ae92db9ed6 NTB: MFV c336acd3: memcpy lockup workaround
The system will appear to lockup for long periods of time due to the NTB
driver spending too much time in memcpy.  Avoid this by reducing the
number of packets that can be serviced on a given interrupt.

7ee9e4bc6e NTB: MFV c9d534c8: Correctly handle receive buffers of the minimal size
The ring logic of the NTB receive buffer/transmit memory window requires
there to be at least 2 payload sized allotments.  For the minimal size
case, split the buffer into two and set the transport_mtu to the
appropriate size.

a30525bf65 NTB: MFV 90f9e934: reset tx_index on link toggle
If the NTB link toggles, the driver could stop receiving due to the
tx_index not being set to 0 on the transmitting size on a link-up event.
This is due to the driver expecting the incoming data to start at the
beginning of the receive buffer and not at a random place.

0125f2c1af NTB: MFV b77b2637: Link toggle memory leak
Each link-up will allocate a new NTB receive buffer when the NTB
properties are negotiated with the remote system.  These allocations did
not check for existing buffers and thus did not free them.  Now, the
driver will check for an existing buffer and free it if not of the
correct size, before trying to alloc a new one.

92bbfa507c NTB: MFV 113fc505: Handle 64bit BAR sizes
64bit BAR sizes are permissible with an NTB device.  To support them
various modifications and clean-ups were required, most significantly
using 2 32bit scratch pad registers for each BAR.

Also, modify the driver to allow more than 2 Memory Windows.

dfff069863 Simplify netbsd-tests.test.mk
- projects/bmake and subsequent commits provide SRCTOP; there's no need to
  manually specify it now.
- Compute a sane default for OBJTOP based on .OBJDIR and RELDIR. Manually
  specifying this is probably no longer needed, but it persists just in case
  (supporting commits will need to be made to move it out of some of the meta
  .mk files).
- Compute a sane default for TESTSRC. Error out if the path cannot be found.

92001b9497 Change the default setting of kern.ipc.shm_allow_removed from 0 to 1.
This removes the need for manually changing this flag for Google Chrome
users. It also improves compatibility with Linux applications running under
Linuxulator compatibility layer, and possibly also helps in porting software
from Linux.

Generally speaking, the flag allows applications to create the shared memory
segment, attach it, remove it, and then continue to use it and to reattach it
later. This means that the kernel will automatically "clean up" after the
application exits.

It could be argued that it's against POSIX. However, SUSv3 says this
about IPC_RMID: "Remove the shared memory identifier specified by shmid from
the system and destroy the shared memory segment and shmid_ds data structure
associated with it." From my reading, we break it in any case by deferring
removal of the segment until it's detached; we won't break it any more
by also deferring removal of the identifier.

This is the behaviour exhibited by Linux since... probably always, and
also by OpenBSD since the following commit:

revision 1.54
date: 2011/10/27 07:56:28; author: robert; state: Exp; lines: +3 -8;
Allow segments to be used even after they were marked for deletion with
the IPC_RMID flag.
This is permitted as an extension beyond the standards and this is similar
to what other operating systems like linux do.

27b3a39a8f Update the AP135 reference design flash layout to be more useful.
* Shuffle the kernel to be at the beginning
* Give the kernel 2mb, the rootfs 6mb, and 'mib0' the rest
* put the cfg parition just before the ART calibration data for the
  wifi part in the SoC
* .. and make sure ART points to the right 64k region.

I've updated the freebsd-wifi-build wiki the instructions on using this.

If someone has an AP135 with 8MB SPI flash then this won't work; everything
minus the big mib0 partition is just a bit over 8MB.  Come see me if this
ever happens (you'll likely just have to shrink the rootfs and the kernel
a little in order to make it fit.)

Tested:

* AP135 reference board.

dc809fc15f Flip on fast frames support for AR5416 and AR9300 series NICs.
This was off because the net80211 aggregation code was using the same
state pointers for both fast frames and ampdu tx support which led to some
pretty unfortunate panic-y behaviour.

Now that net80211 doesn't panic, let's flip this back on.

It doesn't (yet) do the horrific sounding thing of A-MPDU aggregates
of fast frames; that'll come next.  It's a pre-requisite to supporting
AMSDU + AMPDU anyway, which actually speeds things up quite considerably
(think packing lots of little ACK frames into a single AMSDU.)

Tested:

* QCA955x SoC, AP mode
* AR5416, STA mode
* AR9170, STA mode (with local fast frame patches)

4006520bea Fix more cases of iicbus-layer functions that must return IIC_Exxxx values. 2015-10-10 00:12:03 +00:00
Ian Lepore
48e5b4261a Return only IIC_Exxxx status values from iicbus-layer functions. Most of
these functions are thin wrappers around calling the hardware-layer driver,
but some of them do sanity checks and return an error.  Since the hardware
layer can only return IIC_Exxxxx status values, the iicbus helper functions
must also adhere to that, so that drivers at higher layers can assume that
any non-zero status value is an IIC_Exxxx value that provides details about
what happened at the hardware layer (sometimes those details are important
for certain slave drivers).

df38292a85 Add iic2errno(), a helper function to translate IIC_Exxxxx status values to
errno values that are at least vaguely equivelent.  Also add a new status
value, IIC_ERESOURCE, to indicate a failure to acquire memory or other
required resources to complete a transaction.

The IIC_Exxxxxx values are supposed to communicate low-level details of the
i2c transaction status between the lowest-layer hardware driver and
higher-layer bus protocol and device drivers for slave devices on the bus.
Most of those slave drivers just return all status values from the lower
layers directly to their callers, resulting in crazy error reporting from a
user's point of view (things like timeouts being reported as "no such
process").  Now there's a helper function to make it easier to start
cleaning up all those drivers.

d1e99670ae Use IIC_EBUSBSY and IIC_BUSERR status values consistantly across all drivers.
Make it clearer what each one means in the comments that define them.

IIC_BUSBSY was used in many places to mean two different things, either
"someone else has reserved the bus so you have to wait until they're done"
or "the signal level on the bus was not in the state I expected before/after
issuing some command".

Now IIC_BUSERR is used consistantly to refer to protocol/signaling errors,
and IIC_BUSBSY refers to ownership/reservation of the bus.

d2c05e201f Mostly rewrite the imx i2c driver. This started out as an attempt to fix
one specific problem: the driver didn't check for ACK/NAK after writing a
slave address byte to the bus, and some slaves signal that they are busy
(such as when completing an internal write to flash memory) by sending a
NAK in response to being addressed.

While working on that problem I discovered that the driver's handling of
error conditions in general didn't match the state transition diagram in
the reference manual, and making that right resulted in a lot of code
reorganization.

Along the way various other changes also happened...

 - Remove a mutex that wasn't protecting anything.
 - Remove some mystery DELAY()s, document the few that remain.
 - Use pause_sbt(9) to yield the processor for the bulk of the time it
   takes to transfer each byte rather than busy-polling the whole time.
 - Disable the controller when no transfers are in progress; since we
   don't operate in slave mode, there's no reason to run the hardware.
 - Remove a bunch of unecessary code from probe().
