When the serial port is available, use the UEFI driver instead of direct io-port accesses to avoid conflicts between the firmware and direct hardware access, as happens on Hyper-V (Azure) setups. This change enables efiserialio to be built for efi-amd64 and has higher order priority vs comconsole, and only uses efiserialio if the hypervisor is Hyper-V. When efiserialio successfully probes, it will set efi_comconsole_avail=3Dtrue which will prevent comconsole from probing in this setup.

I cannot give any definitive information, and know nothing about Home Assistant OS but I see a problem with your reasoning here, you're comparing CPU usage with system load, which is apples to oranges; they are measuring two different things (albeit related to each other). It is quite possible to have a relatively high load with low CPU usage, in fact I think I can see that happen when using virtual machines, since they also have to handle their own internal interrupts and the like and will be often ready to run, adding to the load, but actually doing very little CPU work. So you should compare load to load and CPU usage to CPU usage. In relation to a raspberry I expect load to not be significantly lower for this kind of work, but actual CPU usage to be noticeably lower, but not near zero. > > What's wrong?

ZFS is going to add some load too, since it is a very complex filesystem and does a lot of work behind the scenes. Especially if you're using file system compression. -- Guido Falsi From nobody Sat Mar 18 16:29:08 2023 X-Original-To: freebsd-virtualization@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4Pf5zs3BWlz3ylbd for ; Sat, 18 Mar 2023 16:29:13 +0000 (UTC) (envelope-from mad@madpilot.net) Received: from mail.madpilot.net (vogon.madpilot.net [159.69.1.99]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256) (Client did not present a certificate) by mx1.freebsd.org (Postfix) with ESMTPS id 4Pf5zr2Wz5z3Grn for ; Sat, 18 Mar 2023 16:29:12 +0000 (UTC) (envelope-from mad@madpilot.net) Authentication-Results: mx1.freebsd.org; dkim=pass header.d=madpilot.net header.s=bjowvop61wgh header.b="J pqiVV3"; spf=pass (mx1.freebsd.org: domain of mad@madpilot.net designates 159.69.1.99 as permitted sender) smtp.mailfrom=mad@madpilot.net; dmarc=pass (policy=quarantine) header.from=madpilot.net Received: from mail (mail [192.168.254.3]) by mail.madpilot.net (Postfix) with ESMTP id 4Pf5zq0r6Jz6ddR; Sat, 18 Mar 2023 17:29:11 +0100 (CET) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d=madpilot.net; h= content-transfer-encoding:content-type:content-type:in-reply-to :content-language:references:from:from:subject:subject:date:date :message-id:received; s=bjowvop61wgh; t=1679156949; x= 1680971350; bh=SMD/qVztp//05j+/VTM3S5YSooYMu/BgjEiBMbKlCJA=; b=J pqiVV3LG8dIteNDDX28wrrcvDXQWiIzkKYHkv5KfPbW3j1QS8nspPvSz3K/xPh3k c3JjKMt5ETJtjOQSQ5FyKOlSUHlxBnYNK5rUg+lr2VzXns0poUUnlWtKuGaPapYh ggct600x2x8F9T2JEP6lAiayqEUodid2MLO5RHPT+MGReJJabf73xYLtzATK3NXC I8IFl3qVNFkcacR9cVoq/baLyliaEeIZLqM6toLls5vJ8fyqq8ma4dbL/u2hN0JL hob7HMv/2AGpJQx8njaIIcyY7YMWlcd+FRT87YKvn3eiEJw2Qnnfwp8GG6FBXcGv 2xnXrc5TGp5Aeaxta1sZQ== Received: from mail.madpilot.net ([192.168.254.3]) by mail (mail.madpilot.net [192.168.254.3]) (amavisd-new, port 10026) with ESMTP id QHE3BBPuSzwj; Sat, 18 Mar 2023 17:29:09 +0100 (CET) Message-ID: <80da3a32-4c4c-5135-88b5-99419709ede9@madpilot.net> Date: Sat, 18 Mar 2023 17:29:08 +0100 Subject: Re: Bhyve process consumes way too much CPU From: Guido Falsi To: =?UTF-8?Q?Julie_Koubov=c3=a1?= , freebsd-virtualization@freebsd.org References: Content-Language: en-US In-Reply-To: Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 8bit X-Spamd-Result: default: False [-1.99 / 15.00]; MISSING_MIME_VERSION(2.00)[]; NEURAL_HAM_LONG(-1.00)[-1.000]; NEURAL_HAM_MEDIUM(-1.00)[-1.000]; NEURAL_HAM_SHORT(-0.99)[-0.992]; DMARC_POLICY_ALLOW(-0.50)[madpilot.net,quarantine]; R_SPF_ALLOW(-0.20)[+mx]; R_DKIM_ALLOW(-0.20)[madpilot.net:s=bjowvop61wgh]; MIME_GOOD(-0.10)[text/plain]; RCVD_TLS_LAST(0.00)[]; MLMMJ_DEST(0.00)[freebsd-virtualization@freebsd.org]; FROM_EQ_ENVFROM(0.00)[]; MIME_TRACE(0.00)[0:+]; ARC_NA(0.00)[]; TO_MATCH_ENVRCPT_SOME(0.00)[]; DKIM_TRACE(0.00)[madpilot.net:+]; FROM_HAS_DN(0.00)[]; RCPT_COUNT_TWO(0.00)[2]; TO_DN_SOME(0.00)[]; ASN(0.00)[asn:24940, ipnet:159.69.0.0/16, country:DE]; RCVD_COUNT_THREE(0.00)[3]; MID_RHS_MATCH_FROM(0.00)[] X-Rspamd-Queue-Id: 4Pf5zr2Wz5z3Grn X-Spamd-Bar: - X-ThisMailContainsUnwantedMimeParts: N List-Id: Discussion List-Archive: https://lists.freebsd.org/archives/freebsd-virtualization List-Help: List-Post: List-Subscribe: List-Unsubscribe: Sender: owner-freebsd-virtualization@freebsd.org X-BeenThere: freebsd-virtualization@freebsd.org On 18/03/23 17:14, Guido Falsi wrote: > On 18/03/23 14:59, Julie Koubová wrote: >> Hey everyone, >> >> I'm running Linux (Home Assistant OS) in Bhyve on FreeBSD 13.1.

BTW, I forgot to mention that any load average less than the number of available threads means the machine is not fully loaded, so 0.50 for a 4 CPU, 8 threads machine is quite low by any measurements, while 0.50 on a machine with half the available CPUs/threads means double the actual load for that hardware. That should be accounted too. -- Guido Falsi
