drm/tilcdc: Fix removal actions in case of failed probe
The drm_kms_helper_poll_fini() and drm_atomic_helper_shutdown() helpers
should only be called when the device has been successfully registered.
Currently, these functions are called unconditionally in tilcdc_fini(),
which causes warnings during probe deferral scenarios.

Fix this by rewriting the failed probe cleanup path using the standard

only called on successfully initialized resources. Additionally, remove
the now-unnecessary is_registered flag.

drm/amd/display: shrink struct members
On a 32-bit ARM system, the audio_decoder struct ends up being too large
for dp_retrain_link_dp_test.
link_dp_cts.c:157:1: error: the frame size of 1328 bytes is larger than
1280 bytes [-Werror=frame-larger-than=]
This is mitigated by shrinking the members of the struct and avoids
having to deal with dynamic allocation.
feed_back_divider is assigned but otherwise unused. Remove both.
pixel_repetition looks like it should be a bool since it's only ever
assigned to 1. But there are checks for 2 and 4. Reduce to uint8_t.
Remove ss_percentage_divider. Unused.
Shrink refresh_rate as it gets assigned to at most a 3 digit integer
value.

drm/amdkfd: Trap handler support for expert scheduling mode
The trap may be entered with dependency checking disabled.
Wait for dependency counters and save/restore scheduling mode.
v2:
Use ttmp1 instead of ttmp11. ttmp11 is not zero-initialized.
While the trap handler does zero this field before use, a user-mode
second-level trap handler could not rely on this being zero when
using an older kernel mode driver.
v3:
Use ttmp11 primarily but copy to ttmp1 before jumping to the
second level trap handler. ttmp1 is inspectable by a debugger.
Unexpected bits in the unused space may regress existing software.

VFIO updates for v6.19-rc1
- Move libvfio selftest artifacts in preparation of more tightly
coupled integration with KVM selftests. (David Matlack)
- Fix comment typo in mtty driver. (Chu Guangqing)
- Support for new hardware revision in the hisi_acc vfio-pci variant
driver where the migration registers can now be accessed via the PF.
When enabled for this support, the full BAR can be exposed to the
user. (Longfang Liu)
- Fix vfio cdev support for VF token passing, using the correct size
for the kernel structure, thereby actually allowing userspace to
provide a non-zero UUID token. Also set the match token callback for
the hisi_acc, fixing VF token support for this this vfio-pci variant
driver. (Raghavendra Rao Ananta)
- Introduce internal callbacks on vfio devices to simplify and
consolidate duplicate code for generating VFIO_DEVICE_GET_REGION_INFO
data, removing various ioctl intercepts with a more structured
solution. (Jason Gunthorpe)
- Introduce dma-buf support for vfio-pci devices, allowing MMIO regions
to be exposed through dma-buf objects with lifecycle managed through
move operations. This enables low-level interactions such as a
vfio-pci based SPDK drivers interacting directly with dma-buf capable
RDMA devices to enable peer-to-peer operations. IOMMUFD is also now
able to build upon this support to fill a long standing feature gap
versus the legacy vfio type1 IOMMU backend with an implementation of
P2P support for VM use cases that better manages the lifecycle of the
P2P mapping. (Leon Romanovsky, Jason Gunthorpe, Vivek Kasireddy)
- Convert eventfd triggering for error and request signals to use RCU
mechanisms in order to avoid a 3-way lockdep reported deadlock issue.
(Alex Williamson)
- Fix a 32-bit overflow introduced via dma-buf support manifesting with
large DMA buffers. (Alex Mastro)
- Convert nvgrace-gpu vfio-pci variant driver to insert mappings on
fault rather than at mmap time. This conversion serves both to make
use of huge PFNMAPs but also to both avoid corrected RAS events
during reset by now being subject to vfio-pci-core's use of
unmap_mapping_range(), and to enable a device readiness test after
reset. (Ankit Agrawal)
- Refactoring of vfio selftests to support multi-device tests and split
code to provide better separation between IOMMU and device objects.
This work also enables a new test suite addition to measure parallel
device initialization latency. (David Matlack)

Pull VFIO updates from Alex Williamson:
- Move libvfio selftest artifacts in preparation of more tightly
coupled integration with KVM selftests (David Matlack)
- Fix comment typo in mtty driver (Chu Guangqing)
- Support for new hardware revision in the hisi_acc vfio-pci variant
driver where the migration registers can now be accessed via the PF.
When enabled for this support, the full BAR can be exposed to the
user (Longfang Liu)
- Fix vfio cdev support for VF token passing, using the correct size
for the kernel structure, thereby actually allowing userspace to
provide a non-zero UUID token. Also set the match token callback for
the hisi_acc, fixing VF token support for this this vfio-pci variant
driver (Raghavendra Rao Ananta)
- Introduce internal callbacks on vfio devices to simplify and
consolidate duplicate code for generating VFIO_DEVICE_GET_REGION_INFO
data, removing various ioctl intercepts with a more structured
solution (Jason Gunthorpe)
- Introduce dma-buf support for vfio-pci devices, allowing MMIO regions
to be exposed through dma-buf objects with lifecycle managed through
move operations. This enables low-level interactions such as a
vfio-pci based SPDK drivers interacting directly with dma-buf capable
RDMA devices to enable peer-to-peer operations. IOMMUFD is also now
able to build upon this support to fill a long standing feature gap
versus the legacy vfio type1 IOMMU backend with an implementation of
P2P support for VM use cases that better manages the lifecycle of the
P2P mapping (Leon Romanovsky, Jason Gunthorpe, Vivek Kasireddy)
- Convert eventfd triggering for error and request signals to use RCU
mechanisms in order to avoid a 3-way lockdep reported deadlock issue
(Alex Williamson)
- Fix a 32-bit overflow introduced via dma-buf support manifesting with
large DMA buffers (Alex Mastro)
- Convert nvgrace-gpu vfio-pci variant driver to insert mappings on
fault rather than at mmap time. This conversion serves both to make
use of huge PFNMAPs but also to both avoid corrected RAS events
during reset by now being subject to vfio-pci-core's use of
unmap_mapping_range(), and to enable a device readiness test after
reset (Ankit Agrawal)
- Refactoring of vfio selftests to support multi-device tests and split
code to provide better separation between IOMMU and device objects.
This work also enables a new test suite addition to measure parallel
device initialization latency (David Matlack)

drm/nouveau/gsp: Allocate fwsec-sb at boot
At the moment - the memory allocation for fwsec-sb is created as-needed and
is released after being used. Typically this is at some point well after
driver load, which can cause runtime suspend/resume to initially work on
driver load but then later fail on a machine that has been running for long
enough with sufficiently high enough memory pressure:

The reason this happens is because the fwsec-sb firmware image only
supports being booted from a contiguous coherent sysmem allocation. If a
system runs into enough memory fragmentation from memory pressure, such as
what can happen on systems with low amounts of memory, this can lead to a
situation where it later becomes impossible to find space for a large
enough contiguous allocation to hold fwsec-sb. This causes us to fail to
boot the firmware image, causing the GPU to fail booting and causing the
driver to fail.
Since this firmware can't use non-contiguous allocations, the best solution
to avoid this issue is to simply allocate the memory for fwsec-sb during
initial driver-load, and reuse the memory allocation when fwsec-sb needs to
be used. We then release the memory allocations on driver unload.

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Enable host bridge emulation for PCI_DOMAINS_GENERIC platforms (Dan
Williams)
- Switch vmd from custom domain number allocator to the common
allocator to prevent a potential race with new non-VMD buses (Dan
Williams)
- Enable Precision Time Measurement (PTM) only if device advertises
support for a relevant role, to prevent invalid PTM Requests that
cause ACS violations that are reported as AER Uncorrectable
Non-Fatal errors (Mika Westerberg)
Resource management:
- Prevent resource tree corruption when BAR resize fails (Ilpo
Järvinen)
- Restore BARs to the original size if a BAR resize fails (Ilpo
Järvinen)
- Remove BAR release from BAR resize attempts by the xe, i915, and
amdgpu drivers so the PCI core can restore BARs if the resize fails
(Ilpo Järvinen)
- Move Resizable BAR code to rebar.c (Ilpo Järvinen)
- Add pci_rebar_size_supported() and use it in i915 and xe (Ilpo
Järvinen)
- Add pci_rebar_get_max_size() and use it in xe and amdgpu (Ilpo
Järvinen)
Power management and error handling:
- For drivers using PCI legacy suspend, save config state at suspend
so that state (not any earlier state from enumeration, probe, or
error recovery) will be restored when resuming (Lukas Wunner)
- For devices with no driver or a driver that lacks power management,
save config state at hibernate so that state (not any earlier state
from enumeration, probe, or error recovery) will be restored when
resuming (Lukas Wunner)
- Save device config space on device addition, before driver binding,
so error recovery works more reliably (Lukas Wunner)
- Drop pci_save_state() from several drivers that no longer need it
since the PCI core always does it and pci_restore_state() no longer
invalidates the saved state (Lukas Wunner)
- Document use of pci_save_state() by drivers to capture the state
they want restored during error recovery (Lukas Wunner)
Power control:
- Add a struct pci_ops.assert_perst() function pointer to
assert/deassert PCIe PERST# and implement it for the qcom driver
(Krishna Chaitanya Chundru)

Apple PCIe controller driver:
- Move struct pci_host_bridge allocation from pci_host_common_init()
to callers, which significantly simplifies pcie-apple (Marc
Zyngier)
Broadcom STB PCIe controller driver:
- Disable advertising ASPM L0s support correctly (Jim Quinlan)
- Add a panic/die handler to print diagnostic info in case PCIe
caused an unrecoverable abort (Jim Quinlan)
Cadence PCIe controller driver:
- Add module support for Cadence platform host and endpoint
controller driver (Manikandan K Pillai)

Rockchip DesignWare PCIe controller driver:
- Add Rockchip RK3528 compatible strings in DT binding (Yao Zi)
STMicroelectronics STM32MP25 PCIe controller driver:
- Fix a race between link training and endpoint register
initialization (Christian Bruel)
- Align endpoint allocations to match the ATU requirements (Christian
Bruel)
Synopsys DesignWare PCIe controller driver:
- Clear L1 PM Substate Capability 'Supported' bits unless glue driver
says it's supported, which prevents users from enabling non-working
L1SS. Currently only qcom and tegra194 support L1SS (Bjorn Helgaas)
- Remove now-superfluous L1SS disable code from tegra194 (Bjorn
Helgaas)
- Configure L1SS support in dw-rockchip when DT says
'supports-clkreq' (Shawn Lin)
TI Keystone PCIe controller driver:
- Fail the probe instead of silently succeeding if ks_pcie_of_data
didn't specify Root Complex or Endpoint mode (Siddharth Vadapalli)
- Make keystone buildable as a loadable module, except on ARM32 where
hook_fault_code() is __init (Siddharth Vadapalli)"

drm/i915/color: Add 3D LUT to color pipeline
Add helpers to program the 3D LUT registers and arm them. LUT_3D_READY in LUT_3D_CLT is cleared off by the HW once the LUT buffer is loaded into it's internal working RAM. So by the time we try to load/commit new values, we expect it to be cleared off. If not, log an error and return without writing new values. Do it only when writing with MMIO. There is no way to read register within DSB execution. v2: - Add information regarding LUT_3D_READY to commit message (Jani) - Log error instead of a drm_warn and return without committing changes if 3DLUT HW is not ready to accept new values. - Refactor intel_color_crtc_has_3dlut() Also remove Gen10 check (Suraj) v3: - Addressed review comments (Suraj) Reviewed-by: Suraj Kandpal <suraj.kandpal@intel.com> Signed-off-by: Chaitanya Kumar Borah <chaitanya.kumar.borah@intel.com> Signed-off-by: Uma Shankar <uma.shankar@intel.com> Link: https://patch.msgid.link/20251203085211.3663374-15-uma.shankar@intel.com Signed-off-by: Jani Nikula <jani.nikula@intel.com> |
