The current implementation delegates the task to calculate the number of processed PCM frames into the context payload processing layer. It looks good as long as frame calculation is done for a single purpose. Nevertheless, another purpose, the computation of extra delay for the runtime of PCM substream, requires frame calculation, too. This commit refactors the current implementation so that the packet stream processing layer is responsible for the calculation of PCM frame, too. The member is moved to stream structure for multiplier between data block count and PCM frame count. Signed-off-by:

A commit baa914cd ("firewire: add kernel API to access CYCLE_TIME register") allow unit drivers to read CYCLE_TIME of 1394 OHCI controller. The value expresses monotonic time with 42.195 Mhz resolution and wrapping around every 128 seconds. The controller uses the time to govern isochronous cycle. This commit extends tracepoints event including the value so that event parser can compute gap between current isochronous cycle and the latest isochronous cycle in which packet is processed (in IR context) or scheduled (in IT context). It loses backward compatibility to former format of the tracepoints event. Signed-off-by:

The history to process isochronous packets is useful when computing gap between current isochronous cycle and the latest isochronous cycle in which packet is processed (in IR context) and scheduled (in IT context). This commit stores the most recent packet descriptors to keep the history. Signed-off-by:

The list of packet descriptor is passed to context payload processing layer so that each driver can copy PCM frames, MIDI messages, and device specific data between packet payload buffer and intermediate buffer for user space application. The list of packet descriptor was replaced by circular linked list in a previous commit. This commit uses circular linked in context payload processing layer as well. Signed-off-by:

Current implementation uses list of packet descriptor as template to schedule isochronous packet. The packet descriptors are operated by position and size, while circular linked list is convenient to enumerate the packet descriptors. This commit utilizes circular linked list for the purpose.

When sequence replay is enabled for media clock recovery, current implementation refers to cache of sequence descriptors in tx packets, then fulfil sequence descriptors for rx packets. The initialization for rx packets is done before starting packet streaming, while it can be postponed till the cache has enough entries for the replay. This commit refactors for the purpose as well as minor code change for renaming of structure member. Signed-off-by:

Add more coverage to our standard test cases: - 8kHz mono and stereo to verify that the most common mono format is clocked correctly. - 44.1kHz stereo to verify that this different clock base is generated accurately. - 48kHz 6 channel to verify that 6 channel is clocked correctly. - 96kHz stereo since that is a common audiophile rate.

In order to help with the comprehensibility of tests it is useful for us to document what the test is attempting to cover. We could just do this through comments in the configuration files but in order to aid people looking at the output of the program in logs let's provide support for an optional 'description' directive which we log prior to running each of the tests.

Since we don't know what the capabilities of an unknown card is any of our standard tests may fail due to not being supported by the system. Set a flag once we've configured the stream, just before we start data, to say that the system accepted our stream configuration. Since there shouldn't be a use case for tests that are specified for the individual system failing for those tests we also add a new test which fails if we are unable to configure the settings specified in the system specific configuration file.

Rather than allowing the system specific tests to replace the default set of tests instead run them in addition to the standard set of tests. In order to avoid name collisions in the reported tests we add an additional test class element to the reported tests. Doing this means we always get a consistent baseline of coverage no matter what card we run on but retain the ability to specify specific coverage for a given system. Reviewed-by:

Obtain all test parameters from the configuration files. The defaults are defined in the pcm-test.conf file. The test count and parameters may be variable per specific hardware. Also, handle alt_formats field now (with the fixes in the format loop). It replaces the original "automatic" logic which is not so universal. The code may be further extended to skip various tests based on the configuration hints, if the exact PCM hardware parameters are not available for the given hardware. Signed-off-by:

Starting from ICL, the default for MIPI GPIO sequences seems to be using native GPIOs i.e. GPIOs available in the GPU. These native GPIOs reuse many pins that quite frankly seem scary to poke based on the VBT sequences. We pretty much have to trust that the board is configured such that the relevant HPD, PP_CONTROL and GPIO bits aren't used for anything else. MIPI sequence v4 also adds a flag to fall back to non-native sequences. v5: - Wrap SHOTPLUG_CTL_DDI modification in spin_lock() in icp_irq_handler() too (Ville) - References instead of Closes issue 6131 because this does not fix everything v4: - Wrap SHOTPLUG_CTL_DDI modification in spin_lock_irq() (Ville) v3: - Fix -Wbitwise-conditional-parentheses (kernel test robot <lkp@intel.com>) v2: - Fix HPD pin output set (impacts GPIOs 0 and 5) - Fix GPIO data output direction set (impacts GPIOs 4 and 9) - Reduce register accesses to single intel_de_rwm() References: https://gitlab.freedesktop.org/drm/intel/-/issues/6131 Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

Guoqing Jiang reports that openSUSE cannot compile the kernel rpm due to "BuildRequires: elfutils-libelf-devel" added by commit 8818039f ("kbuild: add ability to make source rpm buildable using koji"). The relevant package name in openSUSE is libelf-devel. Add it as an alternative package. BTW, if it is impossible to solve the build requirement, the final resort would be: $ make RPMOPTS=--nodeps rpm-pkg This passes --nodeps to the rpmbuild command so it will not verify build dependencies. This is useful to test rpm builds on non-rpm system. On Debian/Ubuntu, for example, you can install rpmbuild by 'apt-get install rpm'. NOTE1: Likewise, it is possible to bypass the build dependency check for debian package builds: $ make DPKG_FLAGS=-d deb-pkg NOTE2: The 'or' operator is supported since RPM 4.13. So, old distros such as CentOS 7 will break. I suggest installing newer rpmbuild in such cases.

commit 3d57e1b7 ("kbuild: refactor the prerequisites of the modpost rule") moved 'vmlinux.o' inside modpost-args, possibly before some of the other options. However, getopt() in musl libc follows POSIX and stops looking for options upon reaching the first non-option argument. As a result, the '-T' option is misinterpreted as a positional argument, and the build fails: make -f ./scripts/Makefile.modpost scripts/mod/modpost -E -o Module.symvers vmlinux.o -T modules.order -T: No such file or directory make[1]: *** [scripts/Makefile.modpost:137: Module.symvers] Error 1 make: *** [Makefile:1960: modpost] Error 2 The fix is to move all options before 'vmlinux.o' in modpost-args.

Dennis Gilmore reports that the BuildID is missing in the arm64 vmlinux since commit 994b7ac1 ("arm64: remove special treatment for the link order of head.o"). The issue is that the type of .notes section, which contains the BuildID, changed from NOTES to PROGBITS. Ard Biesheuvel figured out that whichever object gets linked first gets to decide the type of a section. The PROGBITS type is the result of the compiler emitting .note.GNU-stack as PROGBITS rather than NOTE. While Ard provided a fix for arm64, I want to fix this globally because the same issue is happening on riscv since commit 2348e6bf ("riscv: remove special treatment for the link order of head.o"). This problem will happen in general for other architectures if they start to drop unneeded entries from scripts/head-object-list.txt. Discard .note.GNU-stack in include/asm-generic/vmlinux.lds.h.

The catch-all evict can fail due to object lock contention, since it only goes as far as trylocking the object, due to us already holding the vm->mutex. Doing a full object lock here can deadlock, since the vm->mutex is always our inner lock. Add another execbuf pass which drops the vm->mutex and then tries to grab the object will the full lock, before then retrying the eviction. This should be good enough for now to fix the immediate regression with userspace seeing -ENOSPC from execbuf due to contended object locks during GTT eviction. v2 (Mani) - Also revamp the docs for the different passes.
