UART is then working only as plain 16450 without FIFOs. On\nsystems with higher interrupt latency this causes buffer overruns and\nloss of received data when using higher communication speeds.\n\nI\u0027m working for a company which produces industrial computers. These\ndevices typically contain high number (8 or more) of traditional 16550A\nuarts - we use TL16C554A chips, but that is not much relevant. UARTs are\nconnected to the CPU by ISA bus (Celeron based devices) or LPC bus (Atom\nbased devices).\n\nIn the Linux the UARTs are using standard 8250.c driver and are\ninitialized using setserial command:\nsetserial /dev/ttyS4 uart 16550A port 0x3E0 irq 10 baud_base 115200\n\nThis executes the UART initialization through serial8250_startup()\nfunction. At the beginning of the function up-\u003ecapabilities is\ninitialized from uart_config:\n up-\u003ecapabilities \u003d uart_config[up-\u003eport.type].flags;\nPlease note that neither up-\u003eport.fifosize nor up-\u003etx_loadsz is\ninitialized here!!\n\nLater in the same function serial8250_clear_fifos() is called and\ndisables FIFOs. The above comment says that they will be reenabled in\nset_termios (they won\u0027t ...)\n\nAfter serial8250_startup() the serial8250_set_termios() is called. In\nthis function the following check fails because up-\u003eport.fifosize is\nzero because it is not initialized correctly.\n\n if (up-\u003ecapabilities \u0026 UART_CAP_FIFO \u0026\u0026 up-\u003eport.fifosize \u003e 1) {\n if (baud \u003c 2400)\n fcr \u003d UART_FCR_ENABLE_FIFO | UART_FCR_TRIGGER_1;\n else\n fcr \u003d uart_config[up-\u003eport.type].fcr;\n }\n\nfcr variable remains zero and in the end the FCR register is set to zero\nwhich results in disabled FIFOs even if the UART type is 16550A. This is\nalso true for other types of UARTs with FIFOs.\n\nIf the UART is autoconfigured via \u0027setserial /dev/ttySx autoconfig\u0027 then\nport.fifosize and tx_loadsz are initialized correctly in the\nautoconfig() function and the UART is working correctly then.\n\nI checked the source codes and I can say that this bug is present in\n2.6.x series of kernels for a couple of years. Namely I can confirm its\npresence in 2.6.16.57, 2.6.32.24 and 2.6.36.1 (tested all of them on our\nhardware).\n\nI think it was not noticed before because not many people use manually\nconfigured non PNP UARTs on ISA/LPC bus these days. Also the data loss\ncaused by buffer overruns occures only if IRQ latency is higher then\ntime needed to receive one character on given communication speed.\nFor example our hardware looses received characters only if the UARTs\nare connected throught LPC bus with SERIRQ (serial IRQ transport) and\nnot if they are connected to ISA bus because LPC SERIRQ has higher\ninterrupt latency then parallel ISA interupt lines.\n\nHere is the patch to correct the bug created against 2.6.36.1:\n\nSigned-off-by: Ondrej Puzman \u003cpuzman@gmail.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n" }, { "commit": "a3ae0fc34f58e7163b7724feb3d77aa4603f0dc3", "tree": "05c435ba0ee0b071e3c45bcef33eac9f1fd37e80", "parents": [ "49d5741be27aa90301b89bf254972b355ed9c8ee" ], "author": { "name": "Jamie Iles", "email": "jamie@jamieiles.com", "time": "Wed Dec 01 23:39:36 2010 +0000" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Fri Dec 10 15:19:38 2010 -0800" }, "message": "8250: add a UPIO_DWAPB32 for 32 bit accesses\n\nSome platforms contain a Synopsys DesignWare APB UART that is attached\nto a 32-bit APB bus where sub-word accesses are not allowed.

Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros.

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" }, { "commit": "125c97d8a59888c5678734c2b70cbd08c847bd99", "tree": "39a22727dbbf543d457d73c91cc9b6b9db164f8e", "parents": [ "e0b325d310a6b11f1538413fd557d2eb98f2fae5" ], "author": { "name": "Helge Deller", "email": "deller@gmx.de", "time": "Tue Jan 13 22:51:07 2009 +0100" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jan 13 14:03:43 2009 -0800" }, "message": "fix early_serial_setup() regression\n\nCommit b430428a188e8a434325e251d0704af4b88b4711 (\"8250: Don\u0027t clobber\nspinlocks.\") introduced a regression on the parisc architecture, which\nbroke the handover to the serial port at boottime.\n\nearly_serial_setup() was changed to only copy a subset of the uart_port\nfields, and sadly the \"type\" and \"line\" fields were forgotten and thus\nthe serial port was not initialized and could not be used for a\nhandover.

This fix saves the value of the LCR and\n rewrites it after clearing the interrupt.\n\n3 Workaround for interrupt/data concurrency issue: The SoC needs to\n ensure that writes that can cause interrupts to be cleared reach the UART\n before returning from the ISR. This fix reads a non-destructive register\n on the UART so the read transaction completion ensures the previously\n queued write transaction has also completed.\n\nSigned-off-by: Marc St-Jean \u003cMarc_St-Jean@pmc-sierra.com\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nCc: Ralf Baechle \u003cralf@linux-mips.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "4bf3631cdb012591667ab927fcd7719d92837833", "tree": "25976c75042f3aa557a7bc8ece781ea4901acc62", "parents": [ "c5408b88ecb8b7127334a34c55d4e0174434f4ec" ], "author": { "name": "Jiri Kosina", "email": "jkosina@suse.cz", "time": "Mon Apr 23 14:41:21 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Apr 24 08:23:09 2007 -0700" }, "message": "8250: fix possible deadlock between serial8250_handle_port() and serial8250_interrupt()\n\nCommit 40b36daa introduced possibility that serial8250_backup_timeout() -\u003e\nserial8250_handle_port() locks port.lock without disabling irqs, thus\nallowing deadlock against interrupt handler (port.lock is acquired in\nserial8250_interrupt()).\n\nSpotted by lockdep.\n\nSigned-off-by: Jiri Kosina \u003cjkosina@suse.cz\u003e\nCc: Dave Jones \u003cdavej@codemonkey.org.uk\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nCc: Alex Williamson \u003calex.williamson@hp.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "fdc30b3d448bf86dd45f9df3e8ac0d36a3bdd9b2", "tree": "e434f6c805916d51f288d2e4848a5e86b374edc1", "parents": [ "650a7c974f1b91de9732c0f720e792837f8abfd6" ], "author": { "name": "Taku Izumi", "email": "izumi2005@soft.fujitsu.com", "time": "Mon Apr 23 14:41:00 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Apr 24 08:23:07 2007 -0700" }, "message": "Fix possible NULL pointer access in 8250 serial driver\n\nI encountered the following kernel panic.

The problem is that the UART does not reassert the THRE interrupt\nif it has been previously cleared and the IIR THRI bit is re-enabled. This\ncan produce a very annoying failure mode when used as a serial console,\nallowing a boot/reboot to hang indefinitely until an RX interrupt kicks it\ninto working again (ie. an unattended reboot could stall).\n\nTo solve this problem, a backup timer is introduced that runs alongside the\nstandard interrupt driven mechanism. This timer wakes up periodically,\nchecks for a hang condition and gets characters moving again. This backup\nmechanism is only enabled if the UART is detected as having this problem,\nso systems without these UARTs will have no additional overhead.\n\nThis version of the patch incorporates previous comments from Pavel and\nremoves races in the bug detection code. The test is now done before the\nirq linking to prevent races with interrupt handler clearing the THRE\ninterrupt. Short delays and syncs are also added to ensure the device is\nable to update register state before the result is tested.\n\nAristeu says:\n\n this was tested on the following HP machines and solved the problem:\n rx2600, rx2620, rx1600 and rx1620s.\n\nhpa says:\n\n I have seen this same bug in soft UART IP from \"a major vendor.\"\n\nSigned-off-by: Alex Williamson \u003calex.williamson@hp.com\u003e\nCc: \"H.

On the FRV arch, removing the regs parameter\nfrom all the genirq function results in a 20% speed up of the IRQ exit path\n(ie: from leaving timer_interrupt() to leaving do_IRQ()).\n\nWhere appropriate, an arch may override the generic storage facility and do\nsomething different with the variable.

Consider a USB character\ndevice attached to a USB hub, attached to a USB controller that posts its\ninterrupts through a cascaded auxiliary interrupt controller.
