[PATCH v3 00/14] Provide core infrastructure for managing open/release
by Jason Gunthorpe 05 Aug '21

05 Aug '21

This is in support of Max's series to split vfio-pci. For that to work the reflck concept embedded in vfio-pci needs to be sharable across all of the new VFIO PCI drivers which motivated re-examining how this is implemented. Another significant issue is how the VFIO PCI core includes code like: if (pci_dev_driver(pdev) != &vfio_pci_driver) Which is not scalable if there are going to be multiple different driver types. This series takes the approach of moving the "reflck" mechanism … [View More]into the core code as a "device set". Each vfio_device driver can specify how vfio_devices are grouped into the set using a key and the set comes along with a set-global mutex. The core code manages creating per-device set memory and associating it with each vfio_device. In turn this allows the core code to provide an open/close_device() operation that is called only for the first/last FD, and is called under the global device set lock. Review of all the drivers show that they are either already open coding the first/last semantic or are buggy and missing it. All drivers are migrated/fixed to the new open/close_device ops and the unused per-FD open()/release() ops are deleted. The special behavior of PCI around the bus/slot "reset group" is recast in terms of the device set which conslidates the reflck, eliminates two touches of pci_dev_driver(), and allows the reset mechanism to share across all VFIO PCI drivers. PCI is changed to acquire devices directly from the device set instead of trying to work backwards from the struct pci_device. Overall a few minor bugs are squashed and quite a bit of code is removed through consolidation. v3: - Atomic conversion of mbochs_used_mbytes - Add missing vfio_uninit_group_dev in error unwind of mbochs - Reorganize vfio_assign_device_set() - Move the dev_set_list hunks to the introduction of the dev_set - Use if instead of ?: in fsl - Add a comment about the whole bus reset in vfio_pci_probe() - Rename vfio_pci_check_all_devices_bound() to vfio_pci_is_device_in_set() - Move logic from vfio_pci_try_bus_reset() into vfio_pci_find_reset_target() v2: https://lore.kernel.org/r/0-v2-b6a5582525c9+ff96-vfio_reflck_jgg@nvidia.com - Reorder fsl and mbochs vfio_uninit_group_dev - Fix missing error unwind in mbochs - Return 0 from mdev open_device if there is no op - Fix style for else {} - Spelling fix for singleton - Acquire cur_mem under lock - Always use error unwind flow for vfio_pci_check_all_devices_bound() v1: https://lore.kernel.org/r/0-v1-eaf3ccbba33c+1add0-vfio_reflck_jgg@nvidia.com Jason Gunthorpe (12): vfio/samples: Remove module get/put vfio/mbochs: Fix missing error unwind of mbochs_used_mbytes vfio: Provide better generic support for open/release vfio_device_ops vfio/samples: Delete useless open/close vfio/fsl: Move to the device set infrastructure vfio/platform: Use open_device() instead of open coding a refcnt scheme vfio/pci: Change vfio_pci_try_bus_reset() to use the dev_set vfio/pci: Reorganize VFIO_DEVICE_PCI_HOT_RESET to use the device set vfio/mbochs: Fix close when multiple device FDs are open vfio/ap,ccw: Fix open/close when multiple device FDs are open vfio/gvt: Fix open/close when multiple device FDs are open vfio: Remove struct vfio_device_ops open/release Max Gurtovoy (1): vfio: Introduce a vfio_uninit_group_dev() API call Yishai Hadas (1): vfio/pci: Move to the device set infrastructure Documentation/driver-api/vfio.rst | 4 +- drivers/gpu/drm/i915/gvt/kvmgt.c | 8 +- drivers/s390/cio/vfio_ccw_ops.c | 8 +- drivers/s390/crypto/vfio_ap_ops.c | 8 +- drivers/vfio/fsl-mc/vfio_fsl_mc.c | 159 +----- drivers/vfio/fsl-mc/vfio_fsl_mc_intr.c | 6 +- drivers/vfio/fsl-mc/vfio_fsl_mc_private.h | 7 - drivers/vfio/mdev/vfio_mdev.c | 31 +- drivers/vfio/pci/vfio_pci.c | 487 +++++++----------- drivers/vfio/pci/vfio_pci_private.h | 7 - drivers/vfio/platform/vfio_platform_common.c | 86 ++-- drivers/vfio/platform/vfio_platform_private.h | 1 - drivers/vfio/vfio.c | 144 +++++- include/linux/mdev.h | 9 +- include/linux/vfio.h | 26 +- samples/vfio-mdev/mbochs.c | 40 +- samples/vfio-mdev/mdpy.c | 40 +- samples/vfio-mdev/mtty.c | 40 +- 18 files changed, 468 insertions(+), 643 deletions(-) -- 2.32.0 [View Less]

[PATCH] drm/aperture: Pass DRM driver structure instead of driver name
by Thomas Zimmermann 05 Aug '21

05 Aug '21

Print the name of the DRM driver when taking over fbdev devices. Makes the output to dmesg more consistent. Note that the driver name is only used for printing a string to the kernel log. No UAPI is affected by this change.

Help needed for EVoC/GSoC/Outreachy
by Lyude Paul 05 Aug '21

05 Aug '21

Hi! As some of you might already be aware, after helping out X.org project the previous years with regards to student outreach, Trevor decided to retire from this position in hopes that someone else will be able to step up and take on these responsibilities. As such, we're trying to find people who would be willing to volunteer their time to help out with getting us involved once again in student outreach programs. In the past, X.org has been active in the GSoC program, occasionally Outreachy, … [View More]and our own EVoC program. As of 2021 though, GSoC decided to shorten the amount of time allocated for a student to work on their project. This unfortunately posed some problems for X.org/freedesktop.org as a lot of the potential work that would have been good for us to have students working on wouldn't really fit within the new GSoC timeframe. While it's certainly possible that there will be projects that come up in the future which do fit into this new timeline, we think it'd be a good idea to step up our involvement again with Outreachy where the program is a good bit more flexible then GSoC. We've also had pretty good experience working with the Outreachy candidates we've had in the past. The other main topic of discussion is around the fact that our own program, EVoC, hasn't really had anyone available to volunteer to help run it for a while now. For those who aren't aware, EVoC is a program similar to Google Summer of Code that X.org started running with much more relaxed requirements then GSoC/Outreachy in order to help fill the gaps for any exceptional cases with students who would otherwise be left out by the requirements for GSoC/Outreachy. Typically though, EVoC is usually considered the last resort after a student has tried getting into GSoC/Outreachy. So, the two biggest things that we need are: * Admin volunteer(s) * Mentors, mentors, mentors! We really need these the most. So, what responsibilities would being an admin for this entail? * Fielding questions from potential GSoC/EVoC/Outreachy participants. Most of these students are just looking for simple details of how these programs work and are looking for project ideas. Responding to these inquiries is mostly just a matter of pointing students to various pages on our wiki or replying with form/stock replies. Most of the students at this phase expect to be handed a project and a mentor, and therefore end up learning that they will need to come up with their own project and mentor. * For the small handful of students that make it to the next phase and figure out a project idea, they then need to find a mentor. Usually the admin will help out by taking a look at who proposed the project idea, and/or looking through commit messages and mailing list history to try to find someone who would be a good fit and willing to mentor the student. Sometimes this happens quickly, and sometimes it requires poking a lot of people - and occasionally, there might not always be a mentor to be found. * If we have a student, project, and mentor then the next step is having the student write up a proposal. Many students start out with over-simplified proposals, so a lot of this work is just gently nudging students and getting them to refine their work items into a week-by-week synopsis. There's usually a good bit of back and forth with the student's proposal, and occasionally the mentor may be involved with this step. * The admin then works with the student to come up with a timeline for their work, taking into account any vacation time the student may have, along with coordinating the frequency/type of meetings that will happen between the student and the mentor. If the mentor is unable to attend all of these meetings, it's usually up to the admin to check in with the student to see how they are progressing and potentially provide them tips if they get stuck. As for being a mentor, it's pretty much as simple as it sounds: you work with students who have projects to help familiarize them with the project at hand, help them out wherever needed, check in on their progress, and guide them along the way towards reaching their project goal along with grading their work. Please help spread the word on this, and contact anyone you know who might be involved with this! We'll be happy to provide more information on how you can get started. Remember, folks like myself wouldn't be in this community without projects like GSoC :). -- Cheers, Lyude Paul (she/her) Software Engineer at Red Hat [View Less]
