Just in case. I guess I should test whether this series regresses the use case described in c2cbc38b97; is that correct? I can add that to my todo list, but it won't be quick. I get into building kernels maybe once per quarter :) What repo and branch should I apply this series on top of? ... Actually, I was only CC'd on patch 3/4, so I don't even have the full series. Do you have a public branch somewhere? (If this would mean too much work for you, esp. considering that I'm going to be slow, feel free to go ahead with the patch. Should I find later that something broke, I'll whine then. :) ) Thanks!

FWIW here is a patchwork series [1], just this patch [2] and a tree [3]. [1] https://patchwork.freedesktop.org/series/40778/ [2] https://patchwork.freedesktop.org/patch/213335/ [3] https://github.com/evelikov/linux/commits/ioctl-cleanups > (If this would mean too much work for you, esp. considering that I'm > going to be slow, feel free to go ahead with the patch.

Hence, I'd love it, if anyone who had the original problem can can give this a try. I guess it can wait 1-2 weeks before getting merged, since it won't cause any conflicts ;-) Thanks! Emil

Here's what I did today: (1) Used an up-to-date Fedora 27 VM (kernel 4.15.12-301.fc27.x86_64), with a virtio-gpu display device in the VM config. (2) Fetched your tree at [3]. (3) Seeded ".config" from Fedora's "config-4.15.12-301.fc27.x86_64" and built the kernel with "make binrpm-pkg". This was at: v4.16-rc1-1531-gbefdaafe8b00 For all config related questions asked by "make", I just accepted the defaults. (4) Installed the RPM in the VM and booted it. X didn't come up. I logged in via ssh and saved "dmesg" and "Xorg.0.log". (5) Without touching .config, I checked out the "baseline" of your series, namely: v4.16-rc1-1527-ga7d2a87e99de Built the kernel again with "make binrpm-pkg". (6) In the VM I uninstalled the kernel from (3) and installed the one from (5). X came up successfully. I again saved "dmesg" and "Xorg.0.log". Now I don't know if the dri-devel mailing list strips attachments from emails. I surely won't paste four large text files (without boundaries between them) when what you'll likely want to do is diff them. So, I'm pasting a base64 encoded tarball instead. :) Let me know if I should collect other information or do some experiments. Thanks!

This write-up of events is not precise enough. Instead, I think the timeline is as follows: (1) Commit a325725633c2 ("drm: Lobotomize set_busid nonsense for !pci drivers", 2016-06-21) introduced the regression. By removing drm_virtio_set_busid(), commit a325725633c2 changed the behavior of the following function: > static int drm_set_busid(struct drm_device *dev, struct drm_file *file_priv) > { > struct drm_master *master = file_priv->master; > int ret; > > if (master->unique != NULL) > drm_unset_busid(dev, master); > > if (dev->driver->set_busid) { > ret = dev->driver->set_busid(dev, master); > if (ret) { > drm_unset_busid(dev, master); > return ret; > } > } else { > WARN_ON(!dev->unique); > master->unique = kstrdup(dev->unique, GFP_KERNEL); > if (master->unique) > master->unique_len = strlen(dev->unique); > } > > return 0; > } When a325725633c2 removed drm_virtio_set_busid(), drm_set_busid() started taking the second branch, which wasn't doing the right thing for virtio-vga at the time. (2) There were two ways to fix the regression: either (a) return drm_set_busid() to taking the first branch, or (b) tweak the virtio-vga driver so that the second branch in drm_set_busid() start to behave right. My commit c2cbc38b9715 ("drm: virtio: reinstate drm_virtio_set_busid()", 2016-10-04) implemented (a), by reverting a few chunks of a325725633c2. (3) Gerd thought that approach (b) was superior (and I totally defer to him on this, now that I'm learning of his patches in the first place :) ). Namely, in commit 9785b4321b0b ("drm/virtio: fix busid regression", 2016-11-15), he implemented approach (b), and right after, in commit 1775db074a32 ("Revert "drm: virtio: reinstate drm_virtio_set_busid()"", 2016-11-15), he undid my commit c2cbc38b9715. In other words, Gerd replaced approach (a) with approach (b). (4) Subsequently, commit 5c484cee7ef9 ("drm: Remove drm_driver->set_busid hook", 2017-06-20), changed drm_set_busid() to the following: > static int drm_set_busid(struct drm_device *dev, struct drm_file *file_priv) > { > struct drm_master *master = file_priv->master; > int ret; > > if (master->unique != NULL) > drm_unset_busid(dev, master); > > if (dev_is_pci(dev->dev)) { > ret = drm_pci_set_busid(dev, master); > if (ret) { > drm_unset_busid(dev, master); > return ret; > } > } else { > WARN_ON(!dev->unique); > master->unique = kstrdup(dev->unique, GFP_KERNEL); > if (master->unique) > master->unique_len = strlen(dev->unique); > } > > return 0; > } Perhaps surprisingly, this change did not affect (or "help") virtio-vga at all, despite the fact that drm_virtio_set_busid() also used to call drm_pci_set_busid(). The reason for commit 5c484cee7ef9 not affecting virtio-vga is that the first branch would not be taken just the same, because dev_is_pci() returns false for virtio-vga. (So, the difference with drm_virtio_set_busid() is that drm_virtio_set_busid() would call drm_pci_set_busid() without checking dev_is_pci() first.) Here's the definition of the dev_is_pci() macro, from "include/linux/pci.h": > #define dev_is_pci(d) ((d)->bus == &pci_bus_type) However, the bus type for virtio-vga is "virtio_bus", not "pci_bus_type". Namely, virtio_pci_probe() [drivers/virtio/virtio_pci_common.c] calls register_virtio_device() [drivers/virtio/virtio.c], and there we have > int register_virtio_device(struct virtio_device *dev) > { > int err; > > dev->dev.bus = &virtio_bus; This means that post-5c484cee7ef9, we remain reliant on the second branch in drm_set_busid(), and therefore Gerd's commit 9785b4321b0b, from point (3), should not be backed out. What I could see as justified is a loud comment in drm_virtio_init(), just above the call to drm_dev_set_unique(), explaining why it is necessary to set "unique" manually. The reason is that virtio-vga technically has "virtio_bus", not "pci_bus_type", for bus type, and so the generic PCI BusID-setting will not cover it. Thanks Laszlo

Or to put it in slightly differently: Unlike the other virtual GPU drivers (vmxgfx, qxl, bosh...) virtio abstracts the underlying bus type by using struct virtio_device. Hence the dev_is_pci() check will fail and the unique returned will be the virtio_device' "virtio0", while the "pci:..." one is required. Apart from a beefy comment I've also considered: - Extending the dev_is_pci() case [in drm_set_busid] to consider virtio. It seems like a bigger hack that what we have currently. - point drm_device::dev to the parent of the virtio_device The biggest hack imaginable, if even possible. Above said, consider patches 3+4 dropped and I'll follow-up with a patch adding inline documentation about this. Thank you very much for the help. Emil P.S. On the plus side, I am working on a X/modesetting series that removes all the mess which requires this workaround ;-)

You can also see that in sysfs: root@fedora ~# readlink /sys/class/drm/card0 ../../devices/pci0000:00/0000:00:01.0/virtio0/drm/card0 ^^^^^^^ extra level here. That is the reason why drm_virtio_init() goes lookup the parent device, checks if it happens to be pci, if so use the parent device to construct the "pci:..." unique id for the virtio device (and also use the pci device ressources to kick out the firmware framebuffer). cheers, Gerd

Why is this a hack? It _feels_ very hacky to reach/store the parent of the _parent_ device given. Dummy grep for \<dev\> showed hundreds of entries, but many of those are unrelated.
