2021-08-24drm/amdgpu: Fix build with missing pm_suspend_target_state module exportBorislav Petkov
Building a randconfig here triggered: ERROR: modpost: "pm_suspend_target_state" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined! because the module export of that symbol happens in kernel/power/suspend.c which is enabled with CONFIG_SUSPEND. The ifdef guards in amdgpu_acpi_is_s0ix_supported(), however, test for CONFIG_PM_SLEEP which is defined like this: config PM_SLEEP def_bool y depends on SUSPEND || HIBERNATE_CALLBACKS and that randconfig has: # CONFIG_SUSPEND is not set CONFIG_HIBERNATE_CALLBACKS=y leading to the module export missing. Change the ifdeffery to depend directly on CONFIG_SUSPEND.

2021-08-24drm/amdgpu/OLAND: clip the ref divider max valueShashank Sharma
This patch limits the ref_div_max value to 100, during the calculation of PLL feedback reference divider. With current value (128), the produced fb_ref_div value generates unstable output at particular frequencies. Radeon driver limits this value at 100. On Oland, when we try to setup mode 2048x1280@60 (a bit weird, I know), it demands a clock of 221270 Khz. It's been observed that the PLL calculations using values 128 and 100 are vastly different, and look like this: +------------------------------------------+ |Parameter |AMDGPU |Radeon | | | | | +-------------+----------------------------+ |Clock feedback | | |divider max | 128 | 100 | |cap value | | | | | | | | | | | +------------------------------------------+ |ref_div_max | | | | | 42 | 20 | | | | | | | | | +------------------------------------------+ |ref_div | 42 | 20 | | | | | +------------------------------------------+ |fb_div | 10326 | 8195 | +------------------------------------------+ |fb_div | 1024 | 163 | +------------------------------------------+ |fb_dev_p | 4 | 9 | |frac fb_de^_p| | | +----------------------------+-------------+ With ref_div_max value clipped at 100, AMDGPU driver can also drive videmode 2048x1280@60 (221Mhz) and produce proper output without any blanking and distortion on the screen. PS: This value was changed from 128 to 100 in Radeon driver also, here: https://github.com/freedesktop/drm-tip/commit/4b21ce1b4b5d262e7d4656b8ececc891fc3cb806 V1: Got acks from: Acked-by: Alex Deucher <alexander.deucher@amd.com> Acked-by: Christian König <christian.koenig@amd.com> V2: - Restricting the changes only for OLAND, just to avoid any regression for other cards. - Changed unsigned -> unsigned int to make checkpatch quiet.

2021-08-24libnvdimm/labels: Add claim class helpersDan Williams
In preparation for LIBNVDIMM to manage labels on CXL devices deploy helpers that abstract the label type from the implementation. The CXL label format is mostly similar to the EFI label format with concepts / fields added, like dynamic region creation and label type guids, and other concepts removed like BLK-mode and interleave-set-cookie ids. CXL labels do have the concept of a claim class represented by an "abstraction" identifier. It turns out both label implementations use the same ids, but EFI encodes them as GUIDs and CXL labels encode them as UUIDs. For now abstract out the claim class such that the UUID vs GUID distinction can later be hidden in the helper.

2021-08-24igc: Add support for PTP getcrosststamp()Vinicius Costa Gomes
i225 supports PCIe Precision Time Measurement (PTM), allowing us to support the PTP_SYS_OFFSET_PRECISE ioctl() in the driver via the getcrosststamp() function. The easiest way to expose the PTM registers would be to configure the PTM dialogs to run periodically, but the PTP_SYS_OFFSET_PRECISE ioctl() semantics are more aligned to using a kind of "one-shot" way of retrieving the PTM timestamps. But this causes a bit more code to be written: the trigger registers for the PTM dialogs are not cleared automatically. i225 can be configured to send "fake" packets with the PTM information, adding support for handling these types of packets is left for the future. PTM improves the accuracy of time synchronization, for example, using phc2sys, while a simple application is sending packets as fast as possible.

For two runs of 16466 entries: without PTM: avg -0.04 stdev 10.57 max 39 min -42 with PTM: avg 0.01 stdev 4.20 max 19 min -16 One possible explanation is that when PTM is not enabled, and there's a lot of traffic in the PCIe fabric, some register reads will take more time than the others because of congestion on the PCIe fabric. When PTM is enabled, even if the PTM dialogs take more time to complete under heavy traffic, the time measurements do not depend on the time to read the registers. This was implemented following the i225 EAS version 0.993.

Enables PCIe PTM (Precision Time Measurement) support in the igc driver. Notifies the PCI devices that PCIe PTM should be enabled. PCIe PTM is similar protocol to PTP (Precision Time Protocol) running in the PCIe fabric, it allows devices to report time measurements from their internal clocks and the correlation with the PCIe root clock. The i225 NIC exposes some registers that expose those time measurements, those registers will be used, in later patches, to implement the PTP_SYS_OFFSET_PRECISE ioctl().

2021-08-24s390/vfio-ap: replace open coded locks for VFIO_GROUP_NOTIFY_SET_KVM ↵Tony Krowiak
notification It was pointed out during an unrelated patch review that locks should not be open coded - i.e., writing the algorithm of a standard lock in a function instead of using a lock from the standard library. The setting and testing of a busy flag and sleeping on a wait_event is the same thing a lock does. The open coded locks are invisible to lockdep, so potential locking problems are not detected. This patch removes the open coded locks used during VFIO_GROUP_NOTIFY_SET_KVM notification. The busy flag and wait queue were introduced to resolve a possible circular locking dependency reported by lockdep when starting a secure execution guest configured with AP adapters and domains. Reversing the order in which the kvm->lock mutex and matrix_dev->lock mutex are locked resolves the issue reported by lockdep, thus enabling the removal of the open coded locks.

The function pointer to the interception handler for the PQAP instruction can get changed during the interception process.

The semaphore must be locked for write access by the vfio_ap device driver when notified that the KVM pointer has been set or cleared. It must be locked for read access by the interception framework when the PQAP instruction is intercepted.
