2016-12-12PCI: Enable access to non-standard VPD for Chelsio devices (cxgb3)Alexey Kardashevskiy
There is at least one Chelsio 10Gb card which uses VPD area to store some non-standard blocks (example below). However pci_vpd_size() returns the length of the first block only assuming that there can be only one VPD "End Tag". Since 4e1a635552d3 ("vfio/pci: Use kernel VPD access functions"), VFIO blocks access beyond that offset, which prevents the guest "cxgb3" driver from probing the device. The host system does not have this problem as its driver accesses the config space directly without pci_read_vpd(). Add a quirk to override the VPD size to a bigger value. The maximum size is taken from EEPROMSIZE in drivers/net/ethernet/chelsio/cxgb3/common.h. We do not read the tag as the cxgb3 driver does as the driver supports writing to EEPROM/VPD and when it writes, it only checks for 8192 bytes boundary. The quirk is registered for all devices supported by the cxgb3 driver. This adds a quirk to the PCI layer (not to the cxgb3 driver) as the cxgb3 driver itself accesses VPD directly and the problem only exists with the vfio-pci driver (when cxgb3 is not running on the host and may not be even loaded) which blocks accesses beyond the first block of VPD data. However vfio-pci itself does not have quirks mechanism so we add it to PCI. This is the controller: Ethernet controller [0200]: Chelsio Communications Inc T310 10GbE Single Port Adapter [1425:0030] This is what I parsed from its VPD: === b'\x82*\x0010 Gigabit Ethernet-SR PCI Express Adapter\x90J\x00EC\x07D76809 FN\x0746K' 0000 Large item 42 bytes; name 0x2 Identifier String b'10 Gigabit Ethernet-SR PCI Express Adapter' 002d Large item 74 bytes; name 0x10 #00 [EC] len=7: b'D76809 ' #0a [FN] len=7: b'46K7897' #14 [PN] len=7: b'46K7897' #1e [MN] len=4: b'1037' #25 [FC] len=4: b'5769' #2c [SN] len=12: b'YL102035603V' #3b [NA] len=12: b'00145E992ED1' 007a Small item 1 bytes; name 0xf End Tag 0c00 Large item 16 bytes; name 0x2 Identifier String b'S310E-SR-X ' 0c13 Large item 234 bytes; name 0x10 #00 [PN] len=16: b'TBD ' #13 [EC] len=16: b'110107730D2 ' #26 [SN] len=16: b'97YL102035603V ' #39 [NA] len=12: b'00145E992ED1' #48 [V0] len=6: b'175000' #51 [V1] len=6: b'266666' #5a [V2] len=6: b'266666' #63 [V3] len=6: b'2000 ' #6c [V4] len=2: b'1 ' #71 [V5] len=6: b'c2 ' #7a [V6] len=6: b'0 ' #83 [V7] len=2: b'1 ' #88 [V8] len=2: b'0 ' #8d [V9] len=2: b'0 ' #92 [VA] len=2: b'0 ' #97 [RV] len=80: b's\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00'... 0d00 Large item 252 bytes; name 0x11 #00 [VC] len=16: b'122310_1222 dp ' #13 [VD] len=16: b'610-0001-00 H1\x00\x00' #26 [VE] len=16: b'122310_1353 fp ' #39 [VF] len=16: b'610-0001-00 H1\x00\x00' #4c [RW] len=173: b'\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00'... 0dff Small item 0 bytes; name 0xf End Tag 10f3 Large item 13315 bytes; name 0x62 !!! unknown item name 98: b'\xd0\x03\x00@`\x0c\x08\x00\x00\x00\x00\x00\x00\x00\x00\x00' === Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

We already log a "Signaling PME" whenever the PME service driver claims a Root Port. In fact, we also log the same message for every device in the hierarchy below the Root Port.

2016-12-12mmc: block: Move files to coreUlf Hansson
Once upon a time it made sense to keep the mmc block device driver and its related code, in its own directory called card. Over time, more an more functions/structures have become shared through generic mmc header files, between the core and the card directory. In other words, the relationship between them has become closer. By sharing functions/structures via generic header files, it becomes easy for outside users to abuse them. In a way to avoid that from happen, let's move the files from card directory into the core directory, as it enables us to move definitions of functions/structures into mmc core specific header files. Note, this is only the first step in providing a cleaner mmc interface for outside users. Following changes will do the actual cleanup, as that is not part of this change.
