      "message": "[PATCH] TTY layer buffering revamp\n\nThe API and code have been through various bits of initial review by\nserial driver people but they definitely need to live somewhere for a\nwhile so the unconverted drivers can get knocked into shape, existing\ndrivers that have been updated can be better tuned and bugs whacked out.\n\nThis replaces the tty flip buffers with kmalloc objects in rings. In the\nnormal situation for an IRQ driven serial port at typical speeds the\nbehaviour is pretty much the same, two buffers end up allocated and the\nkernel cycles between them as before.\n\nWhen there are delays or at high speed we now behave far better as the\nbuffer pool can grow a bit rather than lose characters. This also means\nthat we can operate at higher speeds reliably.\n\nFor drivers that receive characters in blocks (DMA based, USB and\nespecially virtualisation) the layer allows a lot of driver specific\ncode that works around the tty layer with private secondary queues to be\nremoved. The IBM folks need this sort of layer, the smart serial port\npeople do, the virtualisers do (because a virtualised tty typically\noperates at infinite speed rather than emulating 9600 baud).\n\nFinally many drivers had invalid and unsafe attempts to avoid buffer\noverflows by directly invoking tty methods extracted out of the innards\nof work queue structs. These are no longer needed and all go away. That\nfixes various random hangs with serial ports on overflow.\n\nThe other change in here is to optimise the receive_room path that is\nused by some callers. It turns out that only one ldisc uses receive room\nexcept asa constant and it updates it far far less than the value is\nread. We thus make it a variable not a function call.\n\nI expect the code to contain bugs due to the size alone but I\u0027ll be\nwatching and squashing them and feeding out new patches as it goes.\n\nBecause the buffers now dynamically expand you should only run out of\nbuffering when the kernel runs out of memory for real.  That means a lot of\nthe horrible hacks high performance drivers used to do just aren\u0027t needed any\nmore.\n\nDescription:\n\ntty_insert_flip_char is an old API and continues to work as before, as does\ntty_flip_buffer_push() [this is why many drivers dont need modification].  It\ndoes now also return the number of chars inserted\n\nThere are also\n\ntty_buffer_request_room(tty, len)\n\nwhich asks for a buffer block of the length requested and returns the space\nfound.  This improves efficiency with hardware that knows how much to\ntransfer.\n\nand tty_insert_flip_string_flags(tty, str, flags, len)\n\nto insert a string of characters and flags\n\nFor a smart interface the usual code is\n\n    len \u003d tty_request_buffer_room(tty, amount_hardware_says);\n    tty_insert_flip_string(tty, buffer_from_card, len);\n\nMore description!\n\nAt the moment tty buffers are attached directly to the tty.  This is causing a\nlot of the problems related to tty layer locking, also problems at high speed\nand also with bursty data (such as occurs in virtualised environments)\n\nI\u0027m working on ripping out the flip buffers and replacing them with a pool of\ndynamically allocated buffers.  This allows both for old style \"byte I/O\"\ndevices and also helps virtualisation and smart devices where large blocks of\ndata suddenely materialise and need storing.\n\nSo far so good.  Lots of drivers reference tty-\u003eflip.*.  Several of them also\ncall directly and unsafely into function pointers it provides.  This will all\nbreak.  Most drivers can use tty_insert_flip_char which can be kept as an API\nbut others need more.\n\nAt the moment I\u0027ve added the following interfaces, if people think more will\nbe needed now is a good time to say\n\n int tty_buffer_request_room(tty, size)\n\nTry and ensure at least size bytes are available, returns actual room (may be\nzero).  At the moment it just uses the flipbuf space but that will change.\nRepeated calls without characters being added are not cumulative.  (ie if you\ncall it with 1, 1, 1, and then 4 you\u0027ll have four characters of space.  The\nother functions will also try and grow buffers in future but this will be a\nmore efficient way when you know block sizes.\n\n int tty_insert_flip_char(tty, ch, flag)\n\nAs before insert a character if there is room.  Now returns 1 for success, 0\nfor failure.\n\n int tty_insert_flip_string(tty, str, len)\n\nInsert a block of non error characters.  Returns the number inserted.\n\n int tty_prepare_flip_string(tty, strptr, len)\n\nAdjust the buffer to allow len characters to be added.  Returns a buffer\npointer in strptr and the length available.  This allows for hardware that\nneeds to use functions like insl or mencpy_fromio.\n\nSigned-off-by: Alan Cox \u003calan@redhat.com\u003e\nCc: Paul Fulghum \u003cpaulkf@microgate.com\u003e\nSigned-off-by: Hirokazu Takata \u003ctakata@linux-m32r.org\u003e\nSigned-off-by: Serge Hallyn \u003cserue@us.ibm.com\u003e\nSigned-off-by: Jeff Dike \u003cjdike@addtoit.com\u003e\nSigned-off-by: John Hawkes \u003chawkes@sgi.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
