdSuspend in the previous command, and
then issues a CU_RESUME.
Note: Watch out for the potential race condition here: imagine
	erasing the previous suspend
		the chip processes the previous command
		the chip processes the final command, and suspends
	doing the CU_RESUME
		the chip processes the next-yet-valid post-final-command.
So blindly sending a CU_RESUME is only safe if we do it immediately after
after erasing the previous CmdSuspend, without the possibility of an
intervening delay.  Thus the resume command is always within the
interrupts-disabled region.  This is a timing dependence, but handling this
condition in a timing-independent way would considerably complicate the code.

Note: In previous generation Intel chips, restarting the command unit was a
notoriously slow process.  This is presumably no longer true.

IIIC. Receive structure

Because of the bus-master support on the Speedo3 this driver uses the new
SKBUFF_RX_COPYBREAK scheme, rather than a fixed intermediate receive buffer.
This scheme allocates full-sized skbuffs as receive buffers.  The value
SKBUFF_RX_COPYBREAK is used as the copying breakpoint: it is chosen to
trade-off the memory wasted by passing the full-sized skbuff to the queue
layer for all frames vs. the copying cost of copying a frame to a
correctly-sized skbuff.

For small frames the copying cost is negligible (esp. considering that we
are pre-loading the cache with immediately useful header information), so we
allocate a new, minimally-sized skbuff.  For large frames the copying cost
is non-trivial, and the larger copy might flush the cache of useful data, so
we pass up the skbuff the packet was received into.

IV. Notes

Thanks to Steve Williams of Intel for arranging the non-disclosure agreement
that stated that I could disclose the information.  But I still resent
having to sign an Intel NDA when I'm helping Intel sell their own product!

peanut butter does not require refrigeration; however refrigerating natural peanut butter will slow the oil separation.
the oil in natural butter will always separate and rise to the top because nothing has been added to prevent the separation; this is one reason why they are natural. always stir the oil back in. do not pour it off or else the product on the bottom of the container will be very hard.

Daniel Raymond Flynn (born 16 April 1985) is a New Zealand former cricketer who played for Northern Districts and has also represented the New Zealand international side. In April 2020, Flynn announced his retirement from cricket.

Domestic career
He has captained the New Zealand Under-19 side in Youth ODIs. He was educated at Tauranga Boys' College and was in the 1st XI from 1999 to 2002, being captain in his last two years.

Daniel is a resident of Tauranga, which is in the Bay of Plenty, New Zealand. This falls into the catchment area of the Northern Districts Cricket Association. He has played two seasons at Barnards Green Cricket Club in Worcestershire, England. Daniel holds the league record for runs scored in the Worcestershire League with a highest score of 184. In March 2011 Flynn joined Dunfermline Knights, Scotland, to play for the 2011 season.

In June 2018, he was awarded a contract with Northern Districts for the 2018–19 season. In November 2019, during the 2019–20 Plunket Shield season, Flynn played in his 100th first-class match.

International career
On 6 February 2008, Flynn took the place of the injured Jacob Oram for the second international Twenty20 against England, having impressed on 30 January, hitting 149 in a domestic match. New Zealand fell to a second defeat in the Twenty20 series, however, with Flynn surviving only two deliveries, making one run, before being dismissed by Graeme Swann. He then replaced an out-of-form Peter Fulton for the final One Day International on 23 February 2008. Flynn then accompanied the New Zealand team to England and, on 15 May 2008 made his test debut.

On 23 May, whilst batting at number 6 for New Zealand, against England, Flynn was hit in the grille by a rising ball from James Anderson. Flynn retired hurt and lost a tooth. It was also stated on TMS that more teeth were loosened and removed by a dentist later that day.

This is a worthy of the Chinese people to know, understand, study and remember of the artist.

Two battles in 1934 anti-japanese fallen monument ', 1939 'Wang Mingzhang riding like' Li Jiayu horse statue, in 1944 the sun yat-sen's bronze statue and so on, are the representative work of early Liu Kaiqu, intended to arouse the Chinese people's revolutionary enthusiasm and morale. Completed in 1945 of a large high relief 'a&m's home', more could be seen as a artist in drift from place to place in the life for yourself, for the masses to shape the new shangri-la. This is the first in the history of Chinese figurines to ordinary workers image for the leading role of work. At first, Liu Kaiqu hope will be a performance of workers and peasants labor scene embossed positioned below the 'sun yat-sen's bronze statue, eventually because of the limited budget to do it. The idea in his mind for a long time, finally presents a high 333 cm, 140 cm wide, a&m's home.

Three Thunder Players Who Need to Make a Statement In Friday's Game vs. the Bulls
Posted bybencreider December 18, 2020 December 1, 2021 Posted inOpinion
With the final preseason game approaching, people should remember that the Thunder still stands way over the maximum threshold for players on the roster (15.) Currently, the Thunder have 20 players on their roster, with 18 of those being on full-scale NBA contracts. Three roster spots need to be shed and for alot of players and some difficult decisions will have to be made.
Here are Three Thunder Players Who Need to Make a Statement in Friday's game:
Admiral Schofield- SG/SF

Schofield has been on my safe list since he was traded to the Thunder last month, but his lack of production in the preseason will definitely put a magnifying glass on how he is able to finish things off in the Thunder's final game vs. the Bulls.
Admiral Schofield's Stats Thus Far- 13.0 MPG, 0% FG (0-3), 1 APG, 1 RPG
Schofield really has not made any sort of impact in either game, but there's a valid case that he was not given a real opportunity to shine in either game. His minutes were all in the second half of games and in the case of Wednesday's game vs. the Bulls, he just played garbage time minutes in the 4th.
Schofield, is a 6'5″ Shooting Guard who came into the NBA weighing in at 241 lbs. There have been reports that Schofield has cut down as much as 15 pounds heading into the offseason, but he still looks very big. Schofield's bread and butter thus far in his career has been with catch and shooting ability, as well as his sneaky good athleticism he possesses around the basket.
I'd expect Schofield to be playing 20+ minutes tonight as he has hardly had any run with the team and hasn't been very productive in his minutes.
Justin Jackson – SF/PF

Justin Jackson did not have a good debut with the Thunder on Wednesday. Jackson shot 3/11, with most of his shots being heavily contested runners, which to no ones surprise fell short. He played at the 3 and 4 positions, but his speed and athleticism really limits himself to being a Power Forward.
He's more of a one trick pony as he's been coined a straight shooter since being drafted into the NBA, and the same still applies now. The role of him spotting up in the corner is where he is best suited at, and if he is able to string together a nice game from distance it may just be enough for the coaches to want to see him more in the regular season.
T.J. Leaf – PF/C

T.J. Leaf was brought into the Thunder organization just a few weeks ago as we dealt off Jalen Lecque for him and a future 2nd. Just like Justin Jackson, T.J. Leaf is more of your standard stretch four, but his size at 6'10" allows him to also play at the center position.
Leaf did not play in Wednesday's gave vs. the Bulls, but he has been cleared to play in Friday's game vs. the Bulls. He was 2-5 in his one game thus far against the Spurs, but he actually racked up a solid statline with 8/5/0 in 17 minutes.
He is really in the same boat as Justin Jackson, fighting over who will be playing in the second unit alongside Mike Muscala in the frontcourt.
Could there be a dynamic duo brewing between Theo Maledon and Isaiah Roby?

100 Creatives: Andy Noble

Troy Schulze | March 8, 2011 | 9:00am
(Part of our ongoing series profiling 100 Houston-area artists. No rankings; no order. Check back every Tuesday and Thursday for another edition.)
What he does: "I have a hip-hop background," says Andy Noble, co-founder of Noble Motion Dance, "and that's how I came to dance. I started off as a breakdancer." With his wife Dionne Sparkman Noble, Andy has built a company of diverse backgrounds and influence that approaches modern dance from a unique perspective, free from rigid training regimens like ballet, and with a lean toward theater and film. "Both my wife and I have studied dance and technology," says Noble, "we've made filmwork before. We're not afraid to incorporate technology into our work." Noble considers himself a director as much as a choreographer, and he incorporates character, plot and spectacle, in addition to movement and shape, into his dance pieces.
Why he likes it: The 36 year-old enjoys the collaborative nature of dance. "I really love working with dancers, my wife and other collaborators," says Noble. "For me that's the most important part of the work. If you enjoy the people you're working with then the product is enjoyable." Noble also enjoys the potential to influence others. "This might sound cheesy, but I think art can make a difference," he says. "It may not change people's life decisions, but maybe they go home and they're nicer to their husband or their wife for a moment, and maybe that helps a little bit. I'm not under the belief that I can change the world with my work, but maybe I can make it a little bit better."
What inspires him: Besides being inspired by colleagues and collaborators, Noble gets ideas from artwork of all kinds, especially film. In the Bedroom, Fight Club and Where the Wild Things Are have all inspired specific works. "Quite often I'll see images in films that I'll incorporate. I also watch how the actors use their bodies to communicate and how it's framed," he says.
If not this, what? If Noble wasn't a choreographer, he imagines he'd be working in film or theater. "The reason I didn't go [the theater] route was that the family was all doing that," says Noble, whose parents and family have a theater background. "My way of rebelling was being a dancer."
