<p>Bring virtio_console(4) from FreeBSD. It should help with qemu-guest-agent and probably other things I am not aware of yet.</p>
<p>Once I have patches to test, I'll post them here.</p>

<p>With the recent addition of nvmm, it would be interesting to have something that eases the VM lifecycle, like <code>devel/libvirt</code> . This is a feature request to myself to, at least try to, make <code>devel/libvirt</code> usable with nvmm under DragonFly.</p> DragonFlyBSD - Bug #3205 (Feedback): Go compiler net test failinghttps://bugs.dragonflybsd.org/issues/32052019-09-18T13:28:07ZAnonymous
<p>A recent commit appears to have broken the net test for the Go compiler:<br /><a class="external" href="https://build.golang.org/log/58be31cfd1a92ba9582fdf33e01f79e03184e59b">https://build.golang.org/log/58be31cfd1a92ba9582fdf33e01f79e03184e59b</a></p>

<p>Power usage of a default install is unnecessarily high on current AMD CPUs. Setting the default value of the machdep.cpu_idle_hlt sysctl on these CPUs to 3 by default allows for significant power savings.</p>
<p>I'm not sure how setting machdep.cpu_idle_hlt=3 affects power usage on AMD Family 10h CPUs (e.g. Phenom CPUs).</p>
<p>Some quick benchmarking should be done if possible, to compare the performance difference.</p> DragonFlyBSD - Submit #2721 (Feedback): Some few zalloc calls to objcache ones replacementshttps://bugs.dragonflybsd.org/issues/27212014-08-30T17:12:51Zdclinkdevnexen@gmail.comDragonFlyBSD - Submit #2717 (Feedback): Out of range numeric handlinghttps://bugs.dragonflybsd.org/issues/27172014-08-22T12:36:50Zdclinkdevnexen@gmail.com

<p>This patch is to fix bugs associated with TRIM.</p>
<p>If trim is on as a option, display that when typing "mount".</p>
<p>Change post-trim ffs_blkfree_cg() to use taskqueue_swi_mp and get mp token when modifying freemap.</p>
<p>Make sure TRIM works with softdep. Stash a copy of that vnode's mount point in the ufs inode so that if we are using softdep, we can get access to the mount point through the faked up inode (created in freeblocks). The original mount point path (ip->i_devvp->v_mount->mnt_flag) doesn't have the mount point options.</p>

<p>Hi,</p>
<p>tuxillo noticed that the trick to speedup booting by hitting <enter><br />does not work with default UFS-based installations, as those have no<br />separate /boot partition, and therefore the default location for the<br />loader is wrong (it had been changed to match default HAMMER<br />installations in <a class="changeset" title="boot - Switch boot2 loader path around * Test /loader first, then /boot/loader, makes hitting en..." href="https://bugs.dragonflybsd.org/projects/dragonfly/repository/dragonflybsd/revisions/3735e368a1bdbe773c79c34512f49c905ff77bd7">3735e368a1bdbe773c79c34512f49c905ff77bd7</a>)</p>
<p>We could change boot2 to just continue it's normal operation without<br />entering the prompt when the user hits <enter>. That way one can avoid<br />the delay on UFS and HAMMER systems:</p>

<p>Hi,</p>
<p>there are 3 patches attached:</p>
<p>book.diff - Updates the copyright info relating to FreeBSD at the header<br /> of the handbook.</p>
<p>dfbsd-updating - Update cvsup port path to the current pkgsrc version in<br /> the chapter "Updating DragonFly".</p>
<p>basics.diff - Update various paths relating to pkgsrc and hier(7). Also<br /> make it use the new entity for pkgsrc <br /> tree/collection/framework.</p>
