git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci 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: - Add OF support for parsing DT 'eq-presets-<N>gts' property for lane equalization presets (Krishna Chaitanya Chundru) - Read Maximum Link Width from the Link Capabilities register if DT lacks 'num-lanes' property (Krishna Chaitanya Chundru) - Add Physical Layer 64 GT/s Capability ID and register offsets for 8, 32, and 64 GT/s lane equalization registers (Krishna Chaitanya Chundru) - Add generic dwc support for configuring lane equalization presets (Krishna Chaitanya Chundru) - Add DT and driver support for PCIe on IPQ5018 SoC (Nitheesh Sekar) Renesas R-Car PCIe controller driver: - Describe endpoint BAR 4 as being fixed size (Jerome Brunet) - Document how to obtain R-Car V4H (r8a779g0) controller firmware (Yoshihiro Shimoda) Rockchip 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 of rockchip_pcie_ep_pre_init() so it stays hidden after PERST# resets non-sticky registers (Shawn Lin) - Call phy_power_off() before phy_exit() in rockchip_pcie_phy_deinit() (Diederik de Haas) Synopsys DesignWare PCIe controller driver: - Set PORT_LOGIC_LINK_WIDTH to one lane to make initial link training more robust; this will not affect the intended link width if all lanes are functional (Wenbin Yao) - Return bool (not int) for link-up check in dw_pcie_ops.link_up() and armada8k, dra7xx, dw-rockchip, exynos, histb, keembay, keystone, kirin, meson, qcom, qcom-ep, rcar_gen4, spear13xx, tegra194, uniphier, visconti (Hans Zhang) - Add debugfs support for exposing DWC device-specific PTM context (Manivannan Sadhasivam) TI J721E PCIe driver: - Make j721e buildable as a loadable and removable module (Siddharth Vadapalli) - Fix j721e host/endpoint dependencies that result in link failures in some configs (Arnd Bergmann) Device tree bindings: - Add qcom DT binding for 'global' interrupt (PCIe controller and link-specific events) for ipq8074, ipq8074-gen3, ipq6018, sa8775p, sc7280, sc8180x sdm845, sm8150, sm8250, sm8350 (Manivannan Sadhasivam) - Add qcom DT binding for 8 MSI SPI interrupts for msm8998, ipq8074, ipq8074-gen3, ipq6018 (Manivannan Sadhasivam) - Add dw rockchip DT binding for rk3576 and rk3562 (Kever Yang) - Correct indentation and style of examples in brcm,stb-pcie, cdns,cdns-pcie-ep, intel,keembay-pcie-ep, intel,keembay-pcie, microchip,pcie-host, rcar-pci-ep, rcar-pci-host, xilinx-versal-cpm (Krzysztof Kozlowski) - Convert Marvell EBU (dove, kirkwood, armada-370, armada-xp) and armada8k from text to schema DT bindings (Rob Herring) - Remove obsolete .txt DT bindings for content that has been moved to schemas (Rob Herring) - Add qcom DT binding for MHI registers in IPQ5332, IPQ6018, IPQ8074 and IPQ9574 (Varadarajan Narayanan) - Convert v3,v360epc-pci from text to DT schema binding (Rob Herring) - Change microchip,pcie-host DT binding to be 'dma-noncoherent' since PolarFire may be configured that way (Conor Dooley) Miscellaneous: - Drop 'pci' suffix from intel_mid_pci.c filename to match similar files (Andy Shevchenko) - All platforms with PCI have an MMU, so add PCI Kconfig dependency on MMU to simplify build testing and avoid inadvertent build regressions (Arnd Bergmann) - Update Krzysztof Wilczyński's email address in MAINTAINERS (Krzysztof Wilczyński) - Update Manivannan Sadhasivam's email address in MAINTAINERS (Manivannan Sadhasivam)" * tag 'pci-v6.16-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci: (147 commits) MAINTAINERS: Update Manivannan Sadhasivam email address PCI: j721e: Fix host/endpoint dependencies PCI: j721e: Add support to build as a loadable module PCI: cadence-ep: Introduce cdns_pcie_ep_disable() helper for cleanup PCI: cadence-host: Introduce cdns_pcie_host_disable() helper for cleanup PCI: cadence: Add support to build pcie-cadence library as a kernel module MAINTAINERS: Update Krzysztof Wilczyński email address PCI: Remove unnecessary linesplit in __pci_setup_bridge() PCI: WARN (not BUG()) when we fail to assign optional resources PCI: Remove unused pci_printk() PCI: qcom: Replace PERST# sleep time with proper macro PCI: dw-rockchip: Replace PERST# sleep time with proper macro PCI: host-common: Convert to library for host controller drivers PCI/ERR: Remove misleading TODO regarding kernel panic PCI: cadence: Remove duplicate message code definitions PCI: endpoint: Align pci_epc_set_msix(), pci_epc_ops::set_msix() nr_irqs encoding PCI: endpoint: Align pci_epc_set_msi(), pci_epc_ops::set_msi() nr_irqs encoding PCI: endpoint: Align pci_epc_get_msix(), pci_epc_ops::get_msix() return value encoding PCI: endpoint: Align pci_epc_get_msi(), pci_epc_ops::get_msi() return value encoding PCI: cadence-ep: Correct PBA offset in .set_msix() callback ...

2025-05-12drm/sitronix: move tiny Sitronix drivers to their own subdirMarcus Folkesson

2025-05-12drm/tiny: panel-mipi-dbi: Use drm_client_setup_with_fourcc()Fabio Estevam
Since commit 559358282e5b ("drm/fb-helper: Don't use the preferred depth for the BPP default"), RGB565 displays such as the CFAF240320X no longer render correctly: colors are distorted and the content is shown twice horizontally. This regression is due to the fbdev emulation layer defaulting to 32 bits per pixel, whereas the display expects 16 bpp (RGB565). As a result, the framebuffer data is incorrectly interpreted by the panel. Fix the issue by calling drm_client_setup_with_fourcc() with a format explicitly selected based on the display's bits-per-pixel value. For 16 bpp, use DRM_FORMAT_RGB565; for other values, fall back to the previous behavior. This ensures that the allocated framebuffer format matches the hardware expectations, avoiding color and layout corruption. Tested on a CFAF240320X display with an RGB565 configuration, confirming correct colors and layout after applying this patch.

2025-05-09drm/cirrus: Use non-hybrid PCI devres APIPhilipp Stanner
cirrus enables its PCI device with pcim_enable_device(). This, implicitly, switches the function pci_request_regions() into managed mode, where it becomes a devres function. The PCI subsystem wants to remove this hybrid nature from its interfaces. To do so, users of the aforementioned combination of functions must be ported to non-hybrid functions. Replace the call to sometimes-managed pci_request_regions() with one to the always-managed pcim_request_all_regions().

2025-04-23PCI: Add CONFIG_MMU dependencyArnd Bergmann
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.

2025-04-01drm/cirrus-qemu: Use framebuffer format as-is, drop adjustmentsThomas Zimmermann
Remove internal adjustments to framebuffer format from cirrus-qemu driver. The driver did this to support higher resolutions by reducing the per-pixel memory consumption. DRM has a policy of exporting formats as they are implemented in hardware. So avoid internal adjustments if possible. Also remove the call to drm_fb_blit() from cirrus-qemu. The helper is useful if source and destination format are not known beforehand. This is not the case for cirrus-qemu. This change effectively reduces the maximum available resolution to 800x600 at 32 bpp. A maximum scanline pitch of 4095 byte prevents 1024 pixels per scanline at 32 bpp. Higher resolutions are possible at lower bit depths, but are currently not supported by userspace. When cirrus-qemu currently reduced the internal bit depth to support higher resolutions, it trades resolution for bit depth and CPU time. Converting from 32-bit colors has a significant runtime overhead, as outlined at [1]. Avoiding color-format adjustments also avoids this tradeoff. v2: - expand commit message (Gerd) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Gerd Hoffmann <kraxel@redhat.com> Link: https://lore.kernel.org/dri-devel/20250325110407.81107-1-tzimmermann@suse.de/ # 1 Link: https://lore.kernel.org/r/20250328091821.195061-4-tzimmermann@suse.de
2025-04-01drm/cirrus-qemu: Stricter mode validationThomas Zimmermann
Implement strict checking of a display mode's minimum scanline pitch in cirrus_mode_config_mode_valid(). Sort out all modes that possibly overflow the maximum pitch. The current validation only tests against a display mode's minimum requirements for video memory. Only atomic_check later tests against the pitch limit before programming the framebuffer. The problem is that user-space compositors do not handle this gracefully. If atomic_check fails to validate the scanline pitch and returns an error, the compositor, namely Weston, does nothing and the display remains stale. Ruling out display modes that possibly overflow the pitch avoids this problem. With only 4 MiB of video memory available, this effectively limits horizontal resolution to 800 pixels. But with cirrus-qemu being low-end and obsolete, this is probably not an issue in practice. Better alternatives are available in qemu.

2025-03-03drm/tiny: add driver for Apple Touch Bars in x86 MacsKerem Karabay
The Touch Bars found on x86 Macs support two USB configurations: one where the device presents itself as a HID keyboard and can display predefined sets of keys, and one where the operating system has full control over what is displayed. This commit adds support for the display functionality of the second configuration. Functionality for the first configuration has been merged in the HID tree. Note that this driver has only been tested on T2 Macs, and only includes the USB device ID for these devices. Testing on T1 Macs would be appreciated. Credit goes to Ben (Bingxing) Wang on GitHub for reverse engineering most of the protocol. Also, as requested by Andy, I would like to clarify the use of __packed structs in this driver: - All the packed structs are aligned except for appletbdrm_msg_information. - We have to pack appletbdrm_msg_information since it is requirement of the protocol. - We compared binaries compiled by keeping the rest structs __packed and not __packed using bloat-o-meter, and __packed was not affecting code generation. - To maintain consistency, rest structs have been kept __packed. I would also like to point out that since the driver was reverse-engineered the actual data types of the protocol might be different, including, but not limited to, endianness.

There are conditions, albeit somewhat unlikely, under which right hand expressions, calculating the end of time period in functions like repaper_frame_fixed_repeat(), may overflow. For instance, if 'factor10x' in repaper_get_temperature() is high enough (170), as is 'epd->stage_time' in repaper_probe(), then the resulting value of 'end' will not fit in unsigned int expression. Mitigate this by casting 'epd->factored_stage_time' to wider type before any multiplication is done. Found by Linux Verification Center (linuxtesting.org) with static analysis tool SVACE.

2024-12-01Get rid of 'remove_new' relic from platform driver structLinus Torvalds
The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result.

2024-11-12gpu: drm: replace of_graph_get_next_endpoint()Kuninori Morimoto
From DT point of view, in general, drivers should be asking for a specific port number because their function is fixed in the binding. of_graph_get_next_endpoint() doesn't match to this concept. Simply replace - of_graph_get_next_endpoint(xxx, NULL); + of_graph_get_endpoint_by_regs(xxx, 0, -1); Link: https://lore.kernel.org/r/20240202174941.GA310089-robh@kernel.org Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Reviewed-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Link: https://patchwork.freedesktop.org/patch/msgid/87frob3neo.wl-kuninori.morimoto.gx@renesas.com
2024-10-28drm: handle HAS_IOPORT dependenciesNiklas Schnelle
In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at compile time. We thus need to add HAS_IOPORT as dependency for those drivers using them. In the bochs driver there is optional MMIO support detected at runtime, warn if this isn't taken when HAS_IOPORT is not defined. There is also a direct and hard coded use in cirrus.c which according to the comment is only necessary during resume. Let's just skip this as for example s390 which doesn't have I/O port support also doesen't support suspend/resume.
