However, this is\nreally just a transport to the service processor which implements\nthem either as \"raw\" console (networked consoles, HMC, ...) or as\n\"hvsi\" serial ports.\n\nThe later is a simple packet protocol on top of the raw character\ninterface that is supposed to convey additional \"serial port\" style\nsemantics. In practice however, all it does is provide a way to\nread the CD line and set/clear our DTR line, that\u0027s it.\n\nWe currently implement the \"raw\" protocol as an hvc console backend\n(/dev/hvcN) and the \"hvsi\" protocol using a separate tty driver\n(/dev/hvsi0).\n\nHowever this is quite impractical. The arbitrary difference between\nthe two type of devices has been a major source of user (and distro)\nconfusion. Additionally, there\u0027s an additional mini -hvsi implementation\nin the pseries platform code for our low level debug console and early\nboot kernel messages, which means code duplication, though that low\nlevel variant is impractical as it\u0027s incapable of doing the initial\nprotocol negociation to establish the link to the FSP.\n\nThis essentially replaces the dedicated hvsi driver and the platform\nudbg code completely by extending the existing hvc_vio backend used\nin \"raw\" mode so that:\n\n - It now supports HVSI as well\n - We add support for hvc backend providing tiocm{get,set}\n - It also provides a udbg interface for early debug and boot console\n\nThis is overall less code, though this will only be obvious once we\nremove the old \"hvsi\" driver, which is still available for now. When\nthe old driver is enabled, the new code still kicks in for the low\nlevel udbg console, replacing the old mini implementation in the platform\ncode, it just doesn\u0027t provide the higher level \"hvc\" interface.\n\nIn addition to producing generally simler code, this has several benefits\nover our current situation:\n\n - The user/distro only has to deal with /dev/hvcN for the hypervisor\nconsole, avoiding all sort of confusion that has plagued us in the past\n\n - The tty, kernel and low level debug console all use the same code\nbase which supports the full protocol establishment process, thus the\nconsole is now available much earlier than it used to be with the\nold HVSI driver. The kernel console works much earlier and udbg is\navailable much earlier too. Hackers can enable a hard coded very-early\ndebug console as well that works with HVSI (previously that was only\nsupported for the \"raw\" mode).\n\nI\u0027ve tried to keep the same semantics as hvsi relative to how I react\nto things like CD changes, with some subtle differences though:\n\n - I clear DTR on close if HUPCL is set\n\n - Current hvsi triggers a hangup if it detects a up-\u003edown transition\n on CD (you can still open a console with CD down). My new implementation\n triggers a hangup if the link to the FSP is severed, and severs it upon\n detecting a up-\u003edown transition on CD.\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "048bee7718bb3532aa96d0ce8572cced2ea951e6", "tree": "d29b370d9d467a541b510f60f6316e0f7636bd1a", "parents": [ "725e789f228641fdfafcd65458f0ac78b87acc5a" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Thu Jun 16 15:08:24 2011 +0000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Wed Jun 29 17:48:30 2011 +1000" }, "message": "powerpc/pseries: Factor HVSI header struct in packet definitions\n\nEmbed the struct hvsi_header in the various packet definitions\nrather than open coding it multiple times.

nobody seems to have reported this for any\nreal-life situation yet).\n\nAnd since the workqueue isn\u0027t done from timers and softirq\u0027s any more,\nit\u0027s doubtful whether the CPU useage issue is really relevant any more.\nSo just remove the logic entirely, and see if anybody ever notices.\n\nAlternatively, we might want to re-introduce the \"re-arm the work\" for\njust this case, but then we\u0027d have to re-introduce the delayed work\nmodel or some explicit timer, which really doesn\u0027t seem worth it for\nthis.\n\nReported-and-tested-by: Guillaume Chazarain \u003cguichaz@gmail.com\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nCc: Felipe Balbi \u003cbalbi@ti.com\u003e\nCc: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "e13198894bf6308c097e5678ee315e12b2e1b7a8", "tree": "fcb525252ffd9ac9c44735dc4673a9985a3b9a9d", "parents": [ "514820eb982eb85677ed2ecef9710e90e24fbdab" ], "author": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Wed Jun 08 19:13:06 2011 +0900" }, "committer": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Wed Jun 08 19:13:06 2011 +0900" }, "message": "serial: sh-sci: More unused define purging.\n\nSigned-off-by: Paul Mundt \u003clethal@linux-sh.org\u003e\n" }, { "commit": "514820eb982eb85677ed2ecef9710e90e24fbdab", "tree": "656eb4a0d96ec3e6ac843109cccec862bfcc988e", "parents": [ "debf9507166eede1e676d27d3298cdfb27399cb4" ], "author": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Wed Jun 08 18:51:32 2011 +0900" }, "committer": { "name": "Paul Mundt", "email": "lethal@linux-sh.org", "time": "Wed Jun 08 18:51:32 2011 +0900" }, "message": "serial: sh-sci: Consolidate RXD pin handling.\n\nNon-SCI parts do not have the special port reg necessary for cases where\nthe RX and SCI pins are muxed and need to be manually polled, so these\nlike always fall back on the normal FIFO processing paths.

It is possible to reduce functionality of the\nchips by adding a configuration EEPROM, and the datasheet [1] is\ninconsistent w.r.t subdevices in the 4s+2s1p and 2s1p+4s\nconfigurations. The subdevice-ID 0x3012 should likely read 0x3011 with\na serial port in function 3, which would be consistent with the BAR\nlayouts. For now, the drivers ignore subdevices with ID 0x1000 and no\nclass code.\n\nThe parallel ports are integrated in parport_serial even for purely\nparallel parts to reduce the footprint of the patch.\n\n[1] http://www.moschip.com/data/products/MCS9900/MCS9900_Datasheet.pdf\n\nSigned-off-by: Nicos Gollan \u003cgtdev@spearhead.de\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n" }, { "commit": "cb01ece3ea5dec16ac7bab30069c7736b59f7dea", "tree": "6cc78fe7d08abc855974b2acd91a6fb7a069bee2", "parents": [ "1798ca13bfae8cc7c0ef82c034c3c4951ecaeb88" ], "author": { "name": "leitao@linux.vnet.ibm.com", "email": "leitao@linux.vnet.ibm.com", "time": "Thu May 26 11:18:39 2011 -0300" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Tue Jun 07 09:29:35 2011 -0700" }, "message": "8250: Fix capabilities when changing the port type\n\nWhen changing the port type, the capabilities flags should be changed\nalso, otherwise the capabilities will not correspond to the port type,\nwhich make set_sleep() crash on rmmod.\n\nThis patch just assign the correct capabilites when the port changes.\n\nSigned-off-by: Breno Leitao \u003cleitao@linux.vnet.ibm.com\u003e\nCC: Michael Reed \u003cmreed@linux.vnet.ibm.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n" }, { "commit": "1798ca13bfae8cc7c0ef82c034c3c4951ecaeb88", "tree": "d6ab77bfb20ad5baa2a396fbf49edee8865d471c", "parents": [ "470f22975448a65a1084a6f0721fa5df15323f02" ], "author": { "name": "Alan Cox", "email": "alan@linux.jf.intel.com", "time": "Tue May 24 12:35:48 2011 +0100" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Tue Jun 07 09:25:34 2011 -0700" }, "message": "8250_pci: Fix missing const from merges\n\nSigned-off-by: Alan Cox \u003calan@linux.intel.com\u003e\nSigned-off-by: Antony Pavlov \u003cantony@niisi.msk.ru\u003e\nSigned-off-by: Borislav Petkov \u003cbp@alien8.de\u003e\nSigned-off-by: Vasily Averin \u003cvvs@sw.ru\u003e\nSigned-off-by: Guenter Roeck \u003clinux@roeck-us.net\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n" }, { "commit": "470f22975448a65a1084a6f0721fa5df15323f02", "tree": "91557ad66ac89f6d244150a012eba3c4d7fa09ef", "parents": [ "af99d6f0037d970084b03d9690f50e34d6f70dae" ], "author": { "name": "Boojin Kim", "email": "boojin.kim@samsung.com", "time": "Fri May 27 19:04:03 2011 -0700" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Tue Jun 07 09:25:34 2011 -0700" }, "message": "ARM: SAMSUNG: serial: Fix on handling of one clock source for UART\n\nThis patch fixes the way of comparison for handling of two or more\nclock sources for UART.\n\nFor example, if just only one clock source is defined even though\nthere are two clock sources for UART, the serial driver does not\nset proper clock up.
