Merge branch 'pci/controller/qcom' (2024-03-12 12:14:26 -0500)
----------------------------------------------------------------
Enumeration:
- Consolidate interrupt related code in irq.c (Ilpo Järvinen)
- Reduce kernel size by replacing sysfs resource macros with functions
(Ilpo Järvinen)
- Reduce kernel size by compiling sysfs support only when CONFIG_SYSFS=y
(Lukas Wunner)
- Avoid using Extended Tags on 3ware-9650SE Root Port to work around an
apparent hardware defect (Jörg Wedekind)
Resource management:
- Fix an MMIO mapping leak in pci_iounmap() (Philipp Stanner)
- Move pci_iomap.c and other PCI-specific devres code to drivers/pci
(Philipp Stanner)
- Consolidate PCI devres code in devres.c (Philipp Stanner)
Power management:
- Avoid D3cold on Asus B1400 PCI-NVMe bridge, where firmware doesn't know
how to return correctly to D0, and remove previous quirk that wasn't as
specific (Daniel Drake)
- Allow runtime PM when the driver enables it but doesn't need any
runtime PM callbacks (Raag Jadav)
- Drain runtime-idle callbacks before driver removal to avoid races
between .remove() and .runtime_idle(), which caused intermittent page
faults when the rtsx .runtime_idle() accessed registers that its
.remove() had already unmapped (Rafael J. Wysocki)
Virtualization:
- Avoid Secondary Bus Reset on LSI FW643 so it can be assigned to VMs
with VFIO, e.g., for professional audio software on many Apple
machines, at the cost of leaking state between VMs (Edmund Raile)
Error handling:
- Print all logged TLP Prefixes, not just the first, after AER or DPC
errors (Ilpo Järvinen)
- Quirk the DPC PIO log size for Intel Raptor Lake Root Ports, which
still don't advertise a legal size (Paul Menzel)
- Ignore expected DPC Surprise Down errors on hot removal (Smita
Koralahalli)
- Block runtime suspend while handling AER errors to avoid races that
prevent the device form being resumed from D3hot (Stanislaw Gruszka)
Peer-to-peer DMA:
- Use atomic XA allocation in RCU read section (Christophe JAILLET)
ASPM:
- Collect bits of ASPM-related code that we need even without
CONFIG_PCIEASPM into aspm.c (David E. Box)
- Save/restore L1 PM Substates config for suspend/resume (David E. Box)
- Update save_save when ASPM config is changed, so a .slot_reset() during
error recovery restores the changed config, not the .probe()-time
config (Vidya Sagar)
Endpoint framework:
- Refactor and improve pci_epf_alloc_space() API (Niklas Cassel)
- Clean up endpoint BAR descriptions (Niklas Cassel)
- Fix ntb_register_device() name leak in error path (Yang Yingliang)
- Return actual error code for pci_vntb_probe() failure (Yang Yingliang)
Broadcom STB PCIe controller driver:
- Fix MDIO write polling, which previously never waited for completion
(Jonathan Bell)
Cadence PCIe endpoint driver:
- Clear the ARI "Next Function Number" of last function (Jasko-EXT
Wojciech)
Freescale i.MX6 PCIe controller driver:
- Simplify by replacing switch statements with function pointers for
different hardware variants (Frank Li)
- Simplify by using clk_bulk*() API (Frank Li)
- Remove redundant DT clock and reg/reg-name details (Frank Li)
- Add i.MX95 DT and driver support for both Root Complex and Endpoint
mode (Frank Li)
Microsoft Hyper-V host bridge driver:
- Reduce memory usage by limiting ring buffer size to 16KB instead of 4
pages (Michael Kelley)
Qualcomm PCIe controller driver:
- Add X1E80100 DT and driver support (Abel Vesa)
- Add DT 'required-opps' for SoCs that require a minimum performance
level (Johan Hovold)
- Make DT 'msi-map-mask' optional, depending on how MSI interrupts are
mapped (Johan Hovold)
- Disable ASPM L0s for sc8280xp, sa8540p and sa8295p because the PHY
configuration isn't tuned correctly for L0s (Johan Hovold)
- Split dt-binding qcom,pcie.yaml into qcom,pcie-common.yaml and separate
files for SA8775p, SC7280, SC8180X, SC8280XP, SM8150, SM8250, SM8350,
SM8450, SM8550 for easier reviewing (Krzysztof Kozlowski)
- Enable BDF to SID translation by disabling bypass mode (Manivannan
Sadhasivam)
- Add endpoint MHI support for Snapdragon SA8775P SoC (Mrinmay Sarkar)
Synopsys DesignWare PCIe controller driver:
- Allocate 64-bit MSI address if no 32-bit address is available (Ajay
Agarwal)
- Fix endpoint Resizable BAR to actually advertise the required 1MB size
(Niklas Cassel)
MicroSemi Switchtec management driver:
- Release resources if the .probe() fails (Christophe JAILLET)
Miscellaneous:
- Make pcie_port_bus_type const (Ricardo B. Marliere)
