drm, drm/xe: Fix xe userptr in the absence of CONFIG_DEVICE_PRIVATE

CONFIG_DEVICE_PRIVATE is not selected by default by some distros,
for example Fedora, and that leads to a regression in the xe driver
since userptr support gets compiled out.

It turns out that DRM_GPUSVM, which is needed for xe userptr support
compiles also without CONFIG_DEVICE_PRIVATE, but doesn't compile
without CONFIG_ZONE_DEVICE.
Exclude the drm_pagemap files from compilation with !CONFIG_ZONE_DEVICE,
and remove the CONFIG_DEVICE_PRIVATE dependency from CONFIG_DRM_GPUSVM and
the xe driver's selection of it, re-enabling xe userptr for those configs.

v2:
- Don't compile the drm_pagemap files unless CONFIG_ZONE_DEVICE is set.
- Adjust the drm_pagemap.h header accordingly.

Drivers: hv: Add CONFIG_HYPERV_VMBUS option

At present VMBus driver is hinged off of CONFIG_HYPERV which entails
lot of builtin code and encompasses too much. It's not always clear
what depends on builtin hv code and what depends on VMBus. Setting
CONFIG_HYPERV as a module and fudging the Makefile to switch to builtin
adds even more confusion. VMBus is an independent module and should have
its own config option. Also, there are scenarios like baremetal dom0/root
where support is built in with CONFIG_HYPERV but without VMBus. Lastly,
there are more features coming down that use CONFIG_HYPERV and add more
dependencies on it.

So, create a fine grained HYPERV_VMBUS option and update Kconfigs for
dependency on VMBus.

rust: drm: Introduce the Tyr driver for Arm Mali GPUs

Add a Rust driver for ARM Mali CSF-based GPUs. It is a port of Panthor
and therefore exposes Panthor's uAPI and name to userspace, and the
product of a joint effort between Collabora, Arm and Google engineers.

The aim is to incrementally develop Tyr with the abstractions that are
currently available until it is consider to be in parity with Panthor
feature-wise.

The development of Tyr itself started in January, after a few failed
attempts of converting Panthor piecewise through a mix of Rust and C
code. There is a downstream branch that's much further ahead in terms of
capabilities than this initial patch.

The downstream code is capable of booting the MCU, doing sync VM_BINDS
through the work-in-progress GPUVM abstraction and also doing (trivial)
submits through Asahi's drm_scheduler and dma_fence abstractions. So
basically, most of what one would expect a modern GPU driver to do,
except for power management and some other very important adjacent
pieces. It is not at the point where submits can correctly deal with
dependencies, or at the point where it can rotate access to the GPU
hardware fairly through a software scheduler, but that is simply a
matter of writing more code.

This first patch, however, only implements a subset of the current
features available downstream, as the rest is not implementable without
pulling in even more abstractions. In particular, a lot of things depend
on properly mapping memory on a given VA range, which itself depends on
the GPUVM abstraction that is currently work-in-progress. For this
reason, we still cannot boot the MCU and thus, cannot do much for the
moment.

This constitutes a change in the overall strategy that we have been
using to develop Tyr so far. By submitting small parts of the driver
upstream iteratively, we aim to:

a) evolve together with Nova and rvkms, hopefully reducing regressions
due to upstream changes (that may break us because we were not there, in
the first place)

b) prove any work-in-progress abstractions by having them run on a real
driver and hardware and,

c) provide a reason to work on and review said abstractions by providing
a user, which would be tyr itself.

Despite its limited feature-set, we offer IGT tests. It is only tested
on the rk3588, so any other SoC is probably not going to work at all for
now.

The skeleton is basically taken from Nova and also
rust_platform_driver.rs.

Lastly, the name "Tyr" is inspired by Norse mythology, reflecting ARM's
tradition of naming their GPUs after Nordic mythological figures and
places.

Pull pci updates from Bjorn Helgaas:
"Enumeration:

- Print the actual delay time in pci_bridge_wait_for_secondary_bus()
instead of assuming it was 1000ms (Wilfred Mallawa)

- Revert 'iommu/amd: Prevent binding other PCI drivers to IOMMU PCI
devices', which broke resume from system sleep on AMD platforms and
has been fixed by other commits (Lukas Wunner)

Resource management:

- Remove mtip32xx use of pcim_iounmap_regions(), which is deprecated
and unnecessary (Philipp Stanner)

- Remove pcim_iounmap_regions() and pcim_request_region_exclusive()
and related flags since all uses have been removed (Philipp
Stanner)

- Rework devres 'request' functions so they are no longer 'hybrid',
i.e., their behavior no longer depends on whether
pcim_enable_device or pci_enable_device() was used, and remove
related code (Philipp Stanner)

- Warn (not BUG()) about failure to assign optional resources (Ilpo
Järvinen)

Error handling:

- Log the DPC Error Source ID only when it's actually valid (when
ERR_FATAL or ERR_NONFATAL was received from a downstream device)
and decode into bus/device/function (Bjorn Helgaas)

- Determine AER log level once and save it so all related messages
use the same level (Karolina Stolarek)

- Use KERN_WARNING, not KERN_ERR, when logging PCIe Correctable
Errors (Karolina Stolarek)

- Ratelimit PCIe Correctable and Non-Fatal error logging, with sysfs
controls on interval and burst count, to avoid flooding logs and
RCU stall warnings (Jon Pan-Doh)

Power management:

- Increment PM usage counter when probing reset methods so we don't
try to read config space of a powered-off device (Alex Williamson)

- Set all devices to D0 during enumeration to ensure ACPI opregion is
connected via _REG (Mario Limonciello)

Power control:

- Rename pwrctrl Kconfig symbols from 'PWRCTL' to 'PWRCTRL' to match
the filename paths. Retain old deprecated symbols for
compatibility, except for the pwrctrl slot driver
(PCI_PWRCTRL_SLOT) (Johan Hovold)

- When unregistering pwrctrl, cancel outstanding rescan work before
cleaning up data structures to avoid use-after-free issues (Brian
Norris)

Bandwidth control:

- Simplify link bandwidth controller by replacing the count of Link
Bandwidth Management Status (LBMS) events with a PCI_LINK_LBMS_SEEN
flag (Ilpo Järvinen)

- Update the Link Speed after retraining, since the Link Speed may
have changed (Ilpo Järvinen)

PCIe native device hotplug:

- Ignore Presence Detect Changed caused by DPC.

pciehp already ignores Link Down/Up events caused by DPC, but on
slots using in-band presence detect, DPC causes a spurious Presence
Detect Changed event (Lukas Wunner)

- Ignore Link Down/Up caused by Secondary Bus Reset.

On hotplug ports using in-band presence detect, the reset causes a
Presence Detect Changed event, which mistakenly caused teardown and
re-enumeration of the device. Drivers may need to annotate code
that resets their device (Lukas Wunner)

Virtualization:

- Add an ACS quirk for Loongson Root Ports that don't advertise ACS
but don't allow peer-to-peer transactions between Root Ports; the
quirk allows each Root Port to be in a separate IOMMU group (Huacai
Chen)

Endpoint framework:

- For fixed-size BARs, retain both the actual size and the possibly
larger size allocated to accommodate iATU alignment requirements
(Jerome Brunet)

- Simplify ctrl/SPAD space allocation and avoid allocating more space
than needed (Jerome Brunet)

- Correct MSI-X PBA offset calculations for DesignWare and Cadence
endpoint controllers (Niklas Cassel)

- Align the return value (number of interrupts) encoding for
pci_epc_get_msi()/pci_epc_ops::get_msi() and
pci_epc_get_msix()/pci_epc_ops::get_msix() (Niklas Cassel)

- Align the nr_irqs parameter encoding for
pci_epc_set_msi()/pci_epc_ops::set_msi() and
pci_epc_set_msix()/pci_epc_ops::set_msix() (Niklas Cassel)

Common host controller library:

- Convert pci-host-common to a library so platforms that don't need
native host controller drivers don't need to include these helper
functions (Manivannan Sadhasivam)

Apple PCIe controller driver:

- Extract ECAM bridge creation helper from pci_host_common_probe() to
separate driver-specific things like MSI from PCI things (Marc
Zyngier)

- Dynamically allocate RID-to_SID bitmap to prepare for SoCs with
varying capabilities (Marc Zyngier)

- Skip ports disabled in DT when setting up ports (Janne Grunau)

- Add t6020 compatible string (Alyssa Rosenzweig)

- Add T602x PCIe support (Hector Martin)

- Directly set/clear INTx mask bits because T602x dropped the
accessors that could do this without locking (Marc Zyngier)

- Move port PHY registers to their own reg items to accommodate
T602x, which moves them around; retain default offsets for existing
DTs that lack phy%d entries with the reg offsets (Hector Martin)

- Stop polling for core refclk, which doesn't work on T602x and the
bootloader has already done anyway (Hector Martin)

- Use gpiod_set_value_cansleep() when asserting PERST# in probe
because we're allowed to sleep there (Hector Martin)

Cadence PCIe controller driver:

- Drop a runtime PM 'put' to resolve a runtime atomic count underflow
(Hans Zhang)

- Make the cadence core buildable as a module (Kishon Vijay Abraham I)

- Add cdns_pcie_host_disable() and cdns_pcie_ep_disable() for use by
loadable drivers when they are removed (Siddharth Vadapalli)

Freescale i.MX6 PCIe controller driver:

- Apply link training workaround only on IMX6Q, IMX6SX, IMX6SP
(Richard Zhu)

- Remove redundant dw_pcie_wait_for_link() from
imx_pcie_start_link(); since the DWC core does this, imx6 only
needs it when retraining for a faster link speed (Richard Zhu)

- Toggle i.MX95 core reset to align with PHY powerup (Richard Zhu)

- Set SYS_AUX_PWR_DET to work around i.MX95 ERR051624 erratum: in
some cases, the controller can't exit 'L23 Ready' through Beacon or
PERST# deassertion (Richard Zhu)

- Clear GEN3_ZRXDC_NONCOMPL to work around i.MX95 ERR051586 erratum:
controller can't meet 2.5 GT/s ZRX-DC timing when operating at 8
GT/s, causing timeouts in L1 (Richard Zhu)

- Wait for i.MX95 PLL lock before enabling controller (Richard Zhu)

- Save/restore i.MX95 LUT for suspend/resume (Richard Zhu)

Mobiveil PCIe controller driver:

- Return bool (not int) for link-up check in
mobiveil_pab_ops.link_up() and layerscape-gen4, mobiveil (Hans
Zhang)

NVIDIA Tegra194 PCIe controller driver:

- Create debugfs directory for 'aspm_state_cnt' only when
CONFIG_PCIEASPM is enabled, since there are no other entries (Hans
Zhang)

Qualcomm PCIe controller driver:

- Reorder rockchip_pci_core_rsts because
reset_control_bulk_deassert() deasserts in reverse order, to fix a
link training regression (Jensen Huang)

- Mark RK3399 as being capable of raising INTx interrupts (Niklas
Cassel)

Rockchip DesignWare PCIe controller driver:

- Check only PCIE_LINKUP, not LTSSM status, to determine whether the
link is up (Shawn Lin)

- Increase N_FTS (used in L0s->L0 transitions) and enable ASPM L0s
for Root Complex and Endpoint modes (Shawn Lin)

- Hide the broken ATS Capability in rockchip_pcie_ep_init() instead

resets non-sticky registers (Shawn Lin)

- Call phy_power_off() before phy_exit() in rockchip_pcie_phy_deinit()
(Diederik de Haas)

drm/ttm: Fix compile error when CONFIG_SHMEM is not set

When CONFIG_SHMEM is not set, the following compiler error occurs:

ld: vmlinux.o: in function `ttm_backup_backup_page':
(.text+0x10363bc): undefined reference to `shmem_writeout'
make[3]: *** [/work/build/trace/nobackup/linux.git/scripts/Makefile.vmlinux:91: vmlinux.unstripped] Error 1

This is due to the replacement of writepage and calling swap_writeout()
and shmem_writeout() directly. The issue is that when CONFIG_SHMEM is
not defined, shmem_writeout() is also not defined.

The function ttm_backup_backup_page() called mapping->a_ops->writepage()
which was then changed to call shmem_writeout() directly.

Even before commit 84798514db50 ("mm: Remove swap_writepage() and
shmem_writepage()"), it didn't make sense to call anything other than
shmem_writeout() as the ttm_backup deals only with shmem folios.

Have DRM_TTM config option select SHMEM to guarantee that
shmem_writeout() is available.

drm: nova-drm: add initial driver skeleton

Add the initial nova-drm driver skeleton.

nova-drm is connected to nova-core through the auxiliary bus and
implements the DRM parts of the nova driver stack.

For now, it implements the fundamental DRM abstractions, i.e. creates a
DRM device and registers it, exposing a three sample IOCTLs.

DRM_IOCTL_NOVA_GETPARAM
- provides the PCI bar size from the bar that maps the GPUs VRAM
from nova-core

DRM_IOCTL_NOVA_GEM_CREATE
- creates a new dummy DRM GEM object and returns a handle

DRM_IOCTL_NOVA_GEM_INFO
- provides metadata for the DRM GEM object behind a given handle

I implemented a small userspace test suite [1] that utilizes this
interface.

PCI: Add CONFIG_MMU dependency

It turns out that there are no platforms that have PCI but don't have an
MMU, so adding a Kconfig dependency on CONFIG_PCI simplifies build testing
kernels for those platforms a lot, and avoids a lot of inadvertent build
regressions.

Add a dependency for CONFIG_PCI and remove all the ones for PCI specific
device drivers that are currently marked not having it.

There are a few platforms that have an optional MMU, but they usually
cannot have PCI at all. The one exception is Coldfire MCF54xx, but this is
mainly for historic reasons, and anyone using those chips should really use
the MMU these days.

Merge tag 'drm-next-2025-03-28' of https://gitlab.freedesktop.org/drm/kernel

Pull drm updates from Dave Airlie:
"Outside of drm there are some rust patches from Danilo who maintains
that area in here, and some pieces for drm header check tests.

The major things in here are a new driver supporting the touchbar
displays on M1/M2, the nova-core stub driver which is just the vehicle
for adding rust abstractions and start developing a real driver inside
of.

xe adds support for SVM with a non-driver specific SVM core
abstraction that will hopefully be useful for other drivers, along
with support for shrinking for TTM devices. I'm sure xe and AMD
support new devices, but the pipeline depth on these things is hard to
know what they end up being in the marketplace!
