The use case of this is when a driver wants to call FLR when a device is attached to it using the SysFS "bind" or "unbind" functionality. The call chain when a user does "bind" looks as so: echo "0000:01.07.0" > /sys/bus/pci/drivers/XXXX/bind and ends up calling: driver_bind: device_lock(dev); <=== TAKES LOCK XXXX_probe: .. pci_enable_device() ...__pci_reset_function(), which calls pci_dev_reset(dev, 0): if (!0) { device_lock(dev) <==== DEADLOCK The __pci_reset_function_locked function allows the the drivers 'probe' function to call the "pci_reset_function" while still holding the driver mutex lock.

Add missing iounmap in error handling code, in a case where the function already preforms iounmap on some other execution path. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression e; statement S,S1; int ret; @@ e = \(ioremap\|ioremap_nocache\)(...) ... when != iounmap(e) if (<+...e...+>) S ... when any when != iounmap(e) *if (...) { ... when != iounmap(e) return ...; } ... when any iounmap(e); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

This patch converts the underlying maintenance aspects of FW-assigned BIOS BAR values from a statically allocated array within struct pci_dev to a list of temporary, stand alone, entries. Signed-off-by: Myron Stowe <myron.stowe@redhat.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

Myron Stowe authored
Commit 58c84eda introduced functionality to try and reinstate the original BIOS BAR addresses of a PCI device when normal resource assignment attempts fail. To keep track of the BIOS BAR addresses, struct pci_dev was augmented with an array to hold the BAR addresses of the PCI device: 'resource_size_t fw_addr[DEVICE_COUNT_RESOURCE]'. The reinstatement of BAR addresses is an uncommon event leaving the 'fw_addr' array unused under normal circumstances. This functionality is also currently architecture specific with an implementation limited to x86. As the use of struct pci_dev is so prevalent, having the 'fw_addr' array residing within such seems somewhat wasteful. This patch introduces a stand alone data structure and interfacing routines for maintaining a list of FW-assigned BIOS BAR value entries.

Myron Stowe authored
pci_revert_fw_address() is used to reinstate a PCI device's original FW-assigned BIOS BAR value(s) if normal resource assignment fails. When attempting to reinstate an address, the point within the resource tree from which to attempt the new resource request should be the parent resource corresponding to the device, not the base of the resource tree (ioport_resource or iomem_resource). For PCI devices this would typically be the resource corresponding to the upstream PCI host bridge or P2P bridge aperture. This patch sets the point within the resource tree to attempt a new resource assignment request to the PCI device's parent resource and only if that fails does it fall back to the base ioport_resource or iomem_resource.

During test busn_res allocation with cardbus, found pci card removal is not working anymore, and it turns out it is broken by: |commit 79cc9601 |Date: Tue Nov 22 21:06:53 2011 -0800 | | PCI: Only call pci_stop_bus_device() one time for child devices at remove The above changed the behavior of pci_remove_behind_bridge that yenta_cardbus depended on. So restore the old behavoir of pci_remove_behind_bridge (which requires stopping and removing of all devices) by: 1. rename pci_remove_behind_bridge to __pci_remove_behind_bridge, and let __pci_remove_bus_device() call it instead. 2. add pci_stop_behind_bridge that will stop devices behind a bridge 3. add back pci_remove_behind_bridge that will stop and remove devices under bridge. -v2: update commit description a little bit.

For an SRIOV device, PCI_SRIOV_SYS_PGSIZE should be set before the PCI_SRIOV_BAR are queried. The sys pagesize defaults to 4k, so this change is required on powerpc box with 64k base page size. This is a regression caused due to moving SRIOV init to sriov_enable(). | commit afd24ece | Author: Ram Pai <linuxram@us.ibm.com> | PCI: delay configuration of SRIOV capability | The SRIOV capability, namely page size and total_vfs of a device are | configured during enumeration phase of the device.

Fixes PCI device detection on IBM xSeries IBM 3850 M2 / x3950 M2 when using ACPI resources (_CRS). This is default, a manual workaround (without this patch) would be pci=nocrs boot param. V2: Add dev_warn if the workaround is hit.

We've decided to provide CPU family specific container files (starting with CPU family 15h). E.g. for family 15h we have to load microcode_amd_fam15h.bin instead of microcode_amd.bin Rationale is that starting with family 15h patch size is larger than 2KB which was hard coded as maximum patch size in various microcode loaders (not just Linux). Container files which include patches larger than 2KB cause different kinds of trouble with such old patch loaders. Thus we have to ensure that the default container file provides only patches with size less than 2KB.
