[PATCH] utils: add glibc version checking for uadk_memcpy
by Kai Ye 25 Mar '22

25 Mar '22

No assembly language is required as glibc version >= 2.32. This is because the later glibc version has updated this optimization.

Fw:[PATCH RFC 00/12] IOMMUFD Generic interface

It takes over from drivers/vfio/vfio_iommu_type1.c (aka the VFIO container) which is the VFIO specific interface for a similar idea. We see a broad need for extended features, some being highly IOMMU device specific:  - Binding iommu_domain's to PASID/SSID  - Userspace page tables, for ARM, x86 and S390  - Kernel bypass'd invalidation of user page tables  - Re-use of the KVM page table in the IOMMU  - Dirty page tracking in the IOMMU  - Runtime Increase/Decrease of IOPTE size  - PRI support with faults resolved in userspace As well as a need to access these features beyond just VFIO, VDPA for instance, but other classes of accelerator HW are touching on these areas now too. The v1 series proposed re-using the VFIO type 1 data structure, however it was suggested that if we are doing this big update then we should also come with a data structure that solves the limitations that VFIO type1 has. Notably this addresses:  - Multiple IOAS/'containers' and multiple domains inside a single FD  - Single-pin operation no matter how many domains and containers use    a page  - A fine grained locking scheme supporting user managed concurrency for    multi-threaded map/unmap  - A pre-registration mechanism to optimize vIOMMU use cases by    pre-pinning pages  - Extended ioctl API that can manage these new objects and exposes    domains directly to user space  - domains are sharable between subsystems, eg VFIO and VDPA The bulk of this code is a new data structure design to track how the IOVAs are mapped to PFNs. iommufd intends to be general and consumable by any driver that wants to DMA to userspace. From a driver perspective it can largely be dropped in in-place of iommu_attach_device() and provides a uniform full feature set to all consumers. As this is a larger project this series is the first step. This series provides the iommfd "generic interface" which is designed to be suitable for applications like DPDK and VMM flows that are not optimized to specific HW scenarios. It is close to being a drop in replacement for the existing VFIO type 1. This is part two of three for an initial sequence:  - Move IOMMU Group security into the iommu layer    https://lore.kernel.org/linux-iommu/20220218005521.172832-1-baolu.lu@linux.…  * Generic IOMMUFD implementation  - VFIO ability to consume IOMMUFD    An early exploration of this is available here:     https://github.com/luxis1999/iommufd/commits/iommufd-v5.17-rc6 Various parts of the above extended features are in WIP stages currently to define how their IOCTL interface should work. At this point, using the draft VFIO series, unmodified qemu has been tested to operate using iommufd on x86 and ARM systems. Several people have contributed directly to this work: Eric Auger, Kevin Tian, Lu Baolu, Nicolin Chen, Yi L Liu. Many more have participated in the discussions that lead here, and provided ideas.

[PATCH] uadk: parse epoll flag from environment variable
by Zhiqi Song 16 Mar '22

16 Mar '22

From: Wenkai Lin <linwenkai6(a)hisilicon.com> wd_parse_epoll_en is used to parse epoll enable flag from environment variable, it's return value is stored in global variable of each process. When uadk works in synchronize mode, it will check the global variable and decide whether to use wd_ctx_wait. HPRE algorithm(ecc, rsa, dh) is also support epoll wait now.

[PATCH] uadk: parse epoll flag from environment variable
by Zhiqi Song 16 Mar '22

16 Mar '22

From: Wenkai Lin <linwenkai6(a)hisilicon.com> wd_parse_epoll_en is used to parse epoll enable flag from environment variable, it's return value is stored in global variable of each process. When uadk works in synchronize mode, it will check the global variable and decide whether to use wd_ctx_wait. HPRE algorithm(ecc, rsa, dh) is also support epoll wait now.

-------- Forwarded Message -------- Subject: [PATCH v4 00/32] KVM: s390: enable zPCI for interpretive execution Date: Mon, 14 Mar 2022 15:44:19 -0400 From: Matthew Rosato <mjrosato(a)linux.ibm.com> To: linux-s390(a)vger.kernel.org CC: kvm(a)vger.kernel.org, david(a)redhat.com, thuth(a)redhat.com, linux-kernel(a)vger.kernel.org, vneethv(a)linux.ibm.com, agordeev(a)linux.ibm.com, imbrenda(a)linux.ibm.com, will(a)kernel.org, frankja(a)linux.ibm.com, corbet(a)lwn.net, linux-doc(a)vger.kernel.org, pasic(a)linux.ibm.com, jgg(a)nvidia.com, gerald.schaefer(a)linux.ibm.com, borntraeger(a)linux.ibm.com, farman(a)linux.ibm.com, gor(a)linux.ibm.com, schnelle(a)linux.ibm.com, hca(a)linux.ibm.com, alex.williamson(a)redhat.com, freude(a)linux.ibm.com, pmorel(a)linux.ibm.com, cohuck(a)redhat.com, oberpar(a)linux.ibm.com, iommu(a)lists.linux-foundation.org, svens(a)linux.ibm.com, pbonzini(a)redhat.com Note: A few patches in this series are dependent on Baolu's IOMMU domain ops split, which is currently in the next branch of linux-iommu. This series applies on top: https://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu.git Enable interpretive execution of zPCI instructions + adapter interruption forwarding for s390x KVM vfio-pci. This is done by introducing a new IOMMU domain for s390x (KVM-managed), indicating via vfio that this IOMMU domain should be used instead of the default, with subsequent management of the hardware assists being handled via a new KVM ioctl for zPCI management. By allowing intepretation of zPCI instructions and firmware delivery of interrupts to guests, we can significantly reduce the frequency of guest SIE exits for zPCI. We then see additional gains by handling a hot-path instruction that can still intercept to the hypervisor (RPCIT) directly in kvm via the new IOMMU domain, whose map operations update the host DMA table with pinned guest entries over the specified range. From the perspective of guest configuration, you passthrough zPCI devices in the same manner as before, with intepretation support being used by default if available in kernel+qemu. Will reply with a link to the associated QEMU series. Changelog v3->v4: v3: https://lore.kernel.org/kvm/20220204211536.321475-1-mjrosato@linux.ibm.com/ - Significant overhaul of the userspace API. Remove all vfio device feature ioctls. Remove CONFIG_VFIO_PCI_ZDEV, this is once again always built with vfio-pci for s390; IS_ENABLED checks can instead look at CONFIG_VFIO_PCI. Most earlier patches in the series could maintain their reviews, but some needed to be removed due to required code changes. - Instead use a KVM ioctl for zPCI management. The API is very similar to the feature ioctls used in the prior series, with an additional step to create an association between an iommu domain + KVM + zPCI device. - Introduce a new iommu domain ops type for s390-iommu, to be used when KVM manages the IOMMU instead of in response to VFIO mapping ioctls - Add a iommu method for specifying the type of domain to allocate - Add a new type to vfio_iommu_type1 (KVM-owned) to trigger the allocation of the KVM-owned IOMMU domain when zPCI interpretation is requested. In this case, the KVM-owned type is specified on VFIO_SET_IOMMU. - Wire the RPCIT intercepts into the new IOMMU domain via the kernel IOMMU API - Remove a bunch of unnecessary symbol externs, make the associated functions static - Now that we keep a list of zPCI associated with a given KVM, we can do fh lookup on this list vs the list of all zPCI on the host. We only need to do a host-wide fh lookup during the initial device<->KVM association.
