This\ncopying however has some bugs, like not wrapping the head counter. Since\nthis write queue is also a circular buffer, the consumer function is\nready to use the uart_core circular buffer directly.\n\nThis buggy copying function was making some bytes be dropped when\ntransmitting to a raw tty, doing something like this.\n\n[root@hostname ~]$ cat /dev/ttyn1 \u003e cascardo/dump \u0026\n[1] 2658\n[root@hostname ~]$ cat /proc/tty/drivers \u003e /dev/ttyn0\n[root@hostname ~]$ cat /proc/tty/drivers\n/dev/tty /dev/tty 5 0 system:/dev/tty\n/dev/console /dev/console 5 1 system:console\n/dev/ptmx /dev/ptmx 5 2 system\n/dev/vc/0 /dev/vc/0 4 0 system:vtmaster\njsm /dev/ttyn 250 0-31 serial\nserial /dev/ttyS 4 64-95 serial\nhvc /dev/hvc 229 0-7 system\npty_slave /dev/pts 136 0-1048575 pty:slave\npty_master /dev/ptm 128 0-1048575 pty:master\nunknown /dev/tty 4 1-63 console\n[root@hostname ~]$ cat cascardo/dump\n/dev/tty /dev/tty 5 0 system:/dev/tty\n/dev/console /dev/console 5 1 system:console\n/dev/ptmx /dev/ptmx 5 2 system\n/dev/vc/0 /dev/vc/0 4 0 system:vtmaste[root@hostname ~]$\n\nThis patch drops the driver write queue entirely, using the circular\nbuffer from uart_core only.\n\nSigned-off-by: Thadeu Lima de Souza Cascardo \u003ccascardo@linux.vnet.ibm.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "3e9efdd45f78e0ad859b60906c6556e8efe2579b", "tree": "67a4d184d0e847e4dab1a96342bbdf4f9dc81607", "parents": [ "d5fe5d1648b88aa16b5d97d088d9b743bc9ce0a8" ], "author": { "name": "Ning Jiang", "email": "ning.jiang@marvell.com", "time": "Mon Sep 05 16:28:18 2011 +0800" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Fri Nov 11 09:35:15 2011 -0800" }, "message": "serial-core: power up uart port early before we do set_termios when resuming\n\ncommit 94abc56f4d90f289ea32a0a11d3577fcd8cb28fb upstream.\n\nThe following patch removed uart_change_pm() in uart_resume_port():\n\ncommit 5933a161abcb8d83a2c145177f48027c3c0a8995\nAuthor: Yin Kangkai \u003ckangkai.yin@linux.intel.com\u003e\n serial-core: reset the console speed on resume\n\nIt will break the pxa serial driver when the system resumes from suspend mode\nas it will try to set baud rate divider register in set_termios but with\nclock off.

It means either decrease all refcounts\nif this was a tty reopen or delete the tty if it was newly allocated.\n\nThere was a try to fix this in v3.0-rc2 using tty_release in 0259894c7\n(TTY: fix fail path in tty_open). But instead it introduced a NULL\ndereference. It\u0027s because tty_release dereferences\nfilp-\u003eprivate_data, but that one is set even in our tty_add_file. And\nwhen tty_add_file fails, it\u0027s still NULL/garbage. Hence tty_release\ncannot be called there.\n\nTo circumvent the original leak (and the current NULL deref) we split\ntty_add_file into two functions, making the latter non-failing. In\nthat case we may do the former early in open, where handling failures\nis easy. The latter stays as it is now. So there is no change in\nfunctionality.\n\nThe original bug (leak) was introduced by f573bd176 (tty: Remove\n__GFP_NOFAIL from tty_add_file()). Thanks Dan for reporting this.\n\nLater, we may split tty_release into more functions and call only some\nof them in this fail path instead.

This\nshould immediately fire a THRE interrupt and begin transmitting the\ndata.\nFor buggy UARTs (with UART_BUG_THRE): merely enabling the TX interrupt\nin IER does not necessarily generate a new THRE interrupt.\nTherefore, a background timer periodically checks to see if there is\npending data, and starts transmission if that is the case.\n\nThe bug happens on SMP systems when the system has nothing to transmit,\nthe transmit interrupt is disabled and the following sequence occurs:\n- CPU0: The background timer routine serial8250_backup_timeout()\n starts and saves the state of the interrupt enable register (IER)\n and then disables all interrupts in IER. NOTE: The transmit interrupt\n (TI) bit is saved as disabled.\n- CPU1: The serial core gets data to transmit, grabs the port lock and\n calls serial8250_start_tx() which enables the TI in IER.\n- CPU0: serial8250_backup_timeout() waits for the port lock.\n- CPU1: finishes (with TI enabled) and releases the port lock.\n- CPU0: serial8250_backup_timeout() calls the interrupt routine which\n will transmit the next fifo\u0027s worth of data and then restores the\n IER from the previously saved value (TI disabled).\nAt this point, as long as the serial core has more transmit data\nbuffered, it will not call serial8250_start_tx() again and the\nbackground timer routine will slowly transmit the data.\n\nThe fix is to have serial8250_start_tx() get the port lock before\nit saves the IER state and release it after restoring IER. This will\nprevent serial8250_start_tx() from running in parallel.\n\nSigned-off-by: Al Cooper \u003calcooperx@gmail.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "48fb01de0ab465fab4547cf0160b9185ac6568f0", "tree": "69fb0a7d2a79601479e114c71128407cf5dfab86", "parents": [ "ecc0d72d6d78b59fc324e1283193c6750ef6fd0f" ], "author": { "name": "Eric Smith", "email": "eric@brouhaha.com", "time": "Mon Jul 11 22:53:13 2011 -0600" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Mon Oct 03 11:39:48 2011 -0700" }, "message": "8250_pci: add support for Rosewill RC-305 4x serial port card\n\ncommit 44178176ecc55ad370b837dd2c4b4b8bed1e3823 upstream.\n\nThis patch adds support for the Rosewill RC-305 four-port PCI serial\ncard, and probably any other four-port serial cards based on the\nMoschip MCS9865 chip, assuming that the EEPROM on the card was\nprogrammed in accordance with Table 6 of the MCS9865 EEPROM\nApplication Note version 0.3 dated 16-May-2008, available from the\nMoschip web site (registration required).\n\nThis patch is based on an earlier patch [1] for the SYBA 6x serial\nport card by Ira W.
