From f5f76ea75dce553631ffb08abc44dcecb68e74d4 Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Mon, 11 Jan 2016 15:17:23 +0000 Subject: [PATCH 01/47] ASoC: qcom: use correct device pointer in dma allocation dev pointer in struct snd_soc_pcm_runtime does not have dma_ops set. In v4.4 kernel dma_ops would end up pointing to dummy_dma_ops in such cases. So attempting to use such device in allocating coherent memory on aarch64 would fail. According to commit 1dccb598df549d892b6450c261da54cdd7af44b4 ("arm64: simplify dma_get_ops") The current behavior of dma_get_ops is to fall back to the global dma_ops when a device has not set its own dma_ops, but only for DT based systems. So, this patch fixes the driver to use correct device pointer while allocating coherent memory, and also deletes un-necessary dma_mask setup on soc_runtime->dev. Without this patch lpass driver would fail with below log: ...

In fact, if the driver is reloaded the values in registers will be whatever they were set to previously. However, the cache needs to be fully populated at probe time to avoid non-atomic allocations during register access. Special case here is imx21-class SSI, since according to datasheet it don't have SACC{ST,EN,DIS} regs. This fixes hard lockup on fsl_ssi module reload, at least in AC'97 mode.

But Atom-DPCM driver does not use common sst code so we cannot include the common SST module in Atom-DPCM driver. So the solution is to have a independent sst-match-acpi module which helps in matching for all the three drivers.

It's because the presence check and the assignment of the buffer is done outside the spinlock for the pool. The fix is to move the check and the assignment into the spinlock. (The current implementation is suboptimal, as there can be multiple unnecessary vmallocs because the allocation is done before the check in the spinlock. But the pool size is already checked beforehand, so this isn't a big problem; that is, the only possible path is the multiple writes before any pool assignment, and practically seen, the current coverage should be "good enough".)

Usually this is OK, but when a write lock is issued between these two read locks, the problem happens: the write lock is blocked due to the first reade lock, and the second read lock is also blocked by the write lock. This eventually deadlocks. The reason is the way rwsem manages waiters; it's queued like FIFO, so even if the writer itself doesn't take the lock yet, it blocks all the waiters (including reads) queued after it. As a workaround, in this patch, we replace the standard down_write() with an spinning loop. This is far from optimal, but it's good enough, as the spinning time is supposed to be relatively short for normal PCM operations, and the code paths requiring the write lock aren't called so often.

The Intel HW team also confirmed that this is needed for SKL. This patch makes the workaround applied to both SKL and BXT platforms. The referred macros are moved and one superfluous macro (IS_BROXTON()) is another one (IS_BXT()) as well.

But in reality, it has been confirmed that the HW irq is issued even during the irq handling. Since we clear the irq status at the beginning, process the interrupt, then exits from the handler, the lately issued interrupt is left untouched without being properly processed. This patch changes the interrupt handler code to loop over the check-and-process. The handler tries repeatedly as long as the IRQ status are turned on, and either stream or CORB/RIRB is handled. For checking the stream handling, snd_hdac_bus_handle_stream_irq() returns a value indicating the stream indices bits. Other than that, the change is only in the irq handler itself.
