pci_dev_resource_x is a superset of pci_dev_resource and they're just temp structs used during resource reallocation. pci_dev_resource usage is quite limted. So just use pci_dev_resource_x, and rename it as new pci_dev_resource. -v2: According to Linus, Separate free_list change to another patch Suggested-by:

On a system with devices that support SRIOV connected to a pcie switch to pcie root port: +-[0000:80]-+-00.0-[81-8f]-- | +-01.0-[90-9f]-- | +-02.0-[a0-af]----00.0-[a1-a3]--+-02.0-[a2]--+-00.0 Oracle Corporation Device 207a | | \-03.0-[a3]--+-00.0 Oracle Corporation Device 207a | +-02.2-[b0-bf]----00.0-[b1-b3]--+-02.0-[b2]--+-00.0 Oracle Corporation Device 207a | | \-03.0-[b3]--+-00.0 Oracle Corporation Device 207a When the BIOS does not assign resources for SRIOV BARs, kernel pci reallocation only goes up one bridge and then gives up, failing to to get resources for all sSRIOV BARs, even though the range is large enough in the peer root bus. Specifically, only the bridge at the a1:02.0 level has its resources cleared and reallocated. The kernel does not go up to clear the bridge at the 80:02.0 level. To make it go to upper levels, during retry, we need to treat "good to have" resources as "must have". Only on the last try will we treat good to have resources as optional. At that time, parent bridge resources will already have been released so we'll have a chance to get everything assigned with must_have plus good_to_have for all child devices. Signed-off-by:

This allows us to allocate resources to hotplug bridges during remove/rescan. We need to move the function to setup-bus.c so it can use __pci_bus_size_bridges and __pci_bus_assign_resources directly to take the add_list resource tracking list. Signed-off-by:

Current rescan will not touch bridge MMIO and IO. Try to reuse pci_assign_unassigned_bridge_resources(bridge) to update bridge resources, if child devices need more resources. Only do that for bridges whose children are all removed already; i.e. don't release resources that could already be in use by drivers on child devices. Signed-off-by:

We found reassignment can not find a range for one resource, even if the total available range is large enough. bridge b1:02.0 will need 2M+3M bridge b1:03.0 will need 2M+3M so bridge b0:00.0 will get assigned: 4M : [f8000000-f83fffff] later is reassigned to 10M : [f8000000-f9ffffff] b1:02.0 is assigned to 2M : [f8000000-f81fffff] b1:03.0 is assigned to 2M : [f8200000-f83fffff] After that b1:03.0 get chance to be reassigned to [f8200000-f86fffff], but b1:02.0 will not have chance to expand, because b1:03.0 is using in middle one.

During debug of one SRIOV enabled hotplug device, we found found that add_size is not passed properly.

So just pass add_size with size1 to calculate_memsize(). With this change, we should have chance to remove extra addon in pci_reassign_resource. Signed-off-by: -

We use the __pci_reset_function_locked to perform the action. Also on attaching ("bind") and detaching ("unbind") we save and restore the configuration states.

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.

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. Signed-off-by:

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.

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.

Both the suspend and resume functions incorrectly set psbfb = to_psb_fb(NULL) outside of the loop over all of the framebuffers. Fix this by moving the assignment of psbfb inside the loop and removing the initialisation of fb. Signed-off-by:

this patch separates fimd specific power on/off function from pm function and the pm interfaces will call that function for power on or off. and also removes unnecessary codes of resume function. Signed-off-by:

DRM_EXYNOS_HDMI driver and VIDEO_SAMSUNG_S5P_TV driver should be not enabled at once because they use same HW blocks. So dependency for DRM_EXYNOS_HDMI is fixed to check VIDEO_SAMSUNG_S5P_TV=n. Signed-off-by:

In error cleanup of agp_backend_initialize() and in agp_backend_cleanup(), agp_destroy_page() is passed virtual address of the scratch page. This leads to a kernel warning if the initialization fails (or upon regular cleanup) as pointer to struct page should be passed instead. Signed-off-by:
