From e42839b012eb8179ed2e3571bfcd133fba5df154 Mon Sep 17 00:00:00 2001 From: Mengdong Lin Date: Thu, 24 Mar 2016 10:53:14 +0800 Subject: ASoC: topology: ABI - Define types for vendor tuples Tuples, a pair of token and value, can be used to define vendor specific data, for controls and widgets. This can avoid importing binary data blob from other files. Vendor specific tuple arrays will be embeded in the private data buffer of a control or widget object. To be backward compatible, union is used to define the tuple arrays in the existing private data ABI object 'struct snd_soc_tplg_private'. Vendors need to make sure the token values defined by the topology conf file match those defined by their driver. Now supported tuple types are uuid, string, bool, byte, short and word.

Right now exynos is exposing DPI as a TMDS encoder and VGA connector, which seems rather misleading. This isn't just an internal detail, since xrandr actually exposes "VGA" as the output name. Define some new enums so that vc4's DPI can have a more informative name. I considered other names for the connector as well. For VC4, the Adafruit DPI kippah takes the 28 GPIO pins and routes them to a standard-ish 40-pin FPC connector, but "40-pin FPC" doesn't uniquely identify an ordering of pins (apparently some other orderings exist), doesn't explain things as well for the user (who, if anything, knows their product is a DPI kippah/panel combo), and actually doesn't have to exist (one could connect the 28 GPIOs directly to something else). Simply "DPI" seems like a good compromise name to distinguish from the HDMI, DSI, and TV connectors .

The output is written to the provided buffer, based on the assumption that the values are only needed in userspace. Future support for other types of key derivation would involve a new command, like KEYCTL_ECDH_COMPUTE.

It is also clear that future platform generations (ACPI or not) will continue to revise and extend the DIMM command set as new devices and use cases arrive. It is obviously untenable to continue to proliferate divergence of these command definitions, and to that end a standardization process has begun to provide for a unified specification. However, that leaves a problem about what to do with this first generation where vendors are already shipping divergence. The Linux kernel can support these initial diverged platforms without giving platform-firmware free reign to continue to diverge and compound kernel maintenance overhead. The kernel implementation can encourage standardization in two ways: 1/ Require that any function code that userspace wants to send be explicitly white-listed in the implementation. For ACPI this means function codes marked as supported by acpi_check_dsm() may only be invoked if they appear in the white-list. A function must be publicly documented before it is added to the white-list. 2/ The above restrictions can be trivially bypassed by using the "vendor-specific" payload command. However, since vendor-specific commands are by definition not publicly documented and have the potential to corrupt the kernel's view of the dimm state, we provide a toggle to disable vendor-specific operations. Enabling undefined behavior is a policy decision that can be made by the platform owner and encourages firmware implementations to choose public over private command implementations.

This may happen concurrently with a PCIe hotplug driver if enabled. When all downstream devices are removed and the link state transitions to disabled, the DPC driver clears the DPC status and interrupt bits so the link may retrain for a newly connected device.

This is okay for all archs except PowerPC which can have higher ids, depending on the cpu/core/thread topology. In the worst case (single threaded guest, host with 8 threads per core), it limits the maximum number of vCPUS to KVM_MAX_VCPUS / 8. This patch separates the vCPU numbering from the total number of vCPUs, with the introduction of KVM_MAX_VCPU_ID, as the maximal valid value for vCPU ids plus one. The corresponding KVM_CAP_MAX_VCPU_ID allows userspace to validate vCPU ids before passing them to KVM_CREATE_VCPU. This patch only implements KVM_MAX_VCPU_ID with a specific value for PowerPC. Other archs continue to return KVM_MAX_VCPUS instead.

This is less harsh than doing a controller reset, which temporarilly halts all IO, just to surface a newly attached namespace. This is mainly useful for controllers that implement the namespace management command, but do not support the namespace notify change asynchronous event notification.
