2022-05-10ASoC: SOF: ipc: introduce cont_update_posn in sof_ipc_stream_params structYC Hung2-2/+3
The host stream position is updated when no_stream_position is set as 0. However current implementation updates host stream position only when report data is larger than or equal to host period size which is decided by the period size of host side. It maybe cause host stream position update not in time. Therefore this patch introduces another field "cont_update_posn", a boolean value aimed to update host stream position continuously and based on period size of pipeline. It can get better precise when need to update host stream position from firmware.

Change the order of members in struct cs_dsp_coeff_ctl to avoid the compiler having to insert alignment padding bytes. On a x86_64 build this saves 16 bytes per control. - Pointers are collected to the top of the struct (with the exception of priv, as noted below), so that they are inherently aligned. - The set and enable bitflags are placed together so they can be merged. - priv is placed at the end of the struct - it is for use by the client so it is helpful to make it stand out, and since the compiler will always pad the struct size to an alignment multiple putting a pointer last won't introduce any more padding. - struct cs_dsp_alg_region is placed at the end, right before priv, for the same reasoning as priv.

2022-04-20ASoC: SOF: add INTEL_IPC4 plumbingMark Brown1-4/+19
Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>: The INTEL_IPC4 protocol and firmware architecture will rely on different sets of firmware binary and topology files. Some platforms will only support INTEL_IPC4, some will support both INTEL_IPC4 and SOF_IPC for development, and some will stay with the existing SOF_IPC. This patchset adds new IPC definitions, and search paths for firmware and topology files, along with means to override the default IPC type and search paths for development. The firmware binary names are aligned with those used by the Intel AVS driver to avoid duplicate firmware installs, but the topology will have to differ due to driver architecture differences.
2022-04-20ASoC: Intel: avs: Topology and path managementMark Brown1-0/+126
Merge series from Cezary Rojewski <cezary.rojewski@intel.com>: A continuation of avs-driver initial series [1]. This chapter covers path management and topology parsing part which was ealier path of the main series. The two patches that represented these two subjects in the initial series, have been split into many to allow for easier review and discussion. AVS topology is split into two major parts: dictionaries - found within ASoC topology manifest - and path templates. Dictionaries job is to reduce the total amount of memory occupied by topology elements. Rather than having every pipeline and module carry its own information, each refers to specific entry in specific dictionary by provided (from topology file) indexes. In consequence, most struct avs_tplg_xxx are made out of pointers. Path templates are similar to path descriptions found in skylake-driver and they describe how given path shall look like in runtime - number of modules and pipelines that shape it and how they are laid out. A single path template is tied either to FE or BE and thus at most to a single, user-visible endpoint when speaking of FE. Path is a software representation of its ADSP firmware equivalent. It's a logical container for pipelines which are themselves containers - this time for modules i.e. processing units. Depending on the number of audio formats supported, each path template may carry one or more descriptions of given path. During runtime, when audio format is known, description matching said format is selected and used when instantiating path on ADSP firmware side through IPCs.

Commit 3aa1e96a2b95 ("ASoC: soc-pcm: fix BE handling of PAUSE_RELEASE") did not modify the existing logic and kept the same logic for the following transition play FE1 -> BE state is START pause FE1 -> BE state is PAUSED play FE2 -> BE state is START stop FE2 -> BE state is STOP <<< !! release FE1 -> BE state is START stop FE1 -> BE state is STOP At the time it was identified by reviewers that a better solution might consist in play FE1 -> BE state is START pause FE1 -> BE state is PAUSED play FE2 -> BE state is START stop FE2 -> BE state is PAUSE <<< !! release FE1 -> BE state is START stop FE1 -> BE state is STOP This patch suggest a transition to PAUSE when all the 'active' streams are paused. This would allow for a more consistent resource management for platforms where PAUSE and STOP are handled differently. To track the special case of an FE going from PAUSE_PUSH to STOP, we add a state variable for each FE context. This 'fe_pause' boolean is set on PAUSE_PUSH and cleared on either PAUSE_RELEASE and STOP triggers.

Add a helper function snd_soc_tdm_params_to_bclk() to calculate the bclk from params info and the tdm sots configuration. When using a TDM frame of N slots of width W bits: bclk = sample_rate * N * W As a convenience to simplify calling code, if the slot count or slot width are 0 a value will be obtained from the params. This allows calling code to use this one function to handle cases of TDM where only one parameter is fixed, or I2S where the slot width is fixed (for example to set a 32-bit slot for 24-bit samples). Also as a convenience the slot count can optionally be rounded up to a multiple. This is mainly useful for I2S systems, since I2S has two phases of LRCLK the number of slots is always a multiple of 2.

2022-04-02tracing: mark user_events as BROKENSteven Rostedt (Google)1-0/+0
After being merged, user_events become more visible to a wider audience that have concerns with the current API. It is too late to fix this for this release, but instead of a full revert, just mark it as BROKEN (which prevents it from being selected in make config). Then we can work finding a better API. If that fails, then it will need to be completely reverted. To not have the code silently bitrot, still allow building it with COMPILE_TEST. And to prevent the uapi header from being installed, then later changed, and then have an old distro user space see the old version, move the header file out of the uapi directory. Surround the include with CONFIG_COMPILE_TEST to the current location, but when the BROKEN tag is taken off, it will use the uapi directory, and fail to compile. This is a good way to remind us to move the header back.

While user_events API is under development and has been marked for broken to not let the API become fixed, move the header file out of the uapi directory. This is to prevent it from being installed, then later changed, and then have an old distro user space update with a new kernel, where applications see the user_events being available, but the old header is in place, and then they get compiled incorrectly. Also, surround the include with CONFIG_COMPILE_TEST to the current location, but when the BROKEN tag is taken off, it will use the uapi directory, and fail to compile.

2022-04-02ftrace: Make ftrace_graph_is_dead() a static branchChristophe Leroy1-1/+15
ftrace_graph_is_dead() is used on hot paths, it just reads a variable in memory and is not worth suffering function call constraints. For instance, at entry of prepare_ftrace_return(), inlining it avoids saving prepare_ftrace_return() parameters to stack and restoring them after calling ftrace_graph_is_dead(). While at it using a static branch is even more performant and is rather well adapted considering that the returned value will almost never change. Inline ftrace_graph_is_dead() and replace 'kill_ftrace_graph' bool by a static branch. The performance improvement is noticeable.

2022-04-02tracing: Rename the staging files for trace_eventsSteven Rostedt (Google)9-14/+14
When looking for implementation of different phases of the creation of the TRACE_EVENT() macro, it is pretty useless when all helper macro redefinitions are in files labeled "stageX_defines.h". Rename them to state which phase the files are for. For instance, when looking for the defines that are used to create the event fields, seeing "stage4_event_fields.h" gives the developer a good idea that the defines are in that file.

2022-04-02KVM: Remove dirty handling from gfn_to_pfn_cache completelyDavid Woodhouse2-10/+5
It isn't OK to cache the dirty status of a page in internal structures for an indefinite period of time. Any time a vCPU exits the run loop to userspace might be its last; the VMM might do its final check of the dirty log, flush the last remaining dirty pages to the destination and complete a live migration. If we have internal 'dirty' state which doesn't get flushed until the vCPU is finally destroyed on the source after migration is complete, then we have lost data because that will escape the final copy. This problem already exists with the use of kvm_vcpu_unmap() to mark pages dirty in e.g. VMX nesting. Note that the actual Linux MM already considers the page to be dirty since we have a writeable mapping of it. This is just about the KVM dirty logging. For the nesting-style use cases (KVM_GUEST_USES_PFN) we will need to track which gfn_to_pfn_caches have been used and explicitly mark the corresponding pages dirty before returning to userspace. But we would have needed external tracking of that anyway, rather than walking the full list of GPCs to find those belonging to this vCPU which are dirty. So let's rely *solely* on that external tracking, and keep it simple rather than laying a tempting trap for callers to fall into.

Replace the guest_uses_pa and kernel_map booleans in the PFN cache code with a unified enum/bitmask. Using explicit names makes it easier to review and audit call sites. Opportunistically add a WARN to prevent passing garbage; instantating a cache without declaring its usage is either buggy or pointless.

2022-04-02KVM: Don't actually set a request when evicting vCPUs for GFN cache invdSean Christopherson1-7/+31
Don't actually set a request bit in vcpu->requests when making a request purely to force a vCPU to exit the guest. Logging a request but not actually consuming it would cause the vCPU to get stuck in an infinite loop during KVM_RUN because KVM would see the pending request and bail from VM-Enter to service the request. Note, it's currently impossible for KVM to set KVM_REQ_GPC_INVALIDATE as nothing in KVM is wired up to set guest_uses_pa=true. But, it'd be all too easy for arch code to introduce use of kvm_gfn_to_pfn_cache_init() without implementing handling of the request, especially since getting test coverage of MMU notifier interaction with specific KVM features usually requires a directed test. Opportunistically rename gfn_to_pfn_cache_invalidate_start()'s wake_vcpus to evict_vcpus. The purpose of the request is to get vCPUs out of guest mode, it's supposed to _avoid_ waking vCPUs that are blocking. Opportunistically rename KVM_REQ_GPC_INVALIDATE to be more specific as to what it wants to accomplish, and to genericize the name so that it can used for similar but unrelated scenarios, should they arise in the future. Add a comment and documentation to explain why the "no action" request exists. Add compile-time assertions to help detect improper usage. Use the inner assertless helper in the one s390 path that makes requests without a hardcoded request.
