| * solos: Check for rogue received packetsNathan Williams2009-03-251-0/+4
| | | | | | | | | | | | | | | | | | Sometimes there can be received packets with the size field set to 0xFFFF. This seems to only occur after an FPGA or firmware upgrade. This patch discards packets with an invalid size. Signed-off-by: Nathan Williams <nathan@traverse.com.au> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
| * solos: support new FPGA RAM layoutNathan Williams2009-03-251-9/+62
| | | | | | | | | | | | | | | | | | Buffer sizes have been changed to 2048 bytes. Flash upgrades use a dedicated RAM block. Add support for daughterboard. Signed-off-by: Nathan Williams <nathan@traverse.com.au> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
* | drivers/atm: Correct redundant testJulia Lawall2009-07-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | str has already been tested. It seems that this test should be on the recently returned value snr. A simplified version of the semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r exists@ local idexpression x; expression E; @@ if (x == NULL || ...) { ... when forall return ...; } ... when != \(x=E\|x--\|x++\|--x\|++x\|x-=E\|x+=E\|x|=E\|x&=E\|&x\) ( *x == NULL | *x != NULL ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.

* | Replace all DMA_nBIT_MASK macro with DMA_BIT_MASK(n)Yang Hongyang2009-04-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the second go through of the old DMA_nBIT_MASK macro,and there're not so many of them left,so I put them into one patch.I hope this is the last round. After this the definition of the old DMA_nBIT_MASK macro could be removed.

| * solos: Clean up firmware loading codeDavid Woodhouse2009-01-271-136/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We no longer try to load firmware while the ATM is up and running. However, this means that we _do_ make init_module() wait for it, and it takes a long time for now (since we're using ultra-conservative code in the FPGA for that too). The inner loop which uses swahb32p() was by Simon Farnsworth. Simon has patches which migrate us to request_firmware_nowait(), for which we'll actually need to take down the ATM devices, do the upgrade, then reregister them.

| * solos: Fix length header in FPGA transfersDavid Woodhouse2009-01-271-4/+7
| | | | | | | | | | | | | | | | The length field shouldn't ever include the size of the header itself. This fixes the problem that some people were seeing with 1500-byte packets. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
