[PATCH] soundwire: cadence_master: always set CMD_ACCEPT
by Bard Liao 19 Apr '21

19 Apr '21

From: Pierre-Louis Bossart <pierre-louis.bossart(a)linux.intel.com> The Cadence IP can be configured in two different ways to deal with CMD_IGNORED replies to broadcast commands. The CMD_ACCEPT bitfield controls whether the command is discarded or if the IP proceeds with the change (typically a bank switch or clock stop command). The existing code seems to be inconsistent: a) For some historical reason, we set this CMD_ACCEPT bitfield during the initialization, but we don't during a resume from a clock-stoppped state. b) In addition, the loop used in the clock-stop sequence is quite racy, it's possible that a device has lost sync but it's still tagged as ATTACHED. c) If somehow a Device loses sync and is unable to ack a broadcast command, we do not have an error handling mechanism anyways. The IP should go ahead and let the Device regain sync at a later time. Make sure the CMD_ACCEPT bit is always set.

[PATCH v3] soundwire: intel: move to auxiliary bus
by Bard Liao 19 Apr '21

19 Apr '21

From: Pierre-Louis Bossart <pierre-louis.bossart(a)linux.intel.com> Now that the auxiliary_bus exists, there's no reason to use platform devices as children of a PCI device any longer. This patch refactors the code by extending a basic auxiliary device with Intel link-specific structures that need to be passed between controller and link levels. This refactoring is much cleaner with no need for cross-pointers between device and link structures. Note that the auxiliary bus API has separate init and add steps, which requires more attention in the error unwinding paths. The main loop needs to deal with kfree() and auxiliary_device_uninit() for the current iteration before jumping to the common label which releases everything allocated in prior iterations.

[PATCH v3] ALSA: control: Add memory consumption limit to user controls
by Takashi Sakamoto 18 Apr '21

18 Apr '21

ALSA control interface allows users to add arbitrary control elements (called "user controls" or "user elements"), and its resource usage is limited just by the max number of control sets (currently 32). This limit, however, is quite loose: each allocation of control set may have 1028 elements, and each element may have up to 512 bytes (ILP32) or 1024 bytes (LP64) of value data. Moreover, each control set may contain the enum strings and TLV data, which can be up to 64kB and 128kB, respectively. Totally, the whole memory consumption may go over 38MB -- it's quite large, and we'd rather like to reduce the size. OTOH, there have been other requests even to increase the max number of user elements; e.g. ALSA firewire stack require the more user controls, hence we want to raise the bar, too. For satisfying both requirements, this patch changes the management of user controls: instead of setting the upper limit of the number of user controls, we check the actual memory allocation size and set the upper limit of the total allocation in bytes. As long as the memory consumption stays below the limit, more user controls are allowed than the current limit 32. At the same time, we set the lower limit (8MB) as default than the current theoretical limit, in order to lower the risk of DoS. As a compromise for lowering the default limit, now the actual memory limit is defined as a module option, 'max_user_ctl_alloc_size', so that user can increase/decrease the limit if really needed, too.

This reverts commit e61c589587c772c5f672b22683c3e0b38be20702. The binding document has lots of schema errors and there's been no effort to fix them, so let's remove it.
