| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit df16c33a4028159d1ba8a7061c9fa950b58d1a61 ] IIO_CONCENTRATION together with INFO_RAW specifier is used for reporting raw concentrations of pollutants. Raw value should be meaningless before being properly scaled. Because of that description shouldn't mention raw value unit whatsoever. Fix this by rephrasing existing description so it follows conventions used throughout IIO ABI docs.

New microcode serializes the processor access during the execution of RDRAND and RDSEED. This ensures that the shared buffer is overwritten before it is released for reuse. While it is present on all affected CPU models, the microcode mitigation is not needed on models that enumerate ARCH_CAPABILITIES[MDS_NO] in the cases where TSX is not supported or has been disabled with TSX_CTRL. The mitigation is activated by default on affected processors and it increases latency for RDRAND and RDSEED instructions. Among other effects this will reduce throughput from /dev/urandom. * Enable administrator to configure the mitigation off when desired using either mitigations=off or srbds=off. * Export vulnerability status via sysfs * Rename file-scoped macros to apply for non-whitelist table initializations.

Some processors may incur a machine check error possibly resulting in an unrecoverable CPU lockup when an instruction fetch encounters a TLB multi-hit in the instruction TLB. This can occur when the page size is changed along with either the physical address or cache type. The relevant erratum can be found here: https://bugzilla.kernel.org/show_bug.cgi?id=205195 There are other processors affected for which the erratum does not fully disclose the impact. This issue affects both bare-metal x86 page tables and EPT. It can be mitigated by either eliminating the use of large pages or by using careful TLB invalidations when changing the page size in the page tables. Just like Spectre, Meltdown, L1TF and MDS, a new bit has been allocated in MSR_IA32_ARCH_CAPABILITIES (PSCHANGE_MC_NO) and will be set on CPUs which are mitigated against this issue.

| * | ANDROID: cpufreq: times: add /proc/uid_concurrent_{active,policy}_timeConnor O'Brien2019-11-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to model the energy used by the cpu, we need to expose cpu time information to userspace. We can use this information to blame uids for the energy they are using. This patch adds 2 files: /proc/uid_concurrent_active_time outputs the time each uid spent running with 1 to num_possible_cpus online and not idle. For instance, if 4 cores are online and active for 50ms and the uid is running on one of the cores, the uid should be blamed for 1/4 of the base energy used by the cpu when 1 or more cores is active. /proc/uid_concurrent_policy_time outputs the time each uid spent running on group of cpu's with the same policy with 1 to num_related_cpus online and not idle. For instance, if 2 cores that are a part of the same policy are online and active for 50ms and the uid is running on one of the cores, the uid should be blamed for 1/2 of the energy that is used everytime one or more cpus in the same policy is active. This patch is based on commit c89e69136fec ("ANDROID: cpufreq: uid_concurrent_active_time") and commit 989212536842 ("ANDROID: cpufreq: uid_concurrent_policy_time") in the android-msm-wahoo-4.4 kernel by Marissa Wall.

We can use this information to blame uids for the energy they are using. This patch adds 2 files: /proc/uid_concurrent_active_time outputs the time each uid spent running with 1 to num_possible_cpus online and not idle. For instance, if 4 cores are online and active for 50ms and the uid is running on one of the cores, the uid should be blamed for 1/4 of the base energy used by the cpu when 1 or more cores is active. /proc/uid_concurrent_policy_time outputs the time each uid spent running on group of cpu's with the same policy with 1 to num_related_cpus online and not idle. For instance, if 2 cores that are a part of the same policy are online and active for 50ms and the uid is running on one of the cores, the uid should be blamed for 1/2 of the energy that is used everytime one or more cpus in the same policy is active. This patch is based on commit c89e69136fec ("ANDROID: cpufreq: uid_concurrent_active_time") and commit 989212536842 ("ANDROID: cpufreq: uid_concurrent_policy_time") in the android-msm-wahoo-4.4 kernel by Marissa Wall.

| | * | | | f2fs: Add option to limit required GC for checkpoint=disableDaniel Rosenberg2019-06-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This extends the checkpoint option to allow checkpoint=disable:%u[%] This allows you to specify what how much of the disk you are willing to lose access to while mounting with checkpoint=disable. If the amount lost would be higher, the mount will return -EAGAIN. This can be given as a percent of total space, or in blocks. Currently, we need to run garbage collection until the amount of holes is smaller than the OVP space. With the new option, f2fs can mark space as unusable up front instead of requiring garbage collection until the number of holes is small enough.

Android regularly "samples" the memory usage of various processes in order to balance its memory pool sizes. This sampling process involves opening /proc/pid/smaps and summing certain fields. For very large processes, sampling memory use this way can take several hundred milliseconds, due mostly to the overhead of the seq_printf calls in task_mmu.c. smaps_rollup improves the situation. It contains most of the fields of /proc/pid/smaps, but instead of a set of fields for each VMA, smaps_rollup instead contains one synthetic smaps-format entry representing the whole process. In the single smaps_rollup synthetic entry, each field is the summation of the corresponding field in all of the real-smaps VMAs. Using a common format for smaps_rollup and smaps allows userspace parsers to repurpose parsers meant for use with non-rollup smaps for smaps_rollup, and it allows userspace to switch between smaps_rollup and smaps at runtime (say, based on the availability of smaps_rollup in a given kernel) with minimal fuss. By using smaps_rollup instead of smaps, a caller can avoid the significant overhead of formatting, reading, and parsing each of a large process's potentially very numerous memory mappings. For sampling system_server's PSS in Android, we measured a 12x speedup, representing a savings of several hundred milliseconds. One alternative to a new per-process proc file would have been including PSS information in /proc/pid/status. We considered this option but thought that PSS would be too expensive (by a few orders of magnitude) to collect relative to what's already emitted as part of /proc/pid/status, and slowing every user of /proc/pid/status for the sake of readers that happen to want PSS feels wrong. The code itself works by reusing the existing VMA-walking framework we use for regular smaps generation and keeping the mem_size_stats structure around between VMA walks instead of using a fresh one for each VMA. In this way, summation happens automatically. We let seq_file walk over the VMAs just as it does for regular smaps and just emit nothing to the seq_file until we hit the last VMA. Benchmarks: using smaps: iterations:1000 pid:1163 pss:220023808 0m29.46s real 0m08.28s user 0m20.98s system using smaps_rollup: iterations:1000 pid:1163 pss:220702720 0m04.39s real 0m00.03s user 0m04.31s system We're using the PSS samples we collect asynchronously for system-management tasks like fine-tuning oom_adj_score, memory use tracking for debugging, application-level memory-use attribution, and deciding whether we want to kill large processes during system idle maintenance windows. Android has been using PSS for these purposes for a long time; as the average process VMA count has increased and and devices become more efficiency-conscious, PSS-collection inefficiency has started to matter more. IMHO, it'd be a lot safer to optimize the existing PSS-collection model, which has been fine-tuned over the years, instead of changing the memory tracking approach entirely to work around smaps-generation inefficiency. Tim said: : There are two main reasons why Android gathers PSS information: : : 1. Android devices can show the user the amount of memory used per : application via the settings app. This is a less important use case. : : 2. We log PSS to help identify leaks in applications. We have found : an enormous number of bugs (in the Android platform, in Google's own : apps, and in third-party applications) using this data. : : To do this, system_server (the main process in Android userspace) will : sample the PSS of a process three seconds after it changes state (for : example, app is launched and becomes the foreground application) and about : every ten minutes after that. The net result is that PSS collection is : regularly running on at least one process in the system (usually a few : times a minute while the screen is on, less when screen is off due to : suspend). PSS of a process is an incredibly useful stat to track, and we : aren't going to get rid of it. We've looked at some very hacky approaches : using RSS ("take the RSS of the target process, subtract the RSS of the : zygote process that is the parent of all Android apps") to reduce the : accounting time, but it regularly overestimated the memory used by 20+ : percent. Accordingly, I don't think that there's a good alternative to : using PSS. : : We started looking into PSS collection performance after we noticed random : frequency spikes while a phone's screen was off; occasionally, one of the : CPU clusters would ramp to a high frequency because there was 200-300ms of : constant CPU work from a single thread in the main Android userspace : process. The work causing the spike (which is reasonable governor : behavior given the amount of CPU time needed) was always PSS collection. : As a result, Android is burning more power than we should be on PSS : collection. : : The other issue (and why I'm less sure about improving smaps as a : long-term solution) is that the number of VMAs per process has increased : significantly from release to release. After trying to figure out why we : were seeing these 200-300ms PSS collection times on Android O but had not : noticed it in previous versions, we found that the number of VMAs in the : main system process increased by 50% from Android N to Android O (from : ~1800 to ~2700) and varying increases in every userspace process. Android : M to N also had an increase in the number of VMAs, although not as much. : I'm not sure why this is increasing so much over time, but thinking about : ASLR and ways to make ASLR better, I expect that this will continue to : increase going forward. I would not be surprised if we hit 5000 VMAs on : the main Android process (system_server) by 2020. : : If we assume that the number of VMAs is going to increase over time, then : doing anything we can do to reduce the overhead of each VMA during PSS : collection seems like the right way to go, and that means outputting an : aggregate statistic (to avoid whatever overhead there is per line in : writing smaps and in reading each line from userspace).

Historically according to the (now deprecated) USB 3.0 specification a SuperSpeed host downstream port would automatically transition to Compliance mode from the Polling state if LFPS polling times out. However the language in USB 3.1 as well as xHCI 1.1 states it may be required to explicitly enable this transition. For such hosts this is done by sending a SET_FEATURE(PORT_LINK_STATE) with the state set to Compliance to the root hub port. Similar to the other supported commands, to do this via sysfs: echo > /sys/bus/usb/devices/2-0\:1.0/enable_compliance According to xHCI 1.1 section 4.19.1.2.4.1, this enables the transition to compliance mode upon LFPS timeout. Note that this can only be issued when the port is in disconnected state. And in order to disable this behavior on subsequent transitions, a warm reset should be issued. So add another entry to do that: echo > /sys/bus/usb/devices/2-0\:1.0/warm_reset In general these attributes can also be useful for other USB SuperSpeed compliance tests such as electrical and eye diagram testing which require CPn patterns to be transmitted.

* | | | | usb: gadget: add f_uac1 variant based on a new u_audio apiAjay Agarwal2018-12-20

Comparing to legacy f_uac1 function implementation it doesn't require any real Audio codec to be present on the device. In f_uac1 audio streams are simply sinked to and sourced from a virtual ALSA sound card created using u_audio API. Legacy f_uac1 approach is to write audio samples directly to existing ALSA sound card f_uac1 approach is more generic/flexible one - create an ALSA sound card that represents USB Audio function and allows to be used by userspace application that may choose to do whatever it wants with the data received from the USB Host and choose to provide whatever it wants as audio data to the USB Host. f_uac1 also has capture support (gadget->host) thanks to easy implementation via u_audio. By default, capture interface has 48000kHz/2ch configuration, same as playback channel has. f_uac1 descriptors naming convention uses f_uac2 driver naming convention that makes it more common and meaningful. Comparing to f_uac1_legacy, the f_uac1 doesn't have volume/mute functionality. This is because the f_uac1 volume/mute feature unit was dummy implementation since that driver creation (2009) and never had any real volume control or mute functionality, so there is no any difference here. Since f_uac1 functionality, exposed interface to userspace (virtual ALSA card), input parameters are so different comparing to f_uac1_legacy, that there is no any reason to keep them in the same file/module, and separate function was created.

However, issuing smaller discard may cost more lifetime but releasing less free space in flash device. Since f2fs has ability of separating hot/cold data and garbage collection, we can expect that small-sized invalid region would expand soon with OPU, deletion or garbage collection on valid datas, so it's better to delay or skip issuing smaller size discards, it could help to reduce overmuch consumption of IO bandwidth and lifetime of flash storage. This patch makes f2fs selectng 64K size as its default minimal granularity, and issue discard with the size which is not smaller than minimal granularity. Also it exposes discard granularity as sysfs entry for configuration in different scenario. Jaegeuk Kim: We must issue all the accumulated discard commands when fstrim is called. So, I've added pend_list_tag[] to indicate whether we should issue the commands or not. If tag sets P_ACTIVE or P_TRIM, we have to issue them. P_TRIM is set once at a time, given fstrim trigger. In addition, issue_discard_thread is calling too much due to the number of discard commands remaining in the pending list. I added a timer to control it likewise gc_thread.
