-Dump kernel data structures in drgn
------------------------------------
-

-.. code-block:: python
-
- def align(x, a):
- """the alignment a should be a power of 2
- """
- mask = a - 1
- return (x+ mask) & ~mask
-

- return sizeof(Object(prog, struct_str, address=0x0))
-
- def netdev_priv(netdevice):
- NETDEV_ALIGN = 32
- return netdevice.value_() + align(struct_size("net_device"), NETDEV_ALIGN)
-
- name = 'xxx'
- qlge_device = None
- netdevices = prog['init_net'].dev_base_head.address_of_()
- for netdevice in list_for_each_entry("struct net_device", netdevices, "dev_list"):
- if netdevice.name.string_().decode('ascii') == name:
- print(netdevice.name)
-
- ql_adapter = Object(prog, "struct ql_adapter", address=netdev_priv(qlge_device))
-
-The struct ql_adapter will be printed in drgn as follows,
-

-coredump via devlink
---------------------
-
-
-And the coredump obtained via devlink in json format looks like,
-
-.. code:: shell
-
- $ devlink health dump show DEVICE reporter coredump -p -j
- {

- },
- ...
- "Sem Registers": {
- "segment": 50,

- }
- }
-
-When the module parameter qlge_force_coredump is set to be true, the MPI
-RISC reset before coredumping. So coredumping will much longer since
-devlink tool has to wait for 5 secs for the resetting to be
-finished.

-* commit 7c734359d350 ("qlge: Size RX buffers based on MTU.", v2.6.33-rc1)
- introduced dead code in the receive routines, which should be rewritten
- anyways by the admission of the author himself, see the comment above
- qlge_build_rx_skb(). That function is now used exclusively to handle packets
- that underwent header splitting but it still contains code to handle non
- split cases.
-* truesize accounting is incorrect (ex: a 9000B frame has skb->truesize 10280
- while containing two frags of order-1 allocations, ie. >16K)
-* while in that area, using two 8k buffers to store one 9k frame is a poor
- choice of buffer size.
-* in the "chain of large buffers" case, the driver uses an skb allocated with
- head room but only puts data in the frags.
-* rename "rx" queues to "completion" queues. Calling tx completion queues "rx
- queues" is confusing.
-* struct rx_ring is used for rx and tx completions, with some members relevant
- to one case only
-* the flow control implementation in firmware is buggy (sends a flood of pause
- frames, resets the link, device and driver buffer queues become
- desynchronized), disable it by default
-* the driver has a habit of using runtime checks where compile time checks are
- possible (ex. qlge_free_rx_buffers())
-* reorder struct members to avoid holes if it doesn't impact performance
-* use better-suited apis (ex. use pci_iomap() instead of ioremap())
-* remove duplicate and useless comments
-* fix weird line wrapping (all over, ex. the qlge_set_routing_reg() calls in
- qlge_set_multicast_list()).
-* remove useless casts (ex. memset((void *)mac_iocb_ptr, ...))
-* fix checkpatch issues
