Staging driver updates for 6.7-rc1

Browse Source 
Here is the big set of staging driver updates for 6.7-rc1.  A bit bigger
 than 6.6 this time around, as it coincided with the Outreachy and
 mentorship application process, so we got a bunch of new developers
 sending in their first changes, which is nice to see.
 
 Also in here is a removal of the qlge ethernet driver, and the rtl8192u
 wireless driver.  Both of these were very old and no one was maintaining
 them, the wireless driver removal was due to no one using it anymore,
 and no hardware to be found, and is part of a larger effort to remove
 unused and old wifi drivers from the system.
 
 The qlge ethernet driver did have one user pop up after it was dropped,
 and we are working with the network mainainers to figure out what tree
 it will come back in from and who will be responsible for it, and if it
 really is being used or not.  Odds are it will show up in a network
 subsystem pull request after -rc1 is out, but we aren't sure yet.
 
 Other smaller changes in here are:
   - Lots of vc04_services work by Umang to clean up the mess created by
     the rpi developers long ago, bringing it almost into good enough
     shape to get out of staging, hopefully next major release, it's
     getting close.
   - rtl8192e variable cleanups and removal of unused code and structures
   - vme_user coding style cleanups
   - other small coding style cleanups to lots of the staging drivers
   - octeon typedef removals, and then last-minute revert when it was
     found to break the build in some configurations (it's a hard driver
     to build properly, none of the normal automated testing catches it.)
 
 All of these have been in linux-next for a while with no reported
 issues.

This driver use drgn and devlink for debugging.
Dump kernel data structures in drgn
-----------------------------------
To dump kernel data structures, the following Python script can be used
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
def struct_size(struct_type):
struct_str = "struct {}".format(struct_type)
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,
>>> ql_adapter
(struct ql_adapter){
.ricb = (struct ricb){
.base_cq = (u8)0,
.flags = (u8)120,

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
{
"Core Registers": {
"segment": 1,
"values": [ 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 ]
},
"Test Logic Regs": {
"segment": 2,
"values": [ 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 ]
},
"RMII Registers": {
"segment": 3,
"values": [ 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 ]
},
...
"Sem Registers": {
"segment": 50,
"values": [ 0,0,0,0 ]
}
}
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
ql_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
* some structures are initialized redundantly (ex. memset 0 after
alloc_etherdev())
* the driver has a habit of using runtime checks where compile time checks are
possible (ex. ql_free_rx_buffers(), ql_alloc_rx_buffers())
* reorder struct members to avoid holes if it doesn't impact performance
* avoid legacy/deprecated apis (ex. replace pci_dma_*, replace pci_enable_msi,
use pci_iomap)
* some "while" loops could be rewritten with simple "for", ex.
ql_wait_reg_rdy(), ql_start_rx_ring())
* remove duplicate and useless comments
* fix weird line wrapping (all over, ex. the ql_set_routing_reg() calls in
qlge_set_multicast_list()).
* fix weird indentation (all over, ex. the for loops in qlge_get_stats())
* fix checkpatch issues

To-do list:
* Correct the coding style according to Linux guidelines; please read the document
at https://www.kernel.org/doc/html/latest/process/coding-style.html.
* Remove unnecessary debugging/printing macros; for those that are still needed
use the proper kernel API (pr_debug(), dev_dbg(), netdev_dbg()).
* Remove dead code such as unusued functions, variables, fields, etc..
* Use in-kernel API and remove unnecessary wrappers where possible.
* Fix bugs due to code that sleeps in atomic context.
* Remove the HAL layer and migrate its functionality into the relevant parts of
the driver.
* Switch to use LIB80211.
* Switch to use MAC80211.
* Switch to use CFG80211.
* Improve the error handling of various functions, particularly those that use
existing kernel APIs.
