I.e the ROM, the RAM, the IOModule,\ninterrupt controller etc.\n\nThe IPI block can be outside of the PMU module and be instantiated by the\nboard or perhaps better if we could reuse some of the ZynqMP modules\ninstantiated by the ZCU102 machine to get a CPU-less PS for the PMU\nto interact with. Or something along those lines.\nHow does that sound?\n\nBest regards,\nEdgar","headers":{"Return-Path":"","X-Original-To":"incoming@patchwork.ozlabs.org","Delivered-To":"patchwork-incoming@bilbo.ozlabs.org","Authentication-Results":["ozlabs.org;\n\tspf=pass (mailfrom) smtp.mailfrom=nongnu.org\n\t(client-ip=2001:4830:134:3::11; helo=lists.gnu.org;\n\tenvelope-from=qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org;\n\treceiver=)","ozlabs.org;\n\tdkim=fail reason=\"signature verification failed\" (2048-bit key;\n\tunprotected) header.d=gmail.com header.i=@gmail.com\n\theader.b=\"TLK+TAwS\"; dkim-atps=neutral"],"Received":["from lists.gnu.org (lists.gnu.org [IPv6:2001:4830:134:3::11])\n\t(using TLSv1 with cipher AES256-SHA (256/256 bits))\n\t(No client certificate requested)\n\tby ozlabs.org (Postfix) with ESMTPS id 3yBKpw0MZCz9tYB\n\tfor ;\n\tWed, 11 Oct 2017 01:52:56 +1100 (AEDT)","from localhost ([::1]:35471 helo=lists.gnu.org)\n\tby lists.gnu.org with esmtp (Exim 4.71) (envelope-from\n\t)\n\tid 1e1vtu-0004Ie-76\n\tfor incoming@patchwork.ozlabs.org; Tue, 10 Oct 2017 10:52:54 -0400","from eggs.gnu.org ([2001:4830:134:3::10]:57554)\n\tby lists.gnu.org with esmtp (Exim 4.71)\n\t(envelope-from ) id 1e1vpq-0001jy-LA\n\tfor qemu-devel@nongnu.org; Tue, 10 Oct 2017 10:48:43 -0400","from Debian-exim by eggs.gnu.org with spam-scanned (Exim 4.71)\n\t(envelope-from ) id 1e1vpn-0005ud-Ey\n\tfor qemu-devel@nongnu.org; Tue, 10 Oct 2017 10:48:42 -0400","from mail-lf0-x234.google.com ([2a00:1450:4010:c07::234]:55244)\n\tby eggs.gnu.org with esmtps (TLS1.0:RSA_AES_128_CBC_SHA1:16)\n\t(Exim 4.71) (envelope-from )\n\tid 1e1vpn-0005tK-6v; Tue, 10 Oct 2017 10:48:39 -0400","by mail-lf0-x234.google.com with SMTP id d10so29013013lfg.11;\n\tTue, 10 Oct 2017 07:48:37 -0700 (PDT)","from gmail.com (81-231-233-234-no56.tbcn.telia.com.\n\t[81.231.233.234]) by smtp.gmail.com with ESMTPSA id\n\tz204sm1815883lff.33.2017.10.10.07.48.35\n\t(version=TLS1_2 cipher=ECDHE-RSA-AES128-GCM-SHA256 bits=128/128);\n\tTue, 10 Oct 2017 07:48:35 -0700 (PDT)"],"DKIM-Signature":"v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20161025;\n\th=date:from:to:cc:subject:message-id:references:mime-version\n\t:content-disposition:in-reply-to:user-agent;\n\tbh=x31vu5InvpTLGEogDKkBiQgb1p0lC+p9QyNVzQvvKuo=;\n\tb=TLK+TAwS0nCpgfpbfgv4vr6Vn0gleOq0JSx5jsLPXzBoMcKp1lB5X9iNQvrQBUUWgI\n\tfq1NFVVpYlrhJXuO/sVGnVB+IZo8LZx6PX7wX/aEHTLzxIeoz8f94GcdkZgf8QEmy8fW\n\tIoXkT+IOwXb9hSqs9Fkl9AGQzjJUdq7uaumTT2yiJII5uAvnwEtRKpp8I31J7yL7GMhu\n\tH9YrELuEau3WSHvtz6DywwJOnbggnx9J+YzMZ+cS6CGaIj40TAFCQCDhqWjHdUxn/yTw\n\tLBXQWlgSFbeAjHIx8gZ1qN41GcgvAo6RF2COLKVYHtQsUtdot9asgx6pA47TESgLBQ3j\n\tLudA==","X-Google-DKIM-Signature":"v=1; a=rsa-sha256; c=relaxed/relaxed;\n\td=1e100.net; s=20161025;\n\th=x-gm-message-state:date:from:to:cc:subject:message-id:references\n\t:mime-version:content-disposition:in-reply-to:user-agent;\n\tbh=x31vu5InvpTLGEogDKkBiQgb1p0lC+p9QyNVzQvvKuo=;\n\tb=nkUir0N3cgSSiWc7Gspd5bc8DSzwHiFwCFFRippVEm6iPV6WDeeyv2dt2kfsHk8O4f\n\tFO3/3xme9ykQbMA3QDvAHVhx93Z+McDB6NBKGALrpFQv9FBYgU8QND5xRwQ36einjohK\n\tuYJPYZ9Gxsj9xRY9CLvgMI8t+HKtvnRIdlSj2sb3VTf8YYMSJ1DQL+UZxv1YzbUasUwB\n\tL0fzdBbRrYoeEMHLor8Wm7yJhJ+fTqPscmzMS/MJzPOrNz4Cbmt4BkFK/gUXO1SheLmc\n\t9wfB00SWK5YsZUwMZemhsNtRWLk6fXPCfR8KYEHR7O/NZ4QbuhMBlcPM72Zpw1Ehc/jp\n\tZhTA==","X-Gm-Message-State":"AMCzsaVTWWkNqPtaP3oXXhVrRb+cM7W2fb5xdUcYl0+NDAOeVzY9wccH\n\t9licsrOAmGb3kEd0RirUn74=","X-Google-Smtp-Source":"AOwi7QCbjo1uNGmJkzJ+Zq0O8TlOHNQg0FdRZzG4rnDbqUB6SR/tHmL/APnt8kxYoJfy38FBySgtwg==","X-Received":"by 10.25.222.202 with SMTP id i71mr5533029lfl.177.1507646916302; \n\tTue, 10 Oct 2017 07:48:36 -0700 (PDT)","Date":"Tue, 10 Oct 2017 16:48:34 +0200","From":"\"Edgar E.

The IPI block for example doesn't,\nit belongs outside of the pmu object allthough you will want to instate an\nipi instance in the pmu machine.\n\nHope that helps\nEdgar\n\nSent from my phone","headers":{"Return-Path":"","X-Original-To":"incoming@patchwork.ozlabs.org","Delivered-To":"patchwork-incoming@bilbo.ozlabs.org","Authentication-Results":["ozlabs.org;\n\tspf=pass (mailfrom) smtp.mailfrom=nongnu.org\n\t(client-ip=2001:4830:134:3::11; helo=lists.gnu.org;\n\tenvelope-from=qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org;\n\treceiver=)","ozlabs.org;\n\tdkim=fail reason=\"signature verification failed\" (2048-bit key;\n\tunprotected) header.d=gmail.com header.i=@gmail.com\n\theader.b=\"kStlLvuJ\"; dkim-atps=neutral"],"Received":["from lists.gnu.org (lists.gnu.org [IPv6:2001:4830:134:3::11])\n\t(using TLSv1 with cipher AES256-SHA (256/256 bits))\n\t(No client certificate requested)\n\tby ozlabs.org (Postfix) with ESMTPS id 3yCgBF2F4Hz9sNw\n\tfor ;\n\tFri, 13 Oct 2017 05:59:17 +1100 (AEDT)","from localhost ([::1]:46816 helo=lists.gnu.org)\n\tby lists.gnu.org with esmtp (Exim 4.71) (envelope-from\n\t)\n\tid 1e2ihP-0002Va-GJ\n\tfor incoming@patchwork.ozlabs.org; Thu, 12 Oct 2017 14:59:15 -0400","from eggs.gnu.org ([2001:4830:134:3::10]:42285)\n\tby lists.gnu.org with esmtp (Exim 4.71)\n\t(envelope-from ) id 1e2ih2-0002T4-AN\n\tfor qemu-devel@nongnu.org; Thu, 12 Oct 2017 14:58:53 -0400","from Debian-exim by eggs.gnu.org with spam-scanned (Exim 4.71)\n\t(envelope-from ) id 1e2ih0-0004ti-Sl\n\tfor qemu-devel@nongnu.org; Thu, 12 Oct 2017 14:58:52 -0400","from mail-lf0-x235.google.com ([2a00:1450:4010:c07::235]:46301)\n\tby eggs.gnu.org with esmtps (TLS1.0:RSA_AES_128_CBC_SHA1:16)\n\t(Exim 4.71) (envelope-from )\n\tid 1e2igx-0004oY-IA; Thu, 12 Oct 2017 14:58:47 -0400","by mail-lf0-x235.google.com with SMTP id g70so7014065lfl.3;\n\tThu, 12 Oct 2017 11:58:46 -0700 (PDT)","by 10.25.83.220 with HTTP; Thu, 12 Oct 2017 11:58:43 -0700 (PDT)","by 10.25.83.220 with HTTP; Thu, 12 Oct 2017 11:58:43 -0700 (PDT)"],"DKIM-Signature":"v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20161025;\n\th=mime-version:in-reply-to:references:from:date:message-id:subject:to\n\t:cc; bh=TNwqP7nIFAcqgFlz9/1AhpgrLmK255/8eqJXxtxreas=;\n\tb=kStlLvuJS8aFU01Y9V6myfyavB/P1PDFzsmwyUjuReuTXTKLqYk17cmOxZnY0lre59\n\tZGv/z+UVnTlvUyGW0RhjAVPXcfpjNSADOWmn4L/uYpXwxLMZRIEzaolgwWKf+s/Hpn5z\n\tnD1PtlZJy3gv2yu4sif0TDsfi+cX1DipU2HKXwvUovMPUgkjtO+fR5hedunvN3X0SGO/\n\tevayN8AMJOJPtS2NzwtY1+RqWRVPKxfcGzo/wbekfvjGN+HRzdIKYN3AaaLwm1Fc2FA6\n\tark4THIxpKm/lSJ+LJw1QyXjMPSjNVXdq5m8yjzuCmj7jKWSXhsaehSLebpmd6+0eag9\n\t+NYw==","X-Google-DKIM-Signature":"v=1; a=rsa-sha256; c=relaxed/relaxed;\n\td=1e100.net; s=20161025;\n\th=x-gm-message-state:mime-version:in-reply-to:references:from:date\n\t:message-id:subject:to:cc;\n\tbh=TNwqP7nIFAcqgFlz9/1AhpgrLmK255/8eqJXxtxreas=;\n\tb=bA4IPOv/XdugqYNGzBnYcxP7YJqSfF33PhFfD69fvI+B4Re7NZy4arDYHJ7spRyWmd\n\t9e9MU4BYFqcPyUMvjaZ5D/UunHPAhFQE7SXAQFYugPn4a6T3XV1ED6u1adWTfgzKV5FP\n\tvPresQZMZPYI/XSnAwUo0zrGAWMGqH1OuzwarANC5STlckcUPbksNvQ7nKFVJDGwCweo\n\tECaTUBhLwLarVWrl1e4sqlwNKW2Yeo53vLKFJsg/Dpvw7iEgHV+GctP0cB4o0RvDoJVl\n\tAaJymymU7kSKWu4lbMMbSwizkcIpUIf8pM0Ds8L2GRtxs79SEHsNkuhLPtqhFrH0eOEg\n\tkXEA==","X-Gm-Message-State":"AMCzsaWMkx+mfdB1JOiLjregqA87Pdt6Igl1MQPSfxCRCjF5R4/cgAtg\n\t5BIxtGB1d2pTe9T86aiTZxDDc4TIL4n9Py9lOlg=","X-Google-Smtp-Source":"ABhQp+TeYptZBPySUKIG4DFBT8qa+ND8wR1js+BH9zLuT1darBPgOMpMRXNTmGbnvO88S0neskT4DgAPnf7JxHjL9Vc=","X-Received":"by 10.25.221.196 with SMTP id w65mr949216lfi.89.1507834724615;\n\tThu, 12 Oct 2017 11:58:44 -0700 (PDT)","MIME-Version":"1.0","In-Reply-To":"","References":"\n\t<20171008222029.GA29979@toto>\n\t\n\t<20171010144834.GC5553@toto>\n\t","From":"\"Edgar E.
