2021-04-23mmc: mmc_spi: Set up polling even if voltage-ranges is not presentAndy Shevchenko1-3/+3
When voltage-ranges property is not present the driver assumes that it is 3.3v (3.2v..3.4v). But at the same time it disallows polling. Fix that by dropping the comparison to 0 when no property is provided. While at it, mark voltage-ranges property optional as it was initially.

2021-04-21KVM: x86: Support KVM VMs sharing SEV contextNathan Tempelman1-1/+17
Add a capability for userspace to mirror SEV encryption context from one vm to another. On our side, this is intended to support a Migration Helper vCPU, but it can also be used generically to support other in-guest workloads scheduled by the host. The intention is for the primary guest and the mirror to have nearly identical memslots. The primary benefits of this are that: 1) The VMs do not share KVM contexts (think APIC/MSRs/etc), so they can't accidentally clobber each other. 2) The VMs can have different memory-views, which is necessary for post-copy migration (the migration vCPUs on the target need to read and write to pages, when the primary guest would VMEXIT). This does not change the threat model for AMD SEV. Any memory involved is still owned by the primary guest and its initial state is still attested to through the normal SEV_LAUNCH_* flows. If userspace wanted to circumvent SEV, they could achieve the same effect by simply attaching a vCPU to the primary VM. This patch deliberately leaves userspace in charge of the memslots for the mirror, as it already has the power to mess with them in the primary guest. This patch does not support SEV-ES (much less SNP), as it does not handle handing off attested VMSAs to the mirror. For additional context, we need a Migration Helper because SEV PSP migration is far too slow for our live migration on its own. Using an in-guest migrator lets us speed this up significantly.

2021-04-20spi: brcm,spi-bcm-qspi: convert to the json-schemaRafał Miłecki2-245/+198
This helps validating DTS files. Changes that require mentioning: 1. reg-names "mspi_regs" and "bspi_regs" were renamed to "mspi" and "bspi" as that is what's used in DTS files and in Linux driver 2. interrupt-names Names were reordered. "mspi_done" has to go first as it's always required. 3. spi-rx-bus-width Property description was dropped as it's part of the spi-controller.yaml 4. Examples: * drop partitions as they are well documented elsewhere * regs and interrupts were formatted and reordered to match yaml * <0x1c> was replaced with <&gic> * "m25p80" node name became "flash" * dropped invalid "m25p,fast-read" property * dropped undocumented and Linux-unused "clock-names" This rewritten binding validates cleanly using the "dt_binding_check". Some Linux stored DTS files will require reordering regs and interrupts to make dtbs_check happy.

2021-04-20hwmon: Remove amd_energy driverGuenter Roeck2-120/+0
Commit 60268b0e8258 ("hwmon: (amd_energy) modify the visibility of the counters") restricted visibility of AMD energy counters to work around a side-channel attack using energy data to determine which instructions are executed. The attack is described in 'PLATYPUS: Software-based Power Side-Channel Attacks on x86'. It relies on quick and accurate energy readings. This change made the counters provided by the amd_energy driver effectively unusable for non-provileged users. However, unprivileged read access is the whole point of hardware monitoring attributes. An attempt to remedy the situation by limiting and randomizing access to chip registers was rejected by AMD. Since the driver is for all practical purposes unusable, remove it.

2021-04-20hwmon: Clarify scope of attribute accessGuenter Roeck1-0/+8
Hardware monitoring sysfs attributes are used and displayed by unrestricted userspace applications. Standard attributes therefore have to be world readable, since otherwise those userspace applications would either have to run as super-user or display an error. None of those makes sense. Clarify the expected scope of attribute access in the ABI document. Cc: Naveen Krishna Chatradhi <nchatrad@amd.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
