2022-12-16drm/imx: move IPUv3 driver into separate subdirectoryLucas Stach
The IPUv3 and DCSS driver are two totally separate DRM drivers. Having one of them live in the drivers/gpu/drm/imx toplevel directory and the other one in the dcss/ subdirectory is confusing. Move the IPUv3 driver into its own subdirectory to make the separation more clear.

2022-12-16drm/imx: ipuv3-plane: Fix overlay plane widthPhilipp Zabel
ipu_src_rect_width() was introduced to support odd screen resolutions such as 1366x768 by internally rounding up primary plane width to a multiple of 8 and compensating with reduced horizontal blanking. This also caused overlay plane width to be rounded up, which was not intended. Fix overlay plane width by limiting the rounding up to the primary plane. drm_rect_width(&new_state->src) >> 16 is the same value as drm_rect_width(dst) because there is no plane scaling support.

2022-12-16of: fdt: Honor CONFIG_CMDLINE* even without /chosen nodeAlexander Sverdlin
I do not read a strict requirement on /chosen node in either ePAPR or in Documentation/devicetree. Help text for CONFIG_CMDLINE and CONFIG_CMDLINE_EXTEND doesn't make their behavior explicitly dependent on the presence of /chosen or the presense of /chosen/bootargs. However the early check for /chosen and bailing out in early_init_dt_scan_chosen() skips CONFIG_CMDLINE handling which is not really related to /chosen node or the particular method of passing cmdline from bootloader. This leads to counterintuitive combinations (assuming CONFIG_CMDLINE_EXTEND=y): a) bootargs="foo", CONFIG_CMDLINE="bar" => cmdline=="foo bar" b) /chosen missing, CONFIG_CMDLINE="bar" => cmdline=="" c) bootargs="", CONFIG_CMDLINE="bar" => cmdline==" bar" Move CONFIG_CMDLINE handling outside of early_init_dt_scan_chosen() so that cases b and c above result in the same cmdline.

2022-12-16drm/display/dp_mst: Fix payload addition on a disconnected sinkImre Deak
If an MST stream is enabled on a disconnected sink, the payload for the stream is not created and the MST manager's payload count/next start VC slot is not updated. Since the payload's start VC slot may still contain a valid value (!= -1) the subsequent disabling of such a stream could cause an incorrect decrease of the payload count/next start VC slot in drm_dp_remove_payload() and hence later payload additions will fail. Fix the above by marking the payload as invalid in the above case, so that it's skipped during payload removal. While at it add a debug print for this case.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core updates from Greg KH: "Here is the set of driver core and kernfs changes for 6.2-rc1. The "big" change in here is the addition of a new macro, container_of_const() that will preserve the "const-ness" of a pointer passed into it. The "problem" of the current container_of() macro is that if you pass in a "const *", out of it can comes a non-const pointer unless you specifically ask for it. For many usages, we want to preserve the "const" attribute by using the same call. For a specific example, this series changes the kobj_to_dev() macro to use it, allowing it to be used no matter what the const value is. This prevents every subsystem from having to declare 2 different individual macros (i.e. kobj_const_to_dev() and kobj_to_dev()) and having the compiler enforce the const value at build time, which having 2 macros would not do either. The driver for all of this have been discussions with the Rust kernel developers as to how to properly mark driver core, and kobject, objects as being "non-mutable". The changes to the kobject and driver core in this pull request are the result of that, as there are lots of paths where kobjects and device pointers are not modified at all, so marking them as "const" allows the compiler to enforce this. So, a nice side affect of the Rust development effort has been already to clean up the driver core code to be more obvious about object rules. All of this has been bike-shedded in quite a lot of detail on lkml with different names and implementations resulting in the tiny version we have in here, much better than my original proposal. Lots of subsystem maintainers have acked the changes as well. Other than this change, included in here are smaller stuff like: - kernfs fixes and updates to handle lock contention better - vmlinux.lds.h fixes and updates - sysfs and debugfs documentation updates - device property updates All of these have been in the linux-next tree for quite a while with no problems" * tag 'driver-core-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (58 commits) device property: Fix documentation for fwnode_get_next_parent() firmware_loader: fix up to_fw_sysfs() to preserve const usb.h: take advantage of container_of_const() device.h: move kobj_to_dev() to use container_of_const() container_of: add container_of_const() that preserves const-ness of the pointer driver core: fix up missed drivers/s390/char/hmcdrv_dev.c class.devnode() conversion. driver core: fix up missed scsi/cxlflash class.devnode() conversion. driver core: fix up some missing class.devnode() conversions. driver core: make struct class.devnode() take a const * driver core: make struct class.dev_uevent() take a const * cacheinfo: Remove of_node_put() for fw_token device property: Add a blank line in Kconfig of tests device property: Rename goto label to be more precise device property: Move PROPERTY_ENTRY_BOOL() a bit down device property: Get rid of __PROPERTY_ENTRY_ARRAY_EL*SIZE*() kernfs: fix all kernel-doc warnings and multiple typos driver core: pass a const * into of_device_uevent() kobject: kset_uevent_ops: make name() callback take a const * kobject: kset_uevent_ops: make filter() callback take a const * kobject: make kobject_namespace take a const * ...

2022-12-15rtc: isl12026: drop obsolete dependency on COMPILE_TESTJean Delvare
Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues.

2022-12-15igc: Set Qbv start_time and end_time to end_time if not being configured in GCLTan Tee Min
The default setting of end_time minus start_time is whole 1 second. Thus, if it's not being configured in any GCL entry then it will be staying at original 1 second. This patch is changing the start_time and end_time to be end_time as if setting zero will be having weird HW behavior where the gate will not be fully closed.

2022-12-15igc: recalculate Qbv end_time by considering cycle timeTan Tee Min
Qbv users can specify a cycle time that is not equal to the total GCL intervals. Hence, recalculation is necessary here to exclude the time interval that exceeds the cycle time. As those GCL which exceeds the cycle time will be truncated. According to IEEE Std. 802.1Q-2018 section 8.6.9.2, once the end of the list is reached, it will switch to the END_OF_CYCLE state and leave the gates in the same state until the next cycle is started.

2022-12-15igc: Enhance Qbv scheduling by using first flag bitVinicius Costa Gomes
The I225 hardware has a limitation that packets can only be scheduled in the [0, cycle-time] interval. So, scheduling a packet to the start of the next cycle doesn't usually work. To overcome this, we use the Transmit Descriptor first flag to indicates that a packet should be the first packet (from a queue) in a cycle according to the section 7.5.2.9.3.4 The First Packet on Each QBV Cycle in Intel Discrete I225/6 User Manual. But this only works if there was any packet from that queue during the current cycle, to avoid this issue, we issue an empty packet if that's not the case. Also require one more descriptor to be available, to take into account the empty packet that might be issued. Test Setup: Talker: Use l2_tai to generate the launchtime into packet load. Listener: Use timedump.c to compute the delta between packet arrival and LaunchTime packet payload.

Pull kvm updates from Paolo Bonzini: "ARM64: - Enable the per-vcpu dirty-ring tracking mechanism, together with an option to keep the good old dirty log around for pages that are dirtied by something other than a vcpu. - Switch to the relaxed parallel fault handling, using RCU to delay page table reclaim and giving better performance under load. - Relax the MTE ABI, allowing a VMM to use the MAP_SHARED mapping option, which multi-process VMMs such as crosvm rely on (see merge commit 382b5b87a97d: "Fix a number of issues with MTE, such as races on the tags being initialised vs the PG_mte_tagged flag as well as the lack of support for VM_SHARED when KVM is involved. Patches from Catalin Marinas and Peter Collingbourne"). - Merge the pKVM shadow vcpu state tracking that allows the hypervisor to have its own view of a vcpu, keeping that state private. - Add support for the PMUv3p5 architecture revision, bringing support for 64bit counters on systems that support it, and fix the no-quite-compliant CHAIN-ed counter support for the machines that actually exist out there. - Fix a handful of minor issues around 52bit VA/PA support (64kB pages only) as a prefix of the oncoming support for 4kB and 16kB pages. - Pick a small set of documentation and spelling fixes, because no good merge window would be complete without those. s390: - Second batch of the lazy destroy patches - First batch of KVM changes for kernel virtual != physical address support - Removal of a unused function x86: - Allow compiling out SMM support - Cleanup and documentation of SMM state save area format - Preserve interrupt shadow in SMM state save area - Respond to generic signals during slow page faults - Fixes and optimizations for the non-executable huge page errata fix. - Reprogram all performance counters on PMU filter change - Cleanups to Hyper-V emulation and tests - Process Hyper-V TLB flushes from a nested guest (i.e. from a L2 guest running on top of a L1 Hyper-V hypervisor) - Advertise several new Intel features - x86 Xen-for-KVM: - Allow the Xen runstate information to cross a page boundary - Allow XEN_RUNSTATE_UPDATE flag behaviour to be configured - Add support for 32-bit guests in SCHEDOP_poll - Notable x86 fixes and cleanups: - One-off fixes for various emulation flows (SGX, VMXON, NRIPS=0). - Reinstate IBPB on emulated VM-Exit that was incorrectly dropped a few years back when eliminating unnecessary barriers when switching between vmcs01 and vmcs02. - Clean up vmread_error_trampoline() to make it more obvious that params must be passed on the stack, even for x86-64. - Let userspace set all supported bits in MSR_IA32_FEAT_CTL irrespective of the current guest CPUID. - Fudge around a race with TSC refinement that results in KVM incorrectly thinking a guest needs TSC scaling when running on a CPU with a constant TSC, but no hardware-enumerated TSC frequency. - Advertise (on AMD) that the SMM_CTL MSR is not supported - Remove unnecessary exports Generic: - Support for responding to signals during page faults; introduces new FOLL_INTERRUPTIBLE flag that was reviewed by mm folks Selftests: - Fix an inverted check in the access tracking perf test, and restore support for asserting that there aren't too many idle pages when running on bare metal. - Fix build errors that occur in certain setups (unsure exactly what is unique about the problematic setup) due to glibc overriding static_assert() to a variant that requires a custom message. - Introduce actual atomics for clear/set_bit() in selftests - Add support for pinning vCPUs in dirty_log_perf_test. - Rename the so called "perf_util" framework to "memstress". - Add a lightweight psuedo RNG for guest use, and use it to randomize the access pattern and write vs. read percentage in the memstress tests. - Add a common ucall implementation; code dedup and pre-work for running SEV (and beyond) guests in selftests. - Provide a common constructor and arch hook, which will eventually be used by x86 to automatically select the right hypercall (AMD vs. Intel). - A bunch of added/enabled/fixed selftests for ARM64, covering memslots, breakpoints, stage-2 faults and access tracking. - x86-specific selftest changes: - Clean up x86's page table management. - Clean up and enhance the "smaller maxphyaddr" test, and add a related test to cover generic emulation failure. - Clean up the nEPT support checks. - Add X86_PROPERTY_* framework to retrieve multi-bit CPUID values. - Fix an ordering issue in the AMX test introduced by recent conversions to use kvm_cpu_has(), and harden the code to guard against similar bugs in the future. Anything that tiggers caching of KVM's supported CPUID, kvm_cpu_has() in this case, effectively hides opt-in XSAVE features if the caching occurs before the test opts in via prctl().
