I would like to remind you that reports are collected during the last month of every quarter. Status report submissions do not need to be very long. They may be about anything happening in the FreeBSD project and community, and they provide a great way to inform FreeBSD users and developers about work that is underway or has been completed. Report submissions are not limited to committers; anyone doing anything interesting and FreeBSD related can -- and should -- write one! The preferred method is to follow the guidelines at the Quarterly GitHub repository: https://github.com/freebsd/freebsd-quarterly Alternatively you can fetch the Markdown template, fill it in, and email it to quarterly-submissions@FreeBSD.org. The template can be found at: https://raw.githubusercontent.com/freebsd/freebsd-quarterly/master/report-sample.md We look forward to seeing your 2020Q2 reports! Thanks, Daniel Ebdrup Jensen (on behalf of quarterly@) _______________________________________________ freebsd-quarterly-calls@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-quarterly-calls To unsubscribe, send any mail to "freebsd-quarterly-calls-unsubscribe@freebsd.org" From owner-freebsd-hackers@freebsd.org Mon Jun 29 19:20:15 2020 Return-Path: Delivered-To: freebsd-hackers@mailman.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mailman.nyi.freebsd.org (Postfix) with ESMTP id 18868352AEF; Mon, 29 Jun 2020 19:20:15 +0000 (UTC) (envelope-from thj@freebsd.org) Received: from wforward1-smtp.messagingengine.com (wforward1-smtp.messagingengine.com [64.147.123.30]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client did not present a certificate) by mx1.freebsd.org (Postfix) with ESMTPS id 49wcl253RJz4GWL; Mon, 29 Jun 2020 19:20:14 +0000 (UTC) (envelope-from thj@freebsd.org) Received: from compute7.internal (compute7.nyi.internal [10.202.2.47]) by mailforward.west.internal (Postfix) with ESMTP id A814FA29; Mon, 29 Jun 2020 15:20:12 -0400 (EDT) Received: from mailfrontend2 ([10.202.2.163]) by compute7.internal (MEProxy); Mon, 29 Jun 2020 15:20:12 -0400 DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d= messagingengine.com; h=content-type:date:from:message-id :mime-version:subject:to:x-me-proxy:x-me-proxy:x-me-sender :x-me-sender:x-sasl-enc; s=fm3; bh=XSYK2hekvrTOPWxhst886uksaep4J QkgR4yNUGo4KX4=; b=ULPKQVYYqNSD/ZsjsrKJYOEaMzcvT/9QMASJv0s/KYJ08 X3qJEWGRHqIxKsOYzKRbzLloqWwhISbEEFVx7K7Erg5S3AckZb1USWzTKH2HMX0S ++/TWfLKLfIFfnw0/Ggk7CyJ+9xX4A95FyOTDU3D8g6PqP2/ftVTyBVJ21iZWPOH vDgkoJrgEiQKeRVqHtNUfcP5fmx6BR+pZi5YM+tWV1TBVXIpwOungVfnJqvbMyFI gIiu+HZeidbIMLaJKT98muwwSafB+g47jfrC8ZKhuwsS2lkrBehq1tGKUnODeYiR Kk/JtAs/X6tmV2KNgi/+FBtKm2ZVtG3IKZ0ew5C+Q== X-ME-Sender: X-ME-Proxy-Cause: gggruggvucftvghtrhhoucdtuddrgeduhedrudelledgieefucetufdoteggodetrfdotf fvucfrrhhofhhilhgvmecuhfgrshhtofgrihhlpdfqfgfvpdfurfetoffkrfgpnffqhgen uceurghilhhouhhtmecufedttdenucgoufhorhhtvggutfgvtghiphdvucdlgedtmdenuc fjughrpeffhffvuffkgggtugesthdtredttddtvdenucfhrhhomhepvfhomhculfhonhgv shcuoehthhhjsehfrhgvvggsshgurdhorhhgqeenucggtffrrghtthgvrhhnpeehhffhhf ffveeihfeiteeuffduveevieefudfgheelieekieevgfdtgeeuteeludenucffohhmrghi nhepghhoohhglhgvrdgtohhmpdhfrhgvvggsshgurdhorhhgpdgrughvvghnthhurhhish htrdhmvgenucfkphepudefjedrhedtrddujedruddvnecuvehluhhsthgvrhfuihiivgep tdenucfrrghrrghmpehmrghilhhfrhhomhepthhhjhesfhhrvggvsghsugdrohhrgh X-ME-Proxy: Received: from tom-desk.erg.abdn.ac.uk (tom-desk.erg.abdn.ac.uk [137.50.17.12]) by mail.messagingengine.com (Postfix) with ESMTPA id 2BFF73067CC7; Mon, 29 Jun 2020 15:20:11 -0400 (EDT) Date: Mon, 29 Jun 2020 20:17:51 +0100 From: Tom Jones To: freebsd-hackers@freebsd.org, freebsd-announce@freebsd.org, freebsd-advocacy@freebsd.org Subject: Virtual Bug Squash, Saturday 11th July 1400-2100UTC Message-ID: <20200629191751.GA27264@tom-desk.erg.abdn.ac.uk> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline X-Rspamd-Queue-Id: 49wcl253RJz4GWL X-Spamd-Bar: / Authentication-Results: mx1.freebsd.org; none X-Spamd-Result: default: False [0.00 / 15.00]; local_wl_from(0.00)[freebsd.org]; ASN(0.00)[asn:11403, ipnet:64.147.123.0/24, country:US] X-BeenThere: freebsd-hackers@freebsd.org X-Mailman-Version: 2.1.33 Precedence: list List-Id: Technical Discussions relating to FreeBSD List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 29 Jun 2020 19:20:15 -0000 Hello Everyone, On the 11th July 2020 from 1400-2100 UTC we will be running a coordinated virtual Bug Squash. FreeBSD has a Problem Report (PR) database[1] where users and developers are encouraged to file issues and regressions they find in both the base system and ports tree. A Bug Squash is a focused session where we try to triage, process, fix and close as many reports as we can from the PR database. This July 11th Bug Squash we will focus on closing as many PRs with patches as we can, some rationale for this is written up here[4]. While we do process and close issues there are a large number of PRs with patches attached that should be processed. At the time of writing there are: - all base system PRs with patches (639)[2] - all base system PRs with patches, but assigned to no one (277)[3] We will host a google meet at the start of the Bug Squash to provide an introduction to the process and will use the #freebsd-bugs irc channel on freenode to coordinate work, triage and discuss PRs and patches. https://meet.google.com/dfp-fsou-pwi We look forward to joining you to squash bugs and commit fixes. - Tom and Allan Some other links: https://wiki.freebsd.org/OfficeHours https://wiki.freebsd.org/MarkLinimon/BugbustingOfficeHours https://wiki.freebsd.org/Bugathons https://wiki.freebsd.org/MarkLinimon/KitchenerNotes https://wiki.freebsd.org/BugBusting https://adventurist.me/posts/00301 [1]: https://bugs.freebsd.org [2]: https://bugs.freebsd.org/bugzilla/buglist.cgi?keywords=patch%2C%20&keywords_type=allwords&limit=0&list_id=296749&order=bug_id%20DESC&product=Base%20System&query_format=advanced&resolution=--- [3]: https://bugs.freebsd.org/bugzilla/buglist.cgi?email1=bugs%40FreeBSD.org&emailassigned_to1=1&emailtype1=substring&keywords=patch%2C%20&keywords_type=allwords&list_id=296748&product=Base%20System&query_format=advanced&resolution=--- [4]: https://wiki.freebsd.org/Bugathons/PRsWithPatches From owner-freebsd-hackers@freebsd.org Tue Jun 30 18:12:13 2020 Return-Path: Delivered-To: freebsd-hackers@mailman.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mailman.nyi.freebsd.org (Postfix) with ESMTP id 758AE352D08 for ;

It does support NVMe device emulation in bhyve, but based on loading RDMA drivers above, I'm guessing this won't meet your needs. Another option would be to use the nvmf_tgt provided in SPDK (https://spdk.io/). This would give you the similar functionality to the Linux NVMe target and supports multiple transports including RoCE. --chuck From owner-freebsd-hackers@freebsd.org Wed Jul 1 05:47:44 2020 Return-Path: Delivered-To: freebsd-hackers@mailman.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mailman.nyi.freebsd.org (Postfix) with ESMTP id EAF7836295D for ; Wed, 1 Jul 2020 05:47:44 +0000 (UTC) (envelope-from ekraju@gmail.com) Received: from mail-yb1-xb44.google.com (mail-yb1-xb44.google.com [IPv6:2607:f8b0:4864:20::b44]) (using TLSv1.3 with cipher TLS_AES_128_GCM_SHA256 (128/128 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256 client-signature RSA-PSS (2048 bits) client-digest SHA256) (Client CN "smtp.gmail.com", Issuer "GTS CA 1O1" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 49xVcc1Jvgz3gL1 for ; Wed, 1 Jul 2020 05:47:43 +0000 (UTC) (envelope-from ekraju@gmail.com) Received: by mail-yb1-xb44.google.com with SMTP id y13so11359607ybj.10 for ; Tue, 30 Jun 2020 22:47:43 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20161025; h=mime-version:references:in-reply-to:from:date:message-id:subject:to :cc; bh=fQlxWz0P/ba1ZCC+mWhdlnON4KyNT84ZFX4MQAdtyLU=; b=Hhbfe6/W2E2DVyQQ4bZPV0WNKZJlibT/JQOdYao7vNvYnQYV6olzUsGF+ImQ47blYr xgH3d0b00iX3BPDr7yMbqwkkvTXnaBWKrdm7MwnnhQ49wE7PZg6zTZHDfrkazWWZv+cn VjSU6UvrXVcE/LMP9olS8HzBm7j8UZGF3HMngkAcIiiLVUpgMSHWtovX0RQnga5mkKM5 F54De1slwZxlh2K3zOAKYl4bst4JjQ2xKASgp3tvQ8scmP0/4bJShcRoBaB0bQLErNFb B3Fy4eO37091x+33UwHTcupzsO0CCwxUO6uVhHFWuXeL49bpEJZbALmYurQHIu5QJGLc n77Q== X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20161025; h=x-gm-message-state:mime-version:references:in-reply-to:from:date :message-id:subject:to:cc; bh=fQlxWz0P/ba1ZCC+mWhdlnON4KyNT84ZFX4MQAdtyLU=; b=I7Pfrjrl6irFG/rnVvXBebA/iG4MbWanSCM6/GgMJ5G5jOHbEeEx3MSlakHbWgUB98 6gCSQj7mcs9eeCUo+uUfPY+WopZi5asmPy4QnWGCIIEcUnxzMFV96J1Stil6SEtXK5a3 vafFaXoV8tMh0qzDiH4RA8BIHF4AC9ip4hQP67w3zVp01ysyKCrlMyv/7++SVYxw9q8Q sHbp4KkVHv2VpAUbxGyMrl6GVVK2EZnS28XBsY20o3JBD22lr+A+M0LkexF4VN5jj3zm X+nf5kmZXjjPMznxImZlk9iS7ZA99E1WHYE5wSccflVgCMPEx1YYNw6eY+/bYriEwgZI Ky6Q== X-Gm-Message-State: AOAM532usEuomGkxnWm0jSbAriYvJGUDCJ2Y4Tg93+cb36WSwD+rlrA7 bxtRpr97v5KNOmkrl/0CL8uCVRwfwIxctB4NHqx1qdPA X-Google-Smtp-Source: ABdhPJxSxCxQuMMkAdDb1N/aWzSxUDk574BiUrR8nRMDzzFTUuTNOhtmyAYbudnGjIGXOonFxlPjz15HyCX4T93DwEA= X-Received: by 2002:a25:1f55:: with SMTP id f82mr41134205ybf.103.1593582463280; Tue, 30 Jun 2020 22:47:43 -0700 (PDT) MIME-Version: 1.0 References: In-Reply-To: From: Krishnamraju Eraparaju Date: Wed, 1 Jul 2020 11:17:32 +0530 Message-ID: Subject: Re: how to set up a nvme target over RAMDISK backend To: Chuck Tuffli Cc: FreeBSD Hackers X-Rspamd-Queue-Id: 49xVcc1Jvgz3gL1 X-Spamd-Bar: -- Authentication-Results: mx1.freebsd.org; dkim=pass header.d=gmail.com header.s=20161025 header.b=Hhbfe6/W; dmarc=pass (policy=none) header.from=gmail.com; spf=pass (mx1.freebsd.org: domain of ekraju@gmail.com designates 2607:f8b0:4864:20::b44 as permitted sender) smtp.mailfrom=ekraju@gmail.com X-Spamd-Result: default: False [-2.78 / 15.00]; ARC_NA(0.00)[]; NEURAL_HAM_MEDIUM(-0.98)[-0.980]; R_DKIM_ALLOW(-0.20)[gmail.com:s=20161025]; FROM_HAS_DN(0.00)[]; FREEMAIL_FROM(0.00)[gmail.com]; R_SPF_ALLOW(-0.20)[+ip6:2607:f8b0:4000::/36]; MIME_GOOD(-0.10)[multipart/alternative,text/plain]; PREVIOUSLY_DELIVERED(0.00)[freebsd-hackers@freebsd.org]; NEURAL_HAM_LONG(-1.01)[-1.013]; NEURAL_SPAM_SHORT(0.22)[0.216]; TO_MATCH_ENVRCPT_SOME(0.00)[]; TO_DN_ALL(0.00)[]; DKIM_TRACE(0.00)[gmail.com:+]; RCPT_COUNT_TWO(0.00)[2]; RCVD_IN_DNSWL_NONE(0.00)[2607:f8b0:4864:20::b44:from]; DMARC_POLICY_ALLOW(-0.50)[gmail.com,none]; FROM_EQ_ENVFROM(0.00)[]; MIME_TRACE(0.00)[0:+,1:+,2:~]; FREEMAIL_ENVFROM(0.00)[gmail.com]; ASN(0.00)[asn:15169, ipnet:2607:f8b0::/32, country:US]; RCVD_COUNT_TWO(0.00)[2]; RCVD_TLS_ALL(0.00)[]; DWL_DNSWL_NONE(0.00)[gmail.com:dkim] Content-Type: text/plain; charset="UTF-8" X-Content-Filtered-By: Mailman/MimeDel 2.1.33 X-BeenThere: freebsd-hackers@freebsd.org X-Mailman-Version: 2.1.33 Precedence: list List-Id: Technical Discussions relating to FreeBSD List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 01 Jul 2020 05:47:45 -0000 Thank you very much Chuck!

You have to connect to the gdb backend over the serial port using kgdb running on a different system after you see the "Switching to gdb ..." message. Then debug as usual and detach when done.

I have one more silly question. I have a terminal at ttyu1 and I can login through telnet and it works fine except when I issue "sysctl debug.kdb.enter=1" it hangs showing "debug.kdb.enter". I have checked the freebsd handbook. At it is mentioned in chapter 26.6, I tried to put "device sio" in my Kern Conf and it gives me build failure. Looking at the build log it seems it is missing some header file while building dev/sio.c. Basically I tried to get into db from serial console and failed. One more thing is in the console after I get into db and launched gdb I have also tried connecting kgdb from another host, but got timeout while connecting the target.

We=E2=80=99ll be holding two = sessions, one timed well for Europe and the Americas; the other timed = well for Asia, Africa and India. Sessions will be held at 1800 UTC on = July 7, 2020 and 0200 UTC on July 8, 2020. See = https://wiki.freebsd.org/OfficeHours for details on how to join either a = live stream to watch, or an interactive meeting to participate. A link = to this agenda (and any updates) will be there as well. We=E2=80=99ll be discussing the following topics and taking general = questions at the end. We=E2=80=99ll have a moderator who will help call = on people in the meeting to ask questions (or to offer comments) as well = as relay relevant questions from IRC. =E2=80=A2 Introduce core members -- All the core team members in = attendance will briefly introduce themselves and say a few words about = their goals for this core term. =E2=80=A2 Discuss proposed terminology changes -- Recently, the = prior core team had sent out a proposal about how to handle shifts in = language based on societal change. The initial message was poorly = written and didn=E2=80=99t strike the right tone. We=E2=80=99ll discuss = it, the underlying issue and how the new core team plans on doing things = better. =E2=80=A2 Recruiting for project teams -- When a new core team = takes over, it=E2=80=99s a good time to assess the needs of each of the = teams that we have running different aspects of the project, such as = administering our machines and helping keep FreeBSD secure. One common = theme is the need for more help. We=E2=80=99ll discuss what teams there = are, and make a recruiting pitch and answer any questions. =E2=80=A2 Core TODO List publishing -- To continue the openness = initiative, the core team will start publishing out TODO list. This will = be in addition to the normal meeting minutes and other openness ideas. = The new core team would love to hear from the community how to improve = our communications. =E2=80=A2 Git Transition -- To raise awareness, Ed Maste and = Warner Losh will be giving a brief presentation about the state of the = project=E2=80=99s planned transition to git. They can answer a few = questions here, but are also planning an entire office hours on the git = transition (tentatively scheduled in two weeks). =E2=80=A2 General Questions -- Time permitting, the new core = team can answer any other questions or concerns the community might = have.

Sessions will be held at 1800 UTC on = July 7, 2020 and 0200 UTC on July 8, 2020. See = https://wiki.freebsd.org/OfficeHours for details on how to join either a = live stream to watch, or an interactive meeting to participate. A link = to this agenda (and any updates) will be there as well. We=E2=80=99ll be discussing the following topics and taking general = questions at the end. We=E2=80=99ll have a moderator who will help call = on people in the meeting to ask questions (or to offer comments) as well = as relay relevant questions from IRC. =E2=80=A2 Introduce core members -- All the core team members in = attendance will briefly introduce themselves and say a few words about = their goals for this core term. =E2=80=A2 Discuss proposed terminology changes -- Recently, the = prior core team had sent out a proposal about how to handle shifts in = language based on societal change. The initial message was poorly = written and didn=E2=80=99t strike the right tone. We=E2=80=99ll discuss = it, the underlying issue and how the new core team plans on doing things = better. =E2=80=A2 Recruiting for project teams -- When a new core team = takes over, it=E2=80=99s a good time to assess the needs of each of the = teams that we have running different aspects of the project, such as = administering our machines and helping keep FreeBSD secure. One common = theme is the need for more help. We=E2=80=99ll discuss what teams there = are, and make a recruiting pitch and answer any questions. =E2=80=A2 Core TODO List publishing -- To continue the openness = initiative, the core team will start publishing out TODO list. This will = be in addition to the normal meeting minutes and other openness ideas. = The new core team would love to hear from the community how to improve = our communications. =E2=80=A2 Git Transition -- To raise awareness, Ed Maste and = Warner Losh will be giving a brief presentation about the state of the = project=E2=80=99s planned transition to git. They can answer a few = questions here, but are also planning an entire office hours on the git = transition (tentatively scheduled in two weeks). =E2=80=A2 General Questions -- Time permitting, the new core = team can answer any other questions or concerns the community might = have.
