RE: clarification on tap_timeout function

by P T, Sarath

Hi Team, Can anyone help me on this ? Hope you will do the needful as soon as possible. Regards Sarath P T From: P T, Sarath Sent: 14 March 2022 13:19 To: 'linux-kselftest-mirror(a)lists.linaro.org' <linux-kselftest-mirror(a)lists.linaro.org> Subject: clarification on tap_timeout function Hi Team, I need a clarification the function "tap_timeout" which is being used in the runner.sh , the one will give the result format in the TAP 13 protocol. Below I am giving the function. tap_timeout() { # Make sure tests will time out if utility is available. if [ -x /usr/bin/timeout ] ; then /usr/bin/timeout --foreground "$kselftest_timeout" "$1" else "$1" fi } Need a clarification why we are using the function "tap_timout" and why the "kselftest_timeout" variable declared as 45 seconds by default. It will be very helpful if you are clarifying these things for me. Regards Sarath PT

[PATCH] Fix kernel build with LLVM=1

by Grigory Vasilyev

The wrong logic is using 1 as a suffix instead of -1. So the build script tries to find clang1 file instead of clang.

[PATCH 1/2] [RFC] rtc: expose direct access to hardware alarm time in debugfs

by Mateusz Jończyk

Before Linux 5.17, there was a problem with the CMOS RTC driver: cmos_read_alarm() and cmos_set_alarm() did not check for the UIP (Update in progress) bit, which could have caused it to sometimes fail silently and read bogus values or do not set the alarm correctly. Luckily, this issue was masked by cmos_read_time() invocations in core RTC code - see https://marc.info/?l=linux-rtc&m=164858416511425&w=4 To avoid such a problem in the future in some other driver, I wrote a test unit that reads the alarm time many times in a row. As the alarm time is usually read once and cached by the RTC core, this requires a way for userspace to trigger direct alarm time read from hardware. I think that debugfs is the natural choice for this. So, introduce /sys/kernel/debug/rtc/rtcX/wakealarm_raw. This interface as implemented here does not seem to be that useful to userspace, so there is little risk that it will become kernel ABI. Is this approach correct and worth it? TODO: - should I add a new Kconfig option (like CONFIG_RTC_INTF_DEBUGFS), or just use CONFIG_DEBUG_FS here? I wouldn't like to create unnecessary config options in the kernel.

It does not make sense to me because, as proven with my test, the two threads end up sharing the same stack memory. Reinette

あいさつ。

by Mrs Isabella Sayouba

あいさつ。涙を流しながらこのメールを書いています。私の目には大きな悲しみがあります。私の名前はイザベラ・サヨウバさんです。チュニジア出身で、ブルキナファソの病院から連絡を取ります。私はあなたに心を開いて感動したので、あなたに話す以外に選択肢はありません。私は、2011年に亡くなる前にブルキナファソのチュニジア大使と9年間働いていたSayouba Brown氏と結婚しました。子供なしで11年間結婚した。彼はたった5日間続いた短い病気の後で死にました。彼の死後、私は再婚しないことに決めました。亡くなった夫が生きていたとき、彼は総額850万ドルを預けました。（800万5000ドル）西アフリカのブルキナファソの首都ワガドゥグーの銀行で。現在、このお金はまだ銀行にあります。彼はこのお金をブルキナファソの鉱業からの金の輸出に利用できるようにしました。最近、私の医者は私が癌と脳卒中の問題のために7ヶ月間は続かないだろうと私に言いました。私を最も悩ませているのは脳卒中の病気です。私の状態を知ったので、私はこのお金をあなたに渡して、恵まれない人々の世話をすることにしました。あなたはこのお金を私がここで指示する方法で利用するでしょう。私はあなたにあなたの個人的な使用のために総お金の30パーセントを取って欲しいです。お金の70％は私の名前で孤児院を建て、通りの貧しい人々を助けるために使うでしょう。私は孤児として育ちましたが、神の家を維持するためだけに、家族には誰もいません。この病気が私をとても苦しめたので、神が私の罪を赦し、楽園で私の魂を受け入れるようにこれをしているのです。返信を受け取り次第、ブルキナファソの銀行の連絡先をお知らせします。また、銀行の現在の受取人であることを証明する権限書を発行するよう銀行長に指示します。私がここで述べたようにあなたがそれに応じて行動することを私に保証してください。イザベラ・サヨウバ夫人から。
