Currently, `interrupt_pci9118_ai_dma()` calls `defragment_dma_buffer()`

Ian Abbott [Thu, 27 Nov 2014 11:37:18 +0000 (11:37 +0000)]
staging: comedi: adl_pci9118: try and avoid unnecessary DMA restart

`interrupt_pci9118_ai_dma()` is called on interrupt to transfer data
from DMA buffers into the comedi async data buffer.  Currently it always
restarts DMA.  If double buffering, it restarts DMA on the next DMA
buffer before processing the current DMA buffer, otherwise it restarts
DMA on the same DMA buffer after it has been processed.

For single buffering we can avoid restarting the DMA transfer by
checking the async event flags after the current buffer has been
processed, which is easy.

For double buffering, we need to know how many valid samples there are
in the current buffer before it has been processed and determine whether
there is enough to complete the acquisition.  Call new function
`valid_samples_in_act_dma_buf()` to determine the number of valid
samples in the current DMA buffer, and compare that with the result of
`comedi_nsamples_left()` to determine if DMA needs to be restarted.
(`comedi_nsamples_left()` needs an upper bound to clamp to, so use the
number of valid samples in the DMA buffer plus one for our test.)

It is still possible for DMA to be restarted unnecessarily in the double
buffer case if a `COMEDI_CB_OVERFLOW` event occurs while copying to the
comedi async buffer, but it doesn't really matter.  The ongoing DMA
operation will get disabled when the subdevice's `cancel()` handler is
called when the events are handled later in the interrupt service
routine (as it does currently).

MIPS: tlbex: Fix potential HTW race on TLBL/M/S handlers

There is a potential race when probing the TLB in TLBL/M/S exception
handlers for a matching entry. Between the time we hit a TLBL/S/M
exception and the time we get to execute the TLBP instruction, the
HTW may have replaced the TLB entry we are interested in hence the TLB
probe may fail. However, in the existing handlers, we never checked the
status of the TLBP (ie check the result in the C0/Index register). We
fix this by adding such a check when the core implements the HTW. If
we couldn't find a matching entry, we return back and try again.

the incorrect setup of the STREX backoff delay bit due to a wrong
description in the specification.

Marc Zyngier [Wed, 26 Nov 2014 17:55:31 +0000 (17:55 +0000)]
ARM: tegra: irq: fix buggy usage of irq_data irq field

The crazy gic_arch_extn thing that Tegra uses contains multiple
references to the irq field in struct irq_data, and uses this
to directly poke hardware register.

But irq is the *virtual* irq number, something that has nothing
to do with the actual HW irq (stored in the hwirq field). And once
we put the stacked domain code in action, the whole thing explodes,
as these two values are *very* different:

root@bacon-fat:~# cat /proc/interrupts
            CPU0       CPU1
 16:      25801       2075       GIC  29  twd
 17:          0          0       GIC  73  timer0
112:          0          0      GPIO  58  c8000600.sdhci cd
123:          0          0      GPIO  69  c8000200.sdhci cd

284:        300          0       GIC  85  7000d000.i2c
[...]

Just replacing all instances of irq with hwirq fixes the issue.
