0020d3e Hans Verkuil 30 March 2006, 22:50:34 UTC V4L/DVB (3693): Fix msp3400c and bttv stereo/mono/bilingual detection/handling - msp3400c did not detect the second carrier, thus being always mono. - properly mute the msp3400c while detecting the carrier. - fix checks on the presence of scart2/3 inputs and scart 2 output. - implement proper audio mode fallbacks for msp3400c/d, identical to the way msp3400g works. - MODE_STEREO no longer produces dual languages when set for a bilingual transmission, instead it falls back to LANG1. Use LANG1_LANG2 to hear both languages of a bilingual transmission. This is much more intuitive for the user and is in accordance with the preferred usage in the v4l2 specification. - bttv tried to implement v4l2 calls with v4l1 calls to the i2c devices, completely mangling the audmode/rxsubchans handling. v4l2 calls now do v4l2 calls to the i2c devices. - fixed broken i2c_vidiocschan in bttv. - add start/end lines to LOG_STATUS.

86f40cc Andrew de Quincey 30 March 2006, 18:53:35 UTC V4L/DVB (3673): Fix budget-av CAM reset Unfortunately on the budget-av board, the CAM reset line is tied to the frontend reset line, so resetting the CAM also zaps the frontend. This breaks the tda1004x at least, and causes it to fail to tune until the budget-av module is reloaded. This patch adds an exported function to dvb_frontend that allows a card to forcibly reinitialise a frontend. The budget-av now does this on CAM reset, which corrects this problem. since they do not tie the CAM reset line to the frontend reset line.

5e85bd0 Trent Piepho 30 March 2006, 18:53:32 UTC V4L/DVB (3672): Fix memory leak in dvr open The dvr device could be opened multiple times simultaneously in O_RDONLY mode. Each open after the first would allocate a new dvr buffer (1880 KB) and leak the old buffer. The first close would de-allocate the dvr buffer and cause all other open dvrs to stop working. This patch allows only a single O_RDONLY open of the drv device, as per the API specification. Multiple O_WRONLY opens are still allowed and don't appear to cause any problems.

2f03ee8 C.Y.M 30 March 2006, 07:31:48 UTC V4L/DVB (3671): New module parameter 'tv_standard' (dvb-ttpci driver) This attached patch was originally proposed by Anssi Hannula to the dvb-kernel user to choose the default broadcast mode when using the ttpci driver. NTSC users need to only add the following line to modprobe.d: options dvb-ttpci tv_standard=1 PAL users will not need to change anything, for this will be the default.

cc33668 Mauro Carvalho Chehab 29 March 2006, 19:29:00 UTC V4L/DVB (3667a): Fix SAP + stereo mode at msp3400 It should be V4L2_TUNER_MODE_LANG1_LANG2. What the code does is check if we are NTSC and a SAP channel is available. If so, then the msp3400 should switch to standard 0x21 if the user wants to hear the SAP channel, which is for audio modes LANG2 (aka SAP) and LANG1_LANG2 (bilingual). In the msp3400 driver STEREO is abused for bilingual in PAL. Bilingual never worked with NTSC in the past and I decided that I'd better not use the bad PAL example.

Previously this had been set to 1024 but unfortunately some I2C implementations can't transfer data in such big gulps. Specifically, the pvrusb2 driver has a hard limit of around 60 bytes, due to the encapsulation there of I2C traffic into USB messages. So we have to significantly reduce this parameter.

e9917a0 Steve French 31 March 2006, 21:22:00 UTC [CIFS] Incorrect signature sent on SMB Read Fixes Samba bug 3621 and kernel.org bug 6147 For servers which require SMB/CIFS packet signing, we were sending the wrong signature (all zeros) on SMB Read request. The new cifs routine to do signatures across an iovec was not complete - and SMB Read, unlike the new SMBWrite2, did not fall back to the older routine (ie use SendReceive vs. the more efficient SendReceive2 ie used the older cifs_sign_smb vs. the disabled cifs_sign_smb2) for calculating signatures. This finishes up cifs_sign_smb2/cifs_calc_signature2 so that the callers of SendReceive2 can get SMB/CIFS packet signatures. Now that cifs_sign_smb2 is supported, we could start using it in the write path but this smaller fix does not include the change to use SMBWrite2 when signatures are required (which when enabled will make more Writes more efficient and alloc less memory). Currently Write2 is only used when signatures are not required at the moment but after more testing we will enable that as well). Thanks to James Slepicka and Sam Flory for initial investigation.

108b42b David Howells 31 March 2006, 15:00:29 UTC [PATCH] Document Linux's memory barriers [try #7] The attached patch documents the Linux kernel's memory barriers. I've updated it from the comments I've been given. The per-arch notes sections are gone because it's clear that there are so many exceptions, that it's not worth having them. I've added a list of references to other documents. I've tried to get rid of the concept of memory accesses appearing on the bus; what matters is apparent behaviour with respect to other observers in the system. Interrupts barrier effects are now considered to be non-existent. They may be there, but you may not rely on them. I've added a couple of definition sections at the top of the document: one to specify the minimum execution model that may be assumed, the other to specify what this document refers to by the term "memory". I've made greater mention of the use of mmiowb(). I've adjusted the way in which caches are described, and described the fun that can be had with cache coherence maintenance being unordered and data dependency not being necessarily implicit. I've described (smp_)read_barrier_depends(). I've rearranged the order of the sections, so that memory barriers are discussed in abstract first, and then described the memory barrier facilities available on Linux, before going on to more real-world discussions and examples. I've added information about the lack of memory barriering effects with atomic ops and bitops. I've added information about control dependencies. I've added more diagrams to illustrate caching interactions between CPUs.

6ca0176 Richard Purdie 31 March 2006, 10:31:49 UTC [PATCH] backlight: Backlight Class Improvements Backlight class attributes are currently easy to implement incorrectly. Moving certain handling into the backlight core prevents this whilst at the same time makes the drivers simpler and consistent. The following changes are included: The brightness attribute only sets and reads the brightness variable in the backlight_properties structure. The power attribute only sets and reads the power variable in the backlight_properties structure. Any framebuffer blanking events change a variable fb_blank in the backlight_properties structure. The backlight driver has only two functions to implement. One function is called when any of the above properties change (to update the backlight brightness), the second is called to return the current backlight brightness value. A new attribute "actual_brightness" is added to return this brightness as determined by the driver having combined all the above factors (and any driver/device specific factors). Additionally, the backlight core takes care of checking the maximum brightness is not exceeded and of turning off the backlight before device removal. The corgi backlight driver is updated to reflect these changes.

92476d7 Eric W. Biederman 31 March 2006, 10:31:42 UTC [PATCH] pidhash: Refactor the pid hash table Simplifies the code, reduces the need for 4 pid hash tables, and makes the code more capable. In the discussions I had with Oleg it was felt that to a large extent the cleanup itself justified the work. With struct pid being dynamically allocated meant we could create the hash table entry when the pid was allocated and free the hash table entry when the pid was freed. Instead of playing with the hash lists when ever a process would attach or detach to a process. For myself the fact that it gave what my previous task_ref patch gave for free with simpler code was a big win. The problem is that if you hold a reference to struct task_struct you lock in 10K of low memory. If you do that in a user controllable way like /proc does, with an unprivileged but hostile user space application with typical resource limits of 1000 fds and 100 processes I can trigger the OOM killer by consuming all of low memory with task structs, on a machine wight 1GB of low memory. If I instead hold a reference to struct pid which holds a pointer to my task_struct, I don't suffer from that problem because struct pid is 2 orders of magnitude smaller. In fact struct pid is small enough that most other kernel data structures dwarf it, so simply limiting the number of referring data structures is enough to prevent exhaustion of low memory. This splits the current struct pid into two structures, struct pid and struct pid_link, and reduces our number of hash tables from PIDTYPE_MAX to just one. struct pid_link is the per process linkage into the hash tables and lives in struct task_struct. struct pid is given an indepedent lifetime, and holds pointers to each of the pid types. The independent life of struct pid simplifies attach_pid, and detach_pid, because we are always manipulating the list of pids and not the hash table. In addition in giving struct pid an indpendent life it makes the concept much more powerful. Kernel data structures can now embed a struct pid * instead of a pid_t and not suffer from pid wrap around problems or from keeping unnecessarily large amounts of memory allocated.

8c7904a Eric W. Biederman 31 March 2006, 10:31:37 UTC [PATCH] task: RCU protect task->usage A big problem with rcu protected data structures that are also reference counted is that you must jump through several hoops to increase the reference count. I think someone finally implemented atomic_inc_not_zero(&count) to automate the common case. Unfortunately this means you must special case the rcu access case. When data structures are only visible via rcu in a manner that is not determined by the reference count on the object (i.e. tasks are visible until their zombies are reaped) there is a much simpler technique we can employ. Simply delaying the decrement of the reference count until the rcu interval is over. What that means is that the proc code that looks up a task and later wants to sleep can now do: rcu_read_lock(); task = find_task_by_pid(some_pid); if (task) { get_task_struct(task); } rcu_read_unlock(); The effect on the rest of the kernel is that put_task_struct becomes cheaper and immediate, and in the case where the task has been reaped it frees the task immediate instead of unnecessarily waiting an until the rcu interval is over. Cleanup of task_struct does not happen when its reference count drops to zero, instead cleanup happens when release_task is called. Tasks can only be looked up via rcu before release_task is called. All rcu protected members of task_struct are freed by release_task. Therefore we can move call_rcu from put_task_struct into release_task. And we can modify release_task to not immediately release the reference count but instead have it call put_task_struct from the function it gives to call_rcu. The end result: - get_task_struct is safe in an rcu context where we have just looked up the task. - put_task_struct() simplifies into its old pre rcu self. This reorganization also makes put_task_struct uncallable from modules as it is not exported but it does not appear to be called from any modules so this should not be an issue, and is trivially fixed.

390e2ff Eric W. Biederman 31 March 2006, 10:31:33 UTC [PATCH] Make setsid() more robust The core problem: setsid fails if it is called by init. The effect in 2.6.16 and the earlier kernels that have this problem is that if you do a "ps -j 1 or ps -ej 1" you will see that init and several of it's children have process group and session == 0. Instead of process group == session == 1. Despite init calling setsid. The reason it fails is that daemonize calls set_special_pids(1,1) on kernel threads that are launched before /sbin/init is called. The only remaining effect in that current->signal->leader == 0 for init instead of 1. And the setsid call fails. No one has noticed because /sbin/init does not check the return value of setsid. In 2.4 where we don't have the pidhash table, and daemonize doesn't exist setsid actually works for init. I care a lot about pid == 1 not being a special case that we leave broken, because of the container/jail work that I am doing. - Carefully allow init (pid == 1) to call setsid despite the kernel using its session. - Use find_task_by_pid instead of find_pid because find_pid taking a pidtype is going away.

7c4bb1f Con Kolivas 31 March 2006, 10:31:29 UTC [PATCH] sched: remove on runqueue requeueing On runqueue time is used to elevate priority in schedule(). In the code it currently requeues tasks even if their priority is not elevated, which would end up placing them at the end of their runqueue array effectively delaying them instead of improving their priority. Bug spotted by Mike Galbraith <efault@gmx.de> This patch removes this requeueing.

There is a bug in the current code that also penalises tasks that already have high priority. Correct that bug.

e7c38cb Con Kolivas 31 March 2006, 10:31:25 UTC [PATCH] sched: make task_noninteractive use sleep_type Alterations to the pipe code in the kernel made it possible for relative starvation to occur with tasks that slept waiting on a pipe getting unfair priority bonuses even if they were otherwise fully cpu bound so the TASK_NONINTERACTIVE flag was introduced which prevented any change to sleep_avg while sleeping waiting on a pipe. This change also leads to the converse though, preventing any priority boost from occurring in truly interactive tasks that wait on pipes. Convert the TASK_NONINTERACTIVE flag to set sleep_type to SLEEP_NONINTERACTIVE which will allow a linear bonus to priority based on sleep time thus allowing interactive tasks to get high priority if they sleep enough.

db1b1fe Jack Steiner 31 March 2006, 10:31:21 UTC [PATCH] sched: reduce overhead of calc_load Currently, count_active_tasks() calls both nr_running() & nr_interruptible(). Each of these functions does a "for_each_cpu" & reads values from the runqueue of each cpu. Although this is not a lot of instructions, each runqueue may be located on different node. Depending on the architecture, a unique TLB entry may be required to access each runqueue. Since there may be more runqueues than cpu TLB entries, a scan of all runqueues can trash the TLB. Each memory reference incurs a TLB miss & refill. In addition, the runqueue cacheline that contains nr_running & nr_uninterruptible may be evicted from the cache between the two passes. This causes unnecessary cache misses. Combining nr_running() & nr_interruptible() into a single function substantially reduces the TLB & cache misses on large systems. This should have no measureable effect on smaller systems. On a 128p IA64 system running a memory stress workload, the new function reduced the overhead of calc_load() from 605 usec/call to 324 usec/call.
