This is a common operation in the many select() and poll() variants and needs various, common, sanity checks. poll_select_copy_remaining() is a helper that takes care of copying the remaining time to userspace, as select(), pselect() and ppoll() do.

The core of the patch is replacing the "s64 timeout" with a "struct timespec end_time" in all the plumbing. But most of the diffstat comes from using the just introduced helpers: poll_select_set_timeout poll_select_copy_remaining timespec_add_safe which make manipulating the timespec easier and less error-prone.

This functionality will thus avoid wakeups by running timers before going idle rather than specially waking up for it.

It currently is doing that in userspace which results in: - Huge test scripts that could be a one liner in the kernel - A lot of BIOS bugs are already absorbed by the kernel What do we need such a stupid linuxfirmwarekit for? - Vendors: Can test their BIOSes for Linux compatibility. There will be the time when vendors realize that the test utils on Linux are more strict and using them increases the qualitity and stability of their products. - Vendors: Can easily fix up their BIOSes and be more Linux compatible by: dmesg |grep "Firmware Bug" and send the result to their BIOS developer colleagues who should know what the messages are about and how to fix them, without the need of studying kernel code. - Distributions: can do a first automated HW/BIOS checks. This can then be done without the need of asking kernel developers who need to dig down the code and explain the details. Certification can/will just be rejected until dmesg |grep "Firmware Bug" is empty. - Thus this can be used as an instrument to enforce cleaner BIOS code. Currently every stupid Windows ACPI bug is re-implemented in Linux which is a rather unfortunate situation. We already have the power to avoid this in e.g. memory or cpu hot-plug ACPI implementations, because Linux certification is a must for most vendors in the server area. Working towards being able to do that in the laptop area (vendors are starting to look at Linux here also and will use this tool) is the goal. At least provide them a tool to make it as easy for this guys (e.g. not needing to browse kernel code) as possible. - The ordinary Linux user: can go into the next shop, boots the firmwarekit on his most preferred machines. He chooses one without BIOS bugs. Unsupported HW is ok, he likes to try out latest projects which might support them or likes to dig on it on his own, but he hates to workaround broken BIOSes like hell. I double checked with the firmwarekit. There they have: So the mapping generally is (also depending on how likely the BIOS is to blame, this could sometimes be difficult): FW_INFO = INFO FW_WARN = WARN FW_BUG = FAIL For more info about the linuxfirmwarekit and why this is needed can be found here: http://www.linuxfirmwarekit.org While severity matches with the firmwarekit, it might be tricky to hide messages from the user. E.g. we recently found out that on HP BIOSes negative temperatures are returned, which seem to indicate that the thermal zone is invalid. We can work around that gracefully by ignoring the thermal zone and we do not want to bother the ordinary user with a frightening message: Firmware Bug: thermal management absolutely broken but want to hide it from the user. But in the linuxfirmwarekit this should be shown as a real show stopper (the temperatures could really be wrong, broken thermal management is one of the worst things that can happen and the BIOS guys of the machine must implement this properly).

In the acpi_get_devices the _STA object will be evaluated to check the status of the ACPI device. On some broken BIOS the MYEC object of EC device is initialized as one, which indicates that EC operation region is already accessible before enabling EC device.So on these broken BIOS the EC operation region will be accessed in course of evaluating the _STA object before enabling EC device, which causes that OS will print the following warning messages: >ACPI Error (evregion-0315): No handler for Region [EC__] (ffff88007f8145e8) [EmbeddedControl] [20080609] >ACPI Error (exfldio-0290): Region EmbeddedControl(3) has no handler [20080321] >ACPI Error (psparse-0530): Method parse/execution failed [\_SB_.PCI0.SBRG.

This hurts. We need the rq-locks whenever we change the weight of the per-cpu group sched entities. To allevate this a little, only change the weight when the new weight is at least shares_thresh away from the old value. This avoids the rq-lock for the top level entries, since those will never be re-weighted, and fuzzes the lower level entries a little to gain performance in semi-stable situations.

This patch creates per SPU buffers to hold the data. Data is added to the buffers from in interrupt context. The data is periodically pushed to the kernel buffer via a new Oprofile function oprofile_put_buff(). The oprofile_put_buff() function is called via a work queue enabling the funtion to acquire the mutex lock. The existing user controls for adjusting the per CPU buffer size is used to control the size of the per SPU buffers. Similarly, overflows of the SPU buffers are reported by incrementing the per CPU buffer stats. This eliminates the need to have architecture specific controls for the per SPU buffers which is not acceptable to the OProfile user tool maintainer. The export of the oprofile add_event_entry() is removed as it is no longer needed given this patch. Note, this patch has not addressed the issue of indexing arrays by the spu number. This still needs to be fixed as the spu numbering is not guarenteed to be 0 to max_num_spus-1.

That's this changeset. 2) for each driver convert to new methods. *ALL* drivers are converted in this series. 3) kill the old (renamed) methods.

The current code assumes that all identical prefixes are together in the section: true for normal uses, but not necessarily so if someone overrides MODULE_PARAM_PREFIX. More importantly, it's not true with the new "core_param()" code which uses "kernel" as a prefix. This simplifies the caller for the builtin case, at a slight loss of efficiency (we do the lookup every time to see if the directory exists).

Yet it's ugly to simplify them to module_param(), because by default that inserts a prefix of the module name (usually filename). So, introduce a "core_param". The parameter gets no prefix, but appears in /sys/module/kernel/parameters/ (if non-zero perms arg). I thought about using the name "core", but that's more common than "kernel". And if you create a module called "kernel", you will die a horrible death.

In such case if OS uses the power state returned by the BIOS and checks the device power state very strictly in power transition, the device can't be transited to the correct power state.

The patch implement Function Level Reset(FLR) feature following PCI-e spec. And this is the first step. We would add more generic method, like D0/D3, to allow more devices support this function. The patch contains two functions. pcie_reset_function() is the new driver API, and, contains some action to quiesce a device. The other function is a helper: pcie_execute_reset_function() just executes the reset for a particular device function. Current the usage model is in KVM. Function reset is necessary for assigning device to a guest, or moving it between partitions. For Function Level Reset(FLR), please refer to PCI Express spec chapter 6.6.2.

The names of the detected/claimed slots may be different depending on module load order. For legacy reasons, we need to allow hotplug drivers to override the slot name if a detection driver is loaded first (and they find the same slots). Creating and overriding slot names should be an atomic operation, otherwise you get a locking nightmare as various drivers race to call pci_create_slot(). pci_create_slot() is already serialized by grabbing the pci_bus_sem. We update the API and add a 'hotplug' param, which is: set if the caller is a hotplug driver NULL if the caller is a detection driver pci_create_slot() does not actually use the 'hotplug' parameter in this patch. A later patch will add the logic that uses it.

I'm trying to move the powerpc math-emu code to use the include/math-emu bits. In doing so I've been using TestFloat to see how good or bad we are doing. For the most part the current math-emu code that PPC uses has a number of issues that the code in include/math-emu seems to solve (plus bugs we've had for ever that no one every realized). Anyways, I've come across a case that we are flagging underflow and inexact because we think we have a denormalized result from a double precision divide: 000.FFFFFFFFFFFFF / 3FE.FFFFFFFFFFFFE soft: 001.0000000000000 ..... syst: 001.0000000000000 ...ux What it looks like is the results out of FP_DIV_D are: D: sign: 0 mantissa: 01000000 00000000 exp: -1023 (0) The problem seems like we aren't normalizing the result and bumping the exp. Now that I'm digging into this a bit I'm thinking my issue has to do with the fix DaveM put in place from back in Aug 2007 (commit 405849610fd96b4f34cd1875c4c033228fea6c0f): [MATH-EMU]: Fix underflow exception reporting. 2) we ended up rounding back up to normal (this is the case where we set the exponent to 1 and set the fraction to zero), this should set inexact too ... Another example, "0x0.0000000000001p-1022 / 16.0", should signal both inexact and underflow. The cpu implementations and ieee1754 literature is very clear about this. This is case #2 above. Here is the distilled glibc test case from Jakub Jelinek which prompted that commit: -------------------- #include #include #include volatile double d = DBL_MIN; volatile double e = 0x0.0000000000001p-1022; volatile double f = 16.0; int main (void) { printf ("%x\n", fetestexcept (FE_UNDERFLOW)); d /= f; printf ("%x\n", fetestexcept (FE_UNDERFLOW)); e /= f; printf ("%x\n", fetestexcept (FE_UNDERFLOW)); return 0; } -------------------- It looks like the case I have we are exact before rounding, but think it looks like the rounding case since it appears as if "overflow is set". 000.FFFFFFFFFFFFF / 3FE.FFFFFFFFFFFFE = 001.0000000000000 I think the following adds the check for my case and still works for the issue your commit was trying to resolve.
