This patch adds support\nfor multiple switch chips on a network interface.\n\nAn example topology for a 16-port device with an embedded CPU is as\nfollows:\n\n\t+-----+ +--------+ +--------+\n\t| |eth0 10| switch |9 10| switch |\n\t| CPU +----------+ +-------+ |\n\t| | | chip 0 | | chip 1 |\n\t+-----+ +---++---+ +---++---+\n\t || ||\n\t || ||\n\t ||1000baseT ||1000baseT\n\t ||ports 1-8 ||ports 9-16\n\nThis requires a couple of interdependent changes in the DSA layer:\n\n- The dsa platform driver data needs to be extended: there is still\n only one netdevice per DSA driver instance (eth0 in the example\n above), but each of the switch chips in the tree needs its own\n mii_bus device pointer, MII management bus address, and port name\n array. (include/net/dsa.h) The existing in-tree dsa users need\n some small changes to deal with this. (arch/arm)\n\n- The DSA and Ethertype DSA tagging modules need to be extended to\n use the DSA device ID field on receive and demultiplex the packet\n accordingly, and fill in the DSA device ID field on transmit\n according to which switch chip the packet is heading to.\n (net/dsa/tag_{dsa,edsa}.c)\n\n- The concept of \"CPU port\", which is the switch chip port that the\n CPU is connected to (port 10 on switch chip 0 in the example), needs\n to be extended with the concept of \"upstream port\", which is the\n port on the switch chip that will bring us one hop closer to the CPU\n (port 10 for both switch chips in the example above).\n\n- The dsa platform data needs to specify which ports on which switch\n chips are links to other switch chips, so that we can enable DSA\n tagging mode on them. (For inter-switch links, we always use\n non-EtherType DSA tagging, since it has lower overhead. The CPU\n link uses dsa or edsa tagging depending on what the \u0027root\u0027 switch\n chip supports.) This is done by specifying \"dsa\" for the given\n port in the port array.\n\n- The dsa platform data needs to be extended with information on via\n which port to reach any given switch chip from any given switch chip.\n This info is specified via the per-switch chip data struct -\u003ertable[]\n array, which gives the nexthop ports for each of the other switches\n in the tree.\n\nFor the example topology above, the dsa platform data would look\nsomething like this:\n\n\tstatic struct dsa_chip_data sw[2] \u003d {\n\t\t{\n\t\t\t.mii_bus\t\u003d \u0026foo,\n\t\t\t.sw_addr\t\u003d 1,\n\t\t\t.port_names[0]\t\u003d \"p1\",\n\t\t\t.port_names[1]\t\u003d \"p2\",\n\t\t\t.port_names[2]\t\u003d \"p3\",\n\t\t\t.port_names[3]\t\u003d \"p4\",\n\t\t\t.port_names[4]\t\u003d \"p5\",\n\t\t\t.port_names[5]\t\u003d \"p6\",\n\t\t\t.port_names[6]\t\u003d \"p7\",\n\t\t\t.port_names[7]\t\u003d \"p8\",\n\t\t\t.port_names[9]\t\u003d \"dsa\",\n\t\t\t.port_names[10]\t\u003d \"cpu\",\n\t\t\t.rtable\t\t\u003d (s8 []){ -1, 9, },\n\t\t}, {\n\t\t\t.mii_bus\t\u003d \u0026foo,\n\t\t\t.sw_addr\t\u003d 2,\n\t\t\t.port_names[0]\t\u003d \"p9\",\n\t\t\t.port_names[1]\t\u003d \"p10\",\n\t\t\t.port_names[2]\t\u003d \"p11\",\n\t\t\t.port_names[3]\t\u003d \"p12\",\n\t\t\t.port_names[4]\t\u003d \"p13\",\n\t\t\t.port_names[5]\t\u003d \"p14\",\n\t\t\t.port_names[6]\t\u003d \"p15\",\n\t\t\t.port_names[7]\t\u003d \"p16\",\n\t\t\t.port_names[10]\t\u003d \"dsa\",\n\t\t\t.rtable\t\t\u003d (s8 []){ 10, -1, },\n\t\t},\n\t},\n\n\tstatic struct dsa_platform_data pd \u003d {\n\t\t.netdev\t\t\u003d \u0026foo,\n\t\t.nr_switches\t\u003d 2,\n\t\t.sw\t\t\u003d sw,\n\t};\n\nSigned-off-by: Lennert Buytenhek \u003cbuytenh@marvell.com\u003e\nTested-by: Gary Thomas \u003cgary@mlbassoc.com\u003e\nSigned-off-by: David S.

Let\u0027s consider a scenario where we have\ntwo PPP links making up a bundle: a slow link (10KB/sec) and a fast\nlink (1000KB/sec) working at the best (full bandwidth). On the top we\nhave a TCP/IP stack sending a 1000 Bytes sk_buff buffer down to the\nPPP subsystem. The \"ppp_mp_explode\" function will divide the buffer in\ntwo fragments of 500B each (we are neglecting all the headers, crc,\nflags etc?.). Before the TCP/IP stack sends out the next buffer, it\nwill have to wait for the ACK response from the remote peer, so it\nwill have to wait for both fragments to have been sent over the two\nPPP links, received by the remote peer and reconstructed. The\nresulting behaviour is that, rather than having a bundle working\n@1010KB/sec (the sum of the channels bandwidths), we\u0027ll have a bundle\nworking @20KB/sec (the double of the slowest channels bandwidth).\n\n\nProblem Solution:\n\nThe problem has been solved by redesigning the \"ppp_mp_explode\"\nfunction in such a way to make it split the sk_buff buffer according\nto the speeds of the underlying PPP channels (the speeds of the serial\ninterfaces respectively attached to the PPP channels). Referring to\nthe above example, the redesigned \"ppp_mp_explode\" function will now\ndivide the 1000 Bytes buffer into two fragments whose sizes are set\naccording to the speeds of the channels where they are going to be\nsent on (e.g . 10 Byets on 10KB/sec channel and 990 Bytes on\n1000KB/sec channel). The reworked function grants the same\nperformances of the original one in optimal working conditions (i.e. a\nbundle made up of PPP links all working at the same speed), while\ngreatly improving performances on the bundles made up of channels\nworking at different speeds.\n\nSigned-off-by: Gabriele Paoloni \u003cgabriele.paoloni@intel.com\u003e\nSigned-off-by: David S.

As a first rough\nversion, it actually stops the AC queue for extended periods of time,\nwhich can be removed by adding buffering internal to mac80211, but is\ncurrently not a huge problem because people rarely use multiple TIDs\nthat are in the same AC (and iwlwifi currently doesn\u0027t operate as AP).\n\nThis is a short-term fix, my current medium-term plan, which I hope to\nexecute soon as well, but am not sure can finish before .30, looks like\nthis:\n 1) rework the internal queuing layer in mac80211 that we use for\n fragments if the driver stopped queue in the middle of a fragmented\n frame to be able to queue more frames at once (rather than just a\n single frame with its fragments)\n 2) instead of stopping the entire AC queue, queue up the frames in a\n per-station/per-TID queue during aggregation session initiation,\n when the session has come up take all those frames and put them\n onto the queue from 1)\n 3) push the ampdu queue layer abstraction this patch introduces in\n mac80211 into the driver, and remove the virtual queue stuff from\n mac80211 again\n\nThis plan will probably also affect ath9k in that mac80211 queues the\nframes instead of passing them down, even when there are no ampdu queues.\n\nSigned-off-by: Johannes Berg \u003cjohannes@sipsolutions.net\u003e\nSigned-off-by: John W.

So only in the\ncase where the L2CAP channel with the disconnect reason is really the\nlast one, it will propagated to the HCI layer.\n\nThe HCI layer has been extended with a disconnect indication that allows\nit to ask upper layers for a disconnect reason. The upper layer must not\nsupport this callback and in that case it will nicely default to the\nexisting behavior. If an upper layer like L2CAP can provide a disconnect\nreason that one will be used to disconnect the ACL or SCO link.\n\nNo modification to the ACL disconnect timeout have been made. So in case\nof Linux to Linux connection the initiator will disconnect the ACL link\nbefore the acceptor side can signal the specific disconnect reason. That\nis perfectly fine since Linux doesn\u0027t make use of this value anyway. The\nL2CAP layer has a perfect valid error code for rejecting connection due\nto a security violation. It is unclear why the Bluetooth specification\ninsists on having specific HCI disconnect reason.\n\nSigned-off-by: Marcel Holtmann \u003cmarcel@holtmann.org\u003e\n" }, { "commit": "f29972de8e7476706ab3c01304a505e7c95d9040", "tree": "966729f6b80d0e149b0ece4367d27f52306cc8cb", "parents": [ "e1027a7c69700301d14db03d2e049ee60c4f92df" ], "author": { "name": "Marcel Holtmann", "email": "marcel@holtmann.org", "time": "Thu Feb 12 05:07:45 2009 +0100" }, "committer": { "name": "Marcel Holtmann", "email": "marcel@holtmann.org", "time": "Fri Feb 27 06:14:42 2009 +0100" }, "message": "Bluetooth: Add CID field to L2CAP socket address structure\n\nIn preparation for L2CAP fixed channel support, the CID value of a\nL2CAP connection needs to be accessible via the socket interface.

Although rcuclassic and rcutree can also use this\nsame optimization after boot completes, rcupreempt must restrict its\nuse of this optimization to the portion of the boot sequence before the\nscheduler starts up, given that an rcupreempt RCU read-side critical\nsection may be preeempted.\n\nIn addition, this patch takes Nick Piggin\u0027s suggestion to make the\nsystem_state global variable be __read_mostly.\n\nChanges since v4:\n\no\tChanges the name of the introduced function and variable to\n\tbe less emotional. ;-)\n\nChanges since v3:\n\no\tWARN_ON(nr_context_switches() \u003e 0) to verify that RCU\n\tswitches out of boot-time mode before the first context\n\tswitch, as suggested by Nick Piggin.\n\nChanges since v2:\n\no\tCreated rcu_blocking_is_gp() internal-to-RCU API that\n\tdetermines whether a call to synchronize_rcu() is itself\n\ta grace period.\n\no\tThe definition of rcu_blocking_is_gp() for rcuclassic and\n\trcutree checks to see if but a single CPU is online.\n\no\tThe definition of rcu_blocking_is_gp() for rcupreempt\n\tchecks to see both if but a single CPU is online and if\n\tthe system is still in early boot.\n\n\tThis allows rcupreempt to again work correctly if running\n\ton a single CPU after booting is complete.\n\no\tAdded check to rcupreempt\u0027s synchronize_sched() for there\n\tbeing but one online CPU.\n\nTested all three variants both SMP and !SMP, booted fine, passed a short\nrcutorture test on both x86 and Power.\n\nLocated-by: Vegard Nossum \u003cvegard.nossum@gmail.com\u003e\nTested-by: Vegard Nossum \u003cvegard.nossum@gmail.com\u003e\nTested-by: Paul E.

However, this emulation is not perfect, as\nalso noticed on changeset 7500b1f602aad75901774a67a687ee985d85893f.\n\nBefore this patch, the kernel were trying to check if the serial TX is\ncapable of work using IRQ\u0027s.\n\nThis were done with a code similar this:\n\n serial_outp(up, UART_IER, UART_IER_THRI);\n lsr \u003d serial_in(up, UART_LSR);\n iir \u003d serial_in(up, UART_IIR);\n serial_outp(up, UART_IER, 0);\n\n if (lsr \u0026 UART_LSR_TEMT \u0026\u0026 iir \u0026 UART_IIR_NO_INT)\n\t\tup-\u003ebugs |\u003d UART_BUG_TXEN;\n\nThis works fine for other 8250 ports, but, on 8250-emulated SoL port, the\nchip is a little lazy to down UART_IIR_NO_INT at UART_IIR register.\n\nDue to that, UART_BUG_TXEN is sometimes enabled. However, as TX IRQ keeps\nworking, and the TX polling is now enabled, the driver miss-interprets the\nIRQ received later, hanging up the machine until a key is pressed at the\nserial console.\n\nThis is the 6 version of this patch. Previous versions were trying to\nintroduce a large enough delay between serial_outp and serial_in(up,\nUART_IIR), but not taking forever. However, the needed delay couldn\u0027t be\nsafely determined.\n\nAt the experimental tests, a delay of 1us solves most of the cases, but\nstill hangs sometimes. Increasing the delay to 5us was better, but still\ndoesn\u0027t solve. A very high delay of 50 ms seemed to work every time.\n\nHowever, poking around with delays and pray for it to be enough doesn\u0027t\nseem to be a good approach, even for a quirk.\n\nSo, instead of playing with random large arbitrary delays, let\u0027s just\ndisable UART_BUG_TXEN for all SoL ports.\n\n[akpm@linux-foundation.org: fix warnings]\nSigned-off-by: Mauro Carvalho Chehab \u003cmchehab@redhat.com\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" } ], "next": "01b24fee285b098c74318a8be801ef3711ec18d7" }
