* NTB: MFV c336acd3: memcpy lockup workaroundConrad Meyer2015-10-111-2/+3
| | | | | | | | | | | | | 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.

* NTB: MFV c9d534c8: Correctly handle receive buffers of the minimal sizeConrad Meyer2015-10-111-3/+5
| | | | | | | | | | | | | | 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.

* NTB: MFV 90f9e934: reset tx_index on link toggleConrad Meyer2015-10-111-2/+1
| | | | | | | | | | | | | | 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.

* NTB: MFV b77b2637: Link toggle memory leakConrad Meyer2015-10-111-0/+8
| | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | 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.

* Change the default setting of kern.ipc.shm_allow_removed from 0 to 1.Edward Tomasz Napierala2015-10-101-1/+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.

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.

* Flip on fast frames support for AR5416 and AR9300 series NICs.Adrian Chadd2015-10-102-8/+2
| | | | | | | | | | | | | | | | | | | | | | 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) Notes: svn path=/head/; revision=289099

| | | | Notes: svn path=/head/; revision=289098
* Return only IIC_Exxxx status values from iicbus-layer functions. Most ofIan Lepore2015-10-092-7/+22
| | | | | | | | | | | | | 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). Notes: svn path=/head/; revision=289097
* Add iic2errno(), a helper function to translate IIC_Exxxxx status values toIan Lepore2015-10-092-0/+24
| | | | | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=289095
* Use IIC_EBUSBSY and IIC_BUSERR status values consistantly across all drivers.Ian Lepore2015-10-097-11/+11
| | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=289093
* Mostly rewrite the imx i2c driver. This started out as an attempt to fixIan Lepore2015-10-091-170/+121
| | | | | | | | | | | | | | | | | | | | | | | | | 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().
