Linux kernel source tree
924ebaefce
- Add support for FF-A 1.2 as the secure memory conduit for pKVM, allowing more registers to be used as part of the message payload. - Change the way pKVM allocates its VM handles, making sure that the privileged hypervisor is never tricked into using uninitialised data. - Speed up MMIO range registration by avoiding unnecessary RCU synchronisation, which results in VMs starting much quicker. - Add the dump of the instruction stream when panic-ing in the EL2 payload, just like the rest of the kernel has always done. This will hopefully help debugging non-VHE setups. - Add 52bit PA support to the stage-1 page-table walker, and make use of it to populate the fault level reported to the guest on failing to translate a stage-1 walk. - Add NV support to the GICv3-on-GICv5 emulation code, ensuring feature parity for guests, irrespective of the host platform. - Fix some really ugly architecture problems when dealing with debug in a nested VM. This has some bad performance impacts, but is at least correct. - Add enough infrastructure to be able to disable EL2 features and give effective values to the EL2 control registers. This then allows a bunch of features to be turned off, which helps cross-host migration. - Large rework of the selftest infrastructure to allow most tests to transparently run at EL2. This is the first step towards enabling NV testing. - Various fixes and improvements all over the map, including one BE fix, just in time for the removal of the feature. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEn9UcU+C1Yxj9lZw9I9DQutE9ekMFAmjVhSsACgkQI9DQutE9 ekOSIg//YdbA/zo17GrLnJnlGdUnS0e3/357n3e5Lypx1UFRDTmNacpVPw4VG/jt eVpQn7AgYwyvKfCq46eD+hBBqNv1XTn4DeXttv7CmVqhCRythsEvDkTBWSt7oYUZ xfYXCMKNhqUElH4AbYYx3y7nb2E9/KVGr+NBn6Vf5c14OZ3MGVc/fyp4jM1ih5dR kcV2onAYohlIGvFEyZMBtJ+jkYkqfIbfxfqCL0RAET0aEBFcmM1aXybWZj47hlLM f2j+E6cFQ0ZzUt+3pFhT75wo43lHGtIFDjVd60uishyU+NXTVvqRmXDTRU4k546W 18HHX1yijbzuXIatVhVRo2hIq3jKU37T9wtj46BejbDHRdAPENEyN/Qopm7rNS+X mCwOT7He6KR+H4rU6nFaTcsS7bNRCvIbZP9i9zb6NElbvXu5QnM8BUQsYFCDUa/n xtbtQlckbo/7zeoUsBDrGj2XmCf0d45FTHb7fdWOYEmMSmJhXYpUKdM4JcLyhKoQ DD0ox2S+pt2lwNw3XOSABdES0KJxCvDASAMIgn2h2sGpY8FxsBcVW/BufXopdafG UeInxWaILp2iCDM4tH2GLjKqlvMAOwcA+mAEZToXypxlJAnYA6J1pXCF8WEaM6+D BGrLli8Zd8JRs87byq6K7tp8oLNzZdliJp73j5jfOHTJA4MnvFI= =iAL3 -----END PGP SIGNATURE----- Merge tag 'kvmarm-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD KVM/arm64 updates for 6.18 - Add support for FF-A 1.2 as the secure memory conduit for pKVM, allowing more registers to be used as part of the message payload. - Change the way pKVM allocates its VM handles, making sure that the privileged hypervisor is never tricked into using uninitialised data. - Speed up MMIO range registration by avoiding unnecessary RCU synchronisation, which results in VMs starting much quicker. - Add the dump of the instruction stream when panic-ing in the EL2 payload, just like the rest of the kernel has always done.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
