This patch adds the product IDs of Huawei's K3765 and K4505 mobile broadband usb modems to option.c. It also adds a quirk to the option probe function so that binding to the device's network interface(class 0xff) is avoided. This is necessary to allow another driver to bind to that, and to ...

Hi, the objection of this patch series is to clean the output device handling up. The end result should be saner code (not setting devices that do not exist) as well as more powerfull control over existing devices and easier addition of new devices.

Things that are still missing and (hopefully) will come in follow up series are device enable/disable ...

Hi, This is V4 of the patches for group_idle and CFQ group charge accounting in terms of IOPS implementation. Since V3 not much has changed. Just more testing and rebase on top of for-2.6.36 branch of block tree. What's the problem ------------------ On high end storage (I got on HP EVA storage array with 12 SATA disks in RAID 5), CFQ's model of dispatching requests from a single queue at a time (sequential readers/write sync writers etc), becomes a bottleneck. Often we don't drive ...

o Implement another CFQ mode where we charge group in terms of number of requests dispatched instead of measuring the time. Measuring in terms of time is not possible when we are driving deeper queue depths and there are requests from multiple cfq queues in the request queue. o This mode currently gets activated if one sets slice_idle=0 and associated disk supports NCQ. Again the idea is that on an NCQ disk with idling disabled most of the queues will dispatch 1 or more requests and ...

The kernel currently provides no functionality to analyze the RSS and swap space usage of each individual sysvipc shared memory segment.

Yes, that's obviously been broken by me, sorry about the trouble. I must have been trying to simplify the error handling by adding a goto at the end of drm_release, which then happened to break the common path. The easiest way to fix this would be to go back to the way drm_release() worked previously and /only/ replace {,un}lock_kernel() with Yes, that sounds good, it's what the code used to do before my broken change. You might also be able to find a way to remove drm_global_lock from ...

It's not. Because when you do autoincrementing write you _can not_ write into param register. You will break the command execution. On the other thought, it may be unnecessary to write unique extra data to every page, so one full register write at the beginning of the command may do. Considering, that legacy memstick is not going to evolve, this may be reasonable assumption. --

It doesn't break dmabounce. What it breaks is the fact that a PCI device which can do 32-bit DMA is connected to a PCI bus which can only access the first 64MB of memory through the host bridge, but the system has more than 64MB available. Allowing a 32-bit DMA mask means that dmabounce can't detect that memory above 64MB needs to be bounced to memory below the 64MB boundary. --

There wasn't a lot of point in optimising it. The current logic, shown in the patch I referenced, is to keep fetching new chunks while the stream position matches the end of the previous chunk we attempted to fetch. To handle multiple outstanding requests, especially if they can be satisfied out-of-order, would have been more complex because the stream position (in the 'really_fetched' variable) wouldn't necessarily match anything interesting. We'd have to keep more state, and the whole ...

My thunderbird with default settings does not replace tabs with spaces. Perhaps the difference between outlook and thunderbird has to do with the method of connecting? On thunderbird you probably use IMAP to get your email from exchange, the IMAP system is horrible on exchange. I suspect it has to do with the implementation of rules regarding spaces.

No, because readers can always share the lock with other readers if there is no writer waiting. If you have one or more readers already holding the lock, with a writer waiting, you have two choices: 1) let the new reader in under the assumption that they'll be quick and won't extend the current "read" usage by much, or 2) block the new reader until after any waiting writers get a chance to get in. The first is called reader priority, The locks are written by glibc and the kernel. I ...

So above we have this loff_t cur_offset = dio->block_in_file << dio->blkbits; loff_t bio_next_offset = dio->logical_offset_in_bio + dio->bio->bi_size; block_in_file is the logical offset of the current page we are working on. logical_offset_in_bio is the logical offset of the first page in the bio, plus bi_size gives us the logical offset that would come next for a contiguous page, so if cur_offset != bio_next_offset then the range in the bio and the ...

"setting the skip flag which would be drained on the next unknown nmi" That's what is wrong, it drops every unknown nmi, no matter when it is detected. In between there could be 1000's of valid other nmis handled. You even could have been returned from nmi mode. But still, the next unknown nmi will be dropped. Your patch could accumulate also the number of unknown nmis to skip, and then, if 'real' unknown nmis happen, all of them will be dropped. -- Advanced Micro Devices, ...

You can trigger unknown NMIs via apic->send_IPI_mask(cpu_mask, NMI_VECTOR). How about the algorithm as follow: int perf_event_nmi_handler() { ... switch (cmd) { case DIE_NMIUNKNOWN: if (per_cpu(perfctr_prev_handled) > 1 && rdtsc() - per_cpu(perfctr_handled_timestamp) < 1000) return NOTIFY_STOP; else return NOTIFY_DONE; } ... handled = x86_pmu.handle_irq(regs); per_cpu(perfctr_prev_handled) = per_cpu(perfctr_handled); per_cpu(perfctr_handled) = handled; if ...

Well as Frederic pointed out the skip variable will never go past one, so That was the intent. Can we guarantee that in the rare cases where the perfctr is generating two nmis, that they will be back-to-back? I think Huang tried to cap my approach even further my creating a time window in which the two nmis had to happen. That gives us the flexibility to handle nmis that are not back to back, but yet deal with the case where two perfctrs fired but we are unsure if it generated a second nmi ...

I guess I am confused. The way I read your patch was that you assumed the next NMI would be the one you skip and if there was another NMI in between the handled one and the one to skip, you would not skip it (nmi count != prev + 1) and it would produce an accidental unknown nmi. I tried to change that with my patch by setting the skip flag which would be drained on the next unknown nmi, independent of where it is in the NMI backlog of NMIs. Did I misread something? Cheers, Don --

I'm following the x86 implementation. I suppose it's done this way since many drivers aren't warning free (as you mention) and turning on -Werror will make it more annoying to find these types of errors. Since there isn't any -Werror=user-copy this approach allows us to find this type of error easily without having to sift through noise. Enabling -Werror in architecture specific code wouldn't help much here though right since this is going to be inlined into drivers and such? -- ...

Do you actually need to disable this if running an older gcc? AFAICT, it should just have no effect at all in that case, so the comment is slightly misleading. Also, why turn this specific warning into an error but not any of the other warnings? Some architectures (alpha, sparc, mips, powerpc, sh) simply turn on -Werror for architecture specific code in general, which seems very useful. We can also make that a config option (probably arch independent) that we turn on for defconfig files that ...

Hmmm... Let's put the two approaches side by side so that we can compare them more easily: Opportunistic Suspend Idle + Timer Jitter Set timer Set timer Suspend OS delays timer Resume OS continues delaying timer Timer fires Timer fires These two cases look quite similar to me.

it has been stated that the android can hit the exact same power state either with sleep or suspend, and that the same clock can wake it up (it appears as a timer expiring for sleep, or an alarm for suspend, but it's the same clock firing the signal) so in at least some cases the hardware supports doing both with equal You are talking about Android as if it was a cell phone only thing, it's not. there are shipping tablets (and I believe netbooks, i.e. laptops) and wakelocks require ...

you specifically stated that suspend would use less power. I am pointing out that ther is info posed in this thread to say that's not always the case. in either case it is possible for the system to wake up again later to let the timer fire and the application save it's work. It's arguably easier in the idle case as it doesn't require application modification for example Idle + Timer Jitter set timer OS sets timer jitter to 1 hour system sleeps for 1 hour with no wakeups timer ...

Yes, the N900 is drastically different, for starters, it has an actual window manager. By multi-tasking I mean me (the user) being able to perform multiple tasks at the same time. For example: writing an email, while browsing the web, while having IM conversations. Obviously not exactly at the same time; start writing an email, go browse for some url, copy, answer a pending IM message, Let's concentrate; Android is the only mobile platform that has expressed interested in suspend ...

Applications need to take smart decisions to save power based on a number of things: is the screen on? is the ear close to the speaker? is there a network available? is it a cellular connection? has the user decided to automatically disconnect from the network after certain time, or at night? etc. I think that, and range timers / ip heartbeat is enough. But that, as you say has been discussed before. Now, only Android has decided to use suspend blockers, that's a *fact*, and I wanted to ...
