ieee1394: eth1394: don't autoload by hotplug when ohci1394 starts

Until now, ieee1394 put an IP-over-1394 capability entry into each new
host's config ROM.  As soon as the controller was initialized --- i.e.
right after modprobe ohci1394 --- this entry triggered a hotplug event
which typically caused auto-loading of eth1394.

This irritated or annoyed many users and distributors.  Of course they
could blacklist eth1394, but then ieee1394 wrongly advertized IP-over-
1394 capability to the FireWire bus.

Therefore
  - remove the offending kernel config option
    IEEE1394_CONFIG_ROM_IP1394,
  - let eth1394 add the ROM entry by itself, i.e. only after eth1394 was
    loaded.

This fixes http://bugzilla.kernel.org/show_bug.cgi?id=7793 .

To emulate the behaviour of older kernels, simply add the following to
to /etc/modprobe.conf:

install ohci1394 /sbin/modprobe eth1394; \
                 /sbin/modprobe --ignore-install ohci1394

Note, autoloading of eth1394 when an _external_ IP-over-1394 capable
device is discovered is _not_ affected by this patch.

Stefan Richter [Sun, 11 Mar 2007 21:51:24 +0000]
ieee1394: replace vmalloc by kmalloc in csr1212

The biggest chunk ever allocated by CSR1212_MALLOC is 1024 Bytes +
sizeof(struct csr1212_csr_rom_cache) big.  Most of the time much
smaller data structures are allocated.  Therefore vmalloc is a waste.

The one exception is csr1212_append_new_cache() which is called to
append a chunk of CSR1212_EXTENDED_ROM_SIZE + sizeof(struct
csr1212_csr_rom_cache) if the currently allocated ROM cache is too
small.  CSR1212_EXTENDED_ROM_SIZE is generously defined as 256 kBytes.
In SVN commit 1220, Steve Kinneberg lowered this to 2 kBytes in the
config_rom_2.4 branch.  This same commit also switched CSR1212_MALLOC
from kmalloc to vmalloc in the SVN trunk branch:

I am now setting CSR1212_EXTENDED_ROM_SIZE to 2 kB minus the overhead of
struct csr1212_csr_rom_cache.  Note, this code path is not used by the
in-kernel drivers though.  raw1394 could trigger it, but the respective
libraw1394 functions don't exist yet.

Furthermore, userspace programs can replace the entire local ROM via
raw1394.  If kmalloc does not fulfill their needs --- well, tough luck.
I decree that nobody needs such huge extended ROMs.  (Extended ROMs are
defined by IEEE 1212 clause 7.7.18.  The spec does not impose
practically relevant restrictions on the size of extended ROM chunks.)

Another potentially demanding use of CSR1212_MALLOC is if external
FireWire devices come with Extended ROM entries.  If they are too big
for kmalloc (or have been too big for vmalloc) we just fail to read
their ROM.  This is quite unlikely though, to my knowledge.

ieee1394: sbp2: optimize DMA direction of s/g tables

Unlike the name suggests, "cmd->scatter_gather_element" holds only the
s/g table, not the actual s/g elements.  Since the table is only read
but never written by the device, DMA_BIDIRECTIONAL can be replaced by
DMA_TO_DEVICE which may be cheaper on some architectures.

13 years agoieee1394: sbp2: remove unnecessary alignments of struct members
Stefan Richter [Sun, 4 Feb 2007 12:04:32 +0000]
ieee1394: sbp2: remove unnecessary alignments of struct members

The members "dma_addr_t command_orb_dma" and "dma_addr_t sge_dma" of
sbp2.h::sbp2_command_info do not have to be aligned themselves --- only
the memory which they point to has to be.

The member "struct sbp2_command_orb command_orb" has to be aligned on
4 bytes boundary which is guaranteed because it contains u32 members.

The member "struct sbp2_unrestricted_page_table scatter_gather_element",
i.e. the SBP-2 s/g table, has to be aligned on 8 bytes boundary
according to the SBP-2 spec.  This is not a requirement for FireWire
controllers but could be expected by SBP-2 targets.

I see no need to align the members command_orb and
scatter_gather_element on CPU cacheline boundaries.  It could have
performance benefits, but on the other hand sbp2 has a somewhat wasteful
allocation scheme which should be optimized first before further tweaks
like cacheline alignments.  (E.g. don't always allocate SG_ALL s/g table
elements.)

Note, before as well as after the patch, the code relies on the
assumption that memory alignment in the virtual address space is
preserved in the physical address space after DMA mapping.

13 years agosis900: Allocate rx replacement buffer before rx operation
Neil Horman [Thu, 26 Apr 2007 17:47:36 +0000]
sis900: Allocate rx replacement buffer before rx operation

Just found a hole in my last patch.  It was reported to me that shortly after we
integrated this patch.  The report was of an oops that took place inside of
netif_rx when using the sis900 driver.  Looking at my origional patch I noted
that there was a spot between the new skb_alloc and the refill_rx_ring label
where skb got reassigned to the pointer currently held in the rx_ring for the
purposes of receiveing the frame.  The result of this is however that the buffer
that gets passed to netif_rx (if it is called), then gets placed right back into
the rx_ring.  So if you receive frames fast enough the skb being processed by
the network stack can get corrupted.  The reporter is testing out the fix I've
written for this below (I'm not near my hardware at the moment to test myself),
but I wanted to post it for review ASAP.  I'll post test results when I hear
them, but I think this is a pretty straightforward fix.  It just uses a separate
pointer to do the rx operation, so that we don't improperly reassign the pointer
that we use to refill the rx ring.

Eberhard Fahle [Thu, 5 Apr 2007 09:13:21 +0000]
USB: iowarrior.c: timeouts too small in usb_control_msg calls

The driver uses usb_control_msg() for exchanging data with the device.
When the driver lived freeley _outside_ the kernel tree (pre 2.6.21) the
timeouts for these calls where set to 5*HZ for reading, 1HZ for writing.
(These timeouts seemed to work fine for all users of the driver, at
least nobody complained in the last 2 years.

The current code (2.6.21-rc5) removed the 'HZ' from the timeouts and
left the driver with 5 jiffies for reading and 1 jiffy for writing. My
new machine is fast, but not that fast.

The patch also removes a useless debug statement, which was left over
from testing a broken firmware version

usbmon: bus zero

Add the "bus zero" feature to the usbmon. If a user process specifies bus
with number zero, it receives events from all buses. This is useful when
we wish to see initial enumeration when a bus is created, typically after
a modprobe. Until now, an application had to loop until a new bus could
be open, then start capturing on it. This procedure was cumbersome and
could lose initial events. Also, often it's too bothersome to find exactly
to which bus a specific device is attached.

Paolo Albeni provided the original concept implementation. I added the
handling of "bus->monitored" flag and generally fixed it up.

USB: add "last_busy" field for use in autosuspend

This patch (as877) adds a "last_busy" field to struct usb_device, for
use by the autosuspend framework.  Now if an autosuspend call comes at
a time when the device isn't busy but hasn't yet been idle for long
enough, the timer can be set to exactly the desired value.  And we
will be ready to handle things like HID drivers, which can't maintain
a useful usage count and must rely on the time-of-last-use to decide
when to autosuspend.

The patch also makes some related minor improvements:

Move the calls to the autosuspend condition-checking routine
into usb_suspend_both(), which is the only place where it
really matters.

If the autosuspend timer is already running, don't stop
and restart it.

Replace immediate returns with gotos so that the optional
debugging ouput won't be bypassed.

If autoresume is disabled but the device is already awake,
don't return an error for an autoresume call.

Don't try to autoresume a device if it isn't suspended.
(Yes, this undercuts the previous change -- so sue me.)

Don't duplicate existing code in the autosuspend work routine.

Fix the kerneldoc in usb_autopm_put_interface(): If an
autoresume call fails, the usage counter is left unchanged.
