cxgb4: Fix to dump devlog, even if FW is crashed

2015-04-01T18:47:20+00:00

Add new Common Code routines to retrieve Firmware Device Log
parameters from PCIE_FW_PF[7]. The firmware initializes its Device Log very
early on and stores the parameters for its location/size in that register.
Using the parameters from the register allows us to access the Firmware
Device Log even when the firmware crashes very early on or we're not
attached to the firmware

cxgb4: Disable interrupts and napi before unregistering netdev

2015-03-29T19:24:43+00:00

Disable interrupts and quiesce rx before unregistering net device to avoid crash
while unloading driver when traffic is flowing through.

cxgb4: Allocate dynamic mem. for egress and ingress queue maps

2015-03-29T19:24:42+00:00

QIDs (egress/ingress) from firmware in FW_*_CMD.alloc command
can be anywhere in the range from EQ(IQFLINT)_START to EQ(IQFLINT)_END.
For eg, in the first load eqid can be from 100 to 300.
In the next load it can be from 301 to 500 (assume eq_start is 100 and eq_end is
1000).

The driver was assuming them to always start from EQ(IQFLINT)_START till
MAX_EGRQ(INGQ). This was causing stack overflow and subsequent crash.

Fixed it by dynamically allocating memory (of qsize (x_END - x_START + 1)) for
these structures.

cxgb4: Fix PCI-E Memory window interface for big-endian systems

2015-02-27T20:53:43+00:00

When doing reads and writes to adapter memory via the PCI-E Memory Window
interface, data gets swizzled on 4-byte boundaries on Big-Endian systems
because we need to account for the register read/write interface which
incorporates a swizzle onto the Little-Endian PCI-E Bus.

Merge branch 'debugfs_automount' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

2015-02-17T23:18:19+00:00

Pull debugfs patches from Al Viro:
 "debugfs patches, mostly to make it possible for something like tracefs
  to be transparently automounted on given directory in debugfs.

  New primitive in there is debugfs_create_automount(name, parent, func,
  arg), which creates a directory and makes its ->d_automount() return
  func(arg).  Another missing primitive was debugfs_create_file_size() -
  open-coded in quite a few places.  Dave's patch adds it and converts
  the open-code instances to calling it"

* 'debugfs_automount' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  debugfs: Provide a file creation function that also takes an initial size
  new primitive: debugfs_create_automount()
  debugfs: split end_creating() into success and failure cases
  debugfs: take mode-dependent parts of debugfs_get_inode() into callers
  fold debugfs_mknod() into callers
  fold debugfs_create() into caller
  fold debugfs_mkdir() into caller
  debugfs_mknod(): get rid useless arguments
  fold debugfs_link() into caller
  debugfs: kill __create_file()
  debugfs: split the beginning and the end of __create_file() off
  debugfs_{mkdir,create,link}(): get rid of redundant argument
