2023-12-12PCI: layerscape: Add suspend/resume for ls1043aFrank Li
Add suspend/resume support for Layerscape LS1043a. In the suspend path, PME_Turn_Off message is sent to the endpoint to transition the link to L2/L3_Ready state. In this SoC, there is no way to check if the controller has received the PME_To_Ack from the endpoint or not. So to be on the safer side, the driver just waits for PCIE_PME_TO_L2_TIMEOUT_US before asserting the SoC specific PMXMTTURNOFF bit to complete the PME_Turn_Off handshake. Then the link would enter L2/L3 state depending on the VAUX supply. In the resume path, the link is brought back from L2 to L0 by doing a software reset.

2023-12-12PCI: layerscape: Add function pointer for exit_from_l2()Frank Li
Since different SoCs require different sequences for exiting L2, let's add a separate "exit_from_l2()" callback to handle SoC specific sequences. Change ls_pcie_exit_from_l2() return value from void to int in order to propagate errors. Return an error if the exit_from_l2() callback fails in the resume flow.

2023-12-05x86/pci: Comment pci_mmconfig_insert() obscure MCFG dependencyBjorn Helgaas
In pci_mmconfig_insert(), there's no reference to "addr" between locking pci_mmcfg_lock and testing "addr", so it *looks* like we should move the test before the lock. But 07f9b61c3915 ("x86/PCI: MMCONFIG: Check earlier for MMCONFIG region at address zero") did that, which broke things by returning -EINVAL when "addr" is zero instead of -EEXIST. So 07f9b61c3915 was reverted by 67d470e0e171 ("Revert "x86/PCI: MMCONFIG: Check earlier for MMCONFIG region at address zero""). Add a comment about this issue to prevent it from happening again.

2023-12-05x86/pci: Reword ECAM EfiMemoryMappedIO logging to avoid 'reserved'Bjorn Helgaas
fd3a8cff4d4a ("x86/pci: Treat EfiMemoryMappedIO as reservation of ECAM space") added the concept of using the EFI memory map to help decide whether ECAM space mentioned in the MCFG table is valid. Unfortunately it described that EfiMemoryMappedIO space as "reserved", but it is actually not *reserved* by the EFI memory map. EfiMemoryMappedIO only means the firmware requested that the OS map this space for use by firmware runtime services. Change the dmesg logging to describe it as simply "EfiMemoryMappedIO", not as "reserved as EfiMemoryMappedIO". A previous commit actually *does* reserve the space if ACPI PNP0C01/02 devices haven't done so: - PCI: ECAM at [mem 0xe0000000-0xefffffff] reserved as EfiMemoryMappedIO + PCI: ECAM at [mem 0xe0000000-0xefffffff] is EfiMemoryMappedIO; assuming valid PCI: ECAM [mem 0xe0000000-0xefffffff] reserved to work around lack of ACPI motherboard _CRS Link: https://lore.kernel.org/r/20231121183643.249006-3-helgaas@kernel.org Tested-by: Tomasz Pala <gotar@polanet.pl> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2023-12-05x86/pci: Reserve ECAM if BIOS didn't include it in PNP0C02 _CRSBjorn Helgaas
Tomasz, Sebastian, and some Proxmox users reported problems initializing ixgbe NICs. I think the problem is that ECAM space described in the ACPI MCFG table is not reserved via a PNP0C02 _CRS method as required by the PCI Firmware spec (r3.3, sec 4.1.2), but it *is* included in the PNP0A03 host bridge _CRS as part of the MMIO aperture. If we allocate space for a PCI BAR, we're likely to allocate it from that ECAM space, which obviously cannot work. This could happen for any device, but in the ixgbe case it happens because it's an SR-IOV device and the BIOS didn't allocate space for the VF BARs, so Linux reallocated the bridge window leading to ixgbe and put it on top of the ECAM space.

2023-11-22PCI: switchtec: Fix stdev_release() crash after surprise hot removeDaniel Stodden
A PCI device hot removal may occur while stdev->cdev is held open. The call to stdev_release() then happens during close or exit, at a point way past switchtec_pci_remove(). Otherwise the last ref would vanish with the trailing put_device(), just before return. At that later point in time, the devm cleanup has already removed the stdev->mmio_mrpc mapping. Also, the stdev->pdev reference was not a counted one. Therefore, in DMA mode, the iowrite32() in stdev_release() will cause a fatal page fault, and the subsequent dma_free_coherent(), if reached, would pass a stale &stdev->pdev->dev pointer. Fix by moving MRPC DMA shutdown into switchtec_pci_remove(), after stdev_kill(). Counting the stdev->pdev ref is now optional, but may prevent future accidents.

2023-11-20PCI: Avoid potential out-of-bounds read in pci_dev_for_each_resource()Andy Shevchenko
Coverity complains that pointer in the pci_dev_for_each_resource() may be wrong, i.e., might be used for the out-of-bounds read. There is no actual issue right now because we have another check afterwards and the out-of-bounds read is not being performed. In any case it's better code with this fixed, hence the proposed change. As Jonas pointed out "It probably makes the code slightly less performant as res will now be checked for being not NULL (which will always be true), but I doubt it will be significant (or in any hot paths)."

2023-11-20PCI: host-generic: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. pci_host_common_remove() returned zero unconditionally. With that converted to return void instead, the generic pci host driver can be switched to .remove_new() trivially.
