<content type='text'>
commit 5095d5418193 ("drm/amd: Evict resources during PM ops prepare()
callback") intentionally moved the eviction of resources to earlier in
the suspend process, but this introduced a subtle change that it occurs
before adev-&gt;in_s0ix or adev-&gt;in_s3 are set. This meant that APUs
actually started to evict resources at suspend time as well.

Explicitly set s0ix or s3 in the prepare() stage, and unset them if the
prepare() stage failed.

v2: squash in warning fix from Stephen Rothwell

If a user has disabled GFXOFF this may cause problems for the suspend
sequence.  Ensure that it is enabled in amdgpu_acpi_is_s0ix_active().

The system won't reach the deepest state but it also won't hang.

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Use acpi_evaluate_dsm_typed() instead of open-coding _DSM
     evaluation to learn device characteristics (Andy Shevchenko)

   - Tidy multi-function header checks using new PCI_HEADER_TYPE_MASK
     definition (Ilpo Järvinen)

   - Simplify config access error checking in various drivers (Ilpo
     Järvinen)

   - Use pcie_capability_clear_word() (not
     pcie_capability_clear_and_set_word()) when only clearing (Ilpo
     Järvinen)

   - Add pci_get_base_class() to simplify finding devices using base
     class only (ignoring subclass and programming interface) (Sui
     Jingfeng)

   - Add pci_is_vga(), which includes ancient PCI_CLASS_NOT_DEFINED_VGA
     devices from before the Class Code was added to PCI (Sui Jingfeng)

   - Use pci_is_vga() for vgaarb, sysfs "boot_vga", virtio, qxl to
     include ancient VGA devices (Sui Jingfeng)

  Resource management:

   - Make pci_assign_unassigned_resources() non-init because sparc uses
     it after init (Randy Dunlap)

  Driver binding:

   - Retain .remove() and .probe() callbacks (previously __init) because
     sysfs may cause them to be called later (Uwe Kleine-König)

   - Prevent xHCI driver from claiming AMD VanGogh USB3 DRD device, so
     it can be claimed by dwc3 instead (Vicki Pfau)

  PCI device hotplug:

   - Add Ampere Altra Attention Indicator extension driver for acpiphp
     (D Scott Phillips)

  Power management:

   - Quirk VideoPropulsion Torrent QN16e with longer delay after reset
     (Lukas Wunner)

   - Prevent users from overriding drivers that say we shouldn't use
     D3cold (Lukas Wunner)

   - Avoid PME from D3hot/D3cold for AMD Rembrandt and Phoenix USB4
     because wakeup interrupts from those states don't work if amd-pmc
     has put the platform in a hardware sleep state (Mario Limonciello)

  IOMMU:

   - Disable ATS for Intel IPU E2000 devices with invalidation message
     endianness erratum (Bartosz Pawlowski)

  Error handling:

   - Factor out interrupt enable/disable into helpers (Kai-Heng Feng)

  Peer-to-peer DMA:

   - Fix flexible-array usage in struct pci_p2pdma_pagemap in case we
     ever use pagemaps with multiple entries (Gustavo A. R. Silva)

  ASPM:

   - Revert a change that broke when drivers disabled L1 and users later
     enabled an L1.x substate via sysfs, and fix a similar issue when
     users disabled L1 via sysfs (Heiner Kallweit)

  Endpoint framework:

   - Fix double free in __pci_epc_create() (Dan Carpenter)

   - Use IS_ERR_OR_NULL() to simplify endpoint core (Ruan Jinjie)

  Cadence PCIe controller driver:

   - Drop unused "is_rc" member (Li Chen)

  Freescale Layerscape PCIe controller driver:

   - Enable 64-bit addressing in endpoint mode (Guanhua Gao)

  Intel VMD host bridge driver:

   - Fix multi-function header check (Ilpo Järvinen)

  Microsoft Hyper-V host bridge driver:

   - Annotate struct hv_dr_state with __counted_by (Kees Cook)

  NVIDIA Tegra194 PCIe controller driver:

   - Drop setting of LNKCAP_MLW (max link width) since dw_pcie_setup()
     already does this via dw_pcie_link_set_max_link_width() (Yoshihiro
     Shimoda)

  Qualcomm PCIe controller driver:

   - Use PCIE_SPEED2MBS_ENC() to simplify encoding of link speed
     (Manivannan Sadhasivam)

   - Add a .write_dbi2() callback so DBI2 register writes, e.g., for
     setting the BAR size, work correctly (Manivannan Sadhasivam)

   - Enable ASPM for platforms that use 1.9.0 ops, because the PCI core
     doesn't enable ASPM states that haven't been enabled by the
     firmware (Manivannan Sadhasivam)

  Renesas R-Car Gen4 PCIe controller driver:

   - Add DesignWare core support (set max link width, EDMA_UNROLL flag,
     .pre_init(), .deinit(), etc) for use by R-Car Gen4 driver
     (Yoshihiro Shimoda)

   - Add driver and DT schema for DesignWare-based Renesas R-Car Gen4
     controller in both host and endpoint mode (Yoshihiro Shimoda)

  Xilinx NWL PCIe controller driver:

   - Update ECAM size to support 256 buses (Thippeswamy Havalige)

   - Stop setting bridge primary/secondary/subordinate bus numbers,
     since PCI core does this (Thippeswamy Havalige)

  Xilinx XDMA controller driver:

   - Add driver and DT schema for Zynq UltraScale+ MPSoCs devices with
     Xilinx XDMA Soft IP (Thippeswamy Havalige)

  Miscellaneous:

   - Use FIELD_GET()/FIELD_PREP() to simplify and reduce use of _SHIFT
     macros (Ilpo Järvinen, Bjorn Helgaas)

   - Remove logic_outb(), _outw(), outl() duplicate declarations (John
     Sanpe)

   - Replace unnecessary UTF-8 in Kconfig help text because menuconfig
     doesn't render it correctly (Liu Song)"

PCI core API pci_dev_id() can be used to get the BDF number for a pci
device. We don't need to compose it mannually. Use pci_dev_id() to
simplify the code a little bit.

<content type='text'>
Users have reported that s2idle wasn't working on OEM Phoenix systems,
but it was root caused to be because `CONFIG_AMD_PMC` wasn't set in
the distribution kernel config.

To make this more apparent, raise the messaging to err instead of warn.
