find_child_device() on ACPI node works only once

by Timur Tabi

I need help getting my ACPI table parsing code to work correctly. My driver fails to find the child device in a node when the driver is unloaded and reloaded. I suspect that I'm not freeing a resource correctly. Here is my ACPI table (trimmed): Device (MAC0) { Name (_HID, "QCOM8070") Name (_UID, 0) Method (_CRS, 0x0, Serialized) { Name (RBUF, ResourceTemplate() { ... Return (RBUF) } } Device (IPHY) { Name (_HID, "QCOM8071") Method (_CRS, 0x0, Serialized) { Name (RBUF, ResourceTemplate () { ... Return (RBUF) } } So QCOM8071 is a child device for QCOM8070. The driver probes on QCOM8070 and then manually instantiates QCOM8071. static const struct acpi_device_id emac_acpi_match[] = { { .id = "QCOM8070", }, {} }; MODULE_DEVICE_TABLE(acpi, emac_acpi_match); static struct platform_driver emac_platform_driver = { .probe = emac_probe, .remove = emac_remove, .driver = { .name = "qcom-emac", .acpi_match_table = ACPI_PTR(emac_acpi_match), }, }; In emac_probe, I do this: struct device *dev; dev = device_find_child(&pdev->dev, NULL, emac_sgmii_acpi_match); adpt->sgmii_pdev = to_platform_device(dev); And here's emac_sgmii_acpi_match: > static int emac_sgmii_acpi_match(struct device *dev, void *data) > { > static const struct acpi_device_id match_table[] = { > { > .id = "QCOM8071", > }, > {} > }; > const struct acpi_device_id *id = acpi_match_device(match_table, dev); > > return !!id; > } When my driver exits, I call platform_device_unregister(adpt->sgmii_pdev); So here's the problem: the second time my driver is loaded, emac_sgmii_acpi_match() always returns false. The QCOM8071 child node no longer exists. It's apparently hidden in some way. I've been trying for several days to debug this, and I'm at my wits' end. I'm assuming that I'm not freeing the resource properly, but other than calling platform_device_unregister(), what else should I do? -- Qualcomm Datacenter Technologies, Inc. as an affiliate of Qualcomm Technologies, Inc.

[PATCH v13 0/8] acpi, clocksource: add GTDT driver and GTDT support in arm_arch_timer

by fu.wei＠linaro.org

From: Fu Wei <fu.wei(a)linaro.org> This patchset: (1)Preparation for adding GTDT support in arm_arch_timer: 1. Move some enums and marcos to header file; 2. Add a new enum for spi type; 3. Improve printk relevant code. (2)Introduce ACPI GTDT parser: drivers/acpi/arm64/acpi_gtdt.c Parse all kinds of timer in GTDT table of ACPI:arch timer, memory-mapped timer and SBSA Generic Watchdog timer. This driver can help to simplify all the relevant timer drivers, and separate all the ACPI GTDT knowledge from them. (3)Simplify ACPI code for arm_arch_timer (4)Add GTDT support for ARM memory-mapped timer, also refactor original memory-mapped timer dt support for reusing some common code.

[RFC PATCH V5 0/5] ECAM quirks handling for ARM64 platforms

by Tomasz Nowicki

Quirk handling relies on an idea of matching MCFG OEM ID, TABLE ID and revision (the ones from standard header of MCFG table). Static array is used to keep quirk entries. Each entry consists of mentioned MCFG IDs along with custom pci_ops structure and initialization call. As an example, the last patch presents quirk handling mechanism usage for ThunderX PEM driver. v4 -> v5 - rebase against v4.8-rc1 - rework to exact MCFG OEM ID, TABLE ID, rev match - use memcmp instead of strncmp - no substring match - fix typos and dmesg message Tomasz Nowicki (5): PCI: Embed pci_ecam_ops in pci_config_window structure PCI/ACPI: Move ACPI ECAM mapping to generic MCFG driver PCI: Check platform specific ECAM quirks ARM64/PCI: Start using quirks handling for ACPI based PCI host controller PCI: thunder-pem: Support quirky configuration space access for ACPI based PCI host controller arch/arm64/kernel/pci.c | 42 +---------------- drivers/acpi/pci_mcfg.c | 40 ++++++++++++++++ drivers/pci/ecam.c | 6 +-- drivers/pci/host/Makefile | 1 + drivers/pci/host/mcfg-quirks.c | 93 ++++++++++++++++++++++++++++++++++++ drivers/pci/host/mcfg-quirks.h | 24 ++++++++++ drivers/pci/host/pci-thunder-pem.c | 96 ++++++++++++++++++++++++++++++++------ include/linux/pci-acpi.h | 5 ++ include/linux/pci-ecam.h | 2 +- 9 files changed, 252 insertions(+), 57 deletions(-) create mode 100644 drivers/pci/host/mcfg-quirks.c create mode 100644 drivers/pci/host/mcfg-quirks.h -- 1.9.1
