* [PATCH 0/6] iommu/arm-smmu: Misc modifications to support SMMUs on Calxeda ECX-2000
From: Andreas Herrmann @ 2014-01-30 18:18 UTC (permalink / raw)
  To: linux-arm-kernel

Hi,

This is v5 of my arm-smmu changes (to support SMMUs on Calxeda ECX-2000).

Patches are based on v3.13.

Changes to previous version are
- use iommu_group notifier instead of bus notifier
- remove superfluous call to arm_smmu_add_device in
  notifier function
- free bitmap that's used for checking of duplicate stream IDs
- hopefully addressed all issues for the "SMR allocator" patch
  (see http://marc.info/?l=linux-arm-kernel&m=139040446813960)
- reorder patches to put the notifier change last (in case there are
  still objections to this the rest could be merged I think)


I omitted the patches that are device-tree related (of, dts,
documentation) or ARM dma-mapping.c related. I'll work on an update of
the dma-mapping change (to automatically increase the mapping size)
separately.

Changelog:
v4:

* [PATCH v2] ARM: keystone: dts: drop "msmcsram" clock node
From: Ivan Khoronzhuk @ 2014-01-30 18:10 UTC (permalink / raw)
  To: linux-arm-kernel

At late init all unused clocks are disabled. So clocks that were not
get before will be gated. In Keysone 2 SoC we have at least one
necessary clock that is not used by any driver - "msmcsram". This
clock is necessary, because it supplies the Multicore Shared Memory
Controller (MSMC). MSMC is the coherency interconnect and all the
coherent masters are connected to it including devices which are not
under Linux OS control. MSMC clock should not be touched even in low
power states.

So drop the clock node, otherwise 'clk_ignore_unused' parameter will
disable the clock leading to system stall.

* [PATCH] ARM: dts: msm: split out msm8660 and msm8960 soc into dts include
From: Kumar Gala @ 2014-01-30 18:08 UTC (permalink / raw)
  To: linux-arm-kernel

Pull the SoC device tree bits into their own files so other boards based
on these SoCs can include them and reduce duplication across a number of
boards.

Ah, I missed the other __NR_* uses in the generic audit_*.h files. Below
is an attempt to add compat __NR_* definitions to arm64 unistd32.h.
There are other ways of doing this and still avoid collision with the
native ones but I thought that's the easiest. Note that these are not
uapi headers, so they are just for the kernel. Compile-tested only (and
please check, maybe my vim macros and regexp got something wrong):

(and in the process I found two new AArch32 syscalls which I'll add to
the compat layer)

Subject: [PATCH] arm64: Add __NR_* definitions for compat syscalls

This patch adds __NR_* definitions to asm/unistd32.h, moves the
__NR_compat_* definitions to asm/unistd.h and removes all the explicit
unistd32.h includes apart from the one building the compat syscall
table. The aim is to have the compat __NR_* definitions available but
without colliding with the native syscall definitions.

The clobbers. For example:

arch/arm64/kvm/sys_regs.c:

        /* Make sure noone else changes CSSELR during this! */
        local_irq_disable();
        /* Put value into CSSELR */
        asm volatile("msr csselr_el1, %x0" : : "r" (csselr));
        isb();
        /* Read result out of CCSIDR */
        asm volatile("mrs %0, ccsidr_el1" : "=r" (ccsidr));
        local_irq_enable();

Just about everything can be re-ordered in that block, because the asm
volatile statements don't have "memory" clobbers.

I think it's worth checking the rest of the kernel, too.

safe_halt() is "sti; hlt" and so very much does the irq_enable.

Yeah, but those are driver problems, right? 1400 suspends is very
nice, and it shows that the core is working. That should be enough for
merge; driver problems can be solved later.

Thanks,

Sorry, the problem was on my end.  I must have mistakenly marked one

too.  Sorry about that.

* [PATCH v2] clk: keystone: gate: fix clk_init_data initialization
From: Ivan Khoronzhuk @ 2014-01-30 18:03 UTC (permalink / raw)
  To: linux-arm-kernel

The clk_init_data struct is allocated in the stack. All members of
this struct should be initialized before using otherwise it will
lead to unpredictable situation as it can contain garbage.

Ultimately the clk->flag field contains garbage. In my case it leads
that flag CLK_IGNORE_UNUSED is set for most of clocks. As result a
bunch of unused clocks cannot be disabled.

So initialize flags in this structure too.

I better think about a 'normal' DT definition:

- in the DT, define the tda998x in a i2c subnode:

  &i2c0 {
	tda998x: hdmi-encoder {
		compatible = "nxp,tda998x";
		reg = <0x70>;
		/* the video ports are OK by default */
		/* define the interrupt if you want to use it */
	};
  };

- in tilcdc_slave.c, in the function slave_encoder_create(), instead of
  using drm_i2c_encoder_init(), do quite the same, but without calling
  request_module() nor i2c_new_device().

  This can be done as follows (the code is not compiled):

--------------------8<---------------------
static struct drm_encoder *slave_encoder_create(struct drm_device *dev,
		struct slave_module *mod)
{
	struct slave_encoder *slave_encoder;
	struct drm_encoder *encoder;
	int ret;
/* ------ added ------ */
	struct device_node *np;
	static const struct of_device_id tda_dt[] = {
		{ .compatible = "nxp,tda998x" },
		{ },
	};
/* ------ end added ------ */

	... no change ...

	 drm_encoder_helper_add(encoder, &slave_encoder_helper_funcs);

/* ------ added ------ */

	/* search the tda998x device */
	np = of_find_matching_node_and_match(NULL, tda_dt, NULL);
	if (np && of_device_is_available(np)) {
		struct i2c_client *i2c_client;
		struct drm_i2c_encoder_driver *encoder_drv;
		struct module *module;

					/* the tda998x is in the DT */

		i2c_client = of_find_i2c_device_by_node(np);
		of_node_put(np);
		if (!i2c_client) {
			dev_err(dev->dev, "no tda998x i2c client\n");
			goto fail;
		}

		to_encoder_slave(encoder)->bus_priv = i2c_client;

		encoder_drv = to_drm_i2c_encoder_driver(
				to_i2c_driver(i2c_client->dev.driver));

		/* lock the tda998x module in memory */
		module = to_i2c_driver(i2c_client->dev.driver)->driver.owner;
		if (!module || !try_module_get(module)) {
			dev_err(dev->dev, "cannot get module %s\n", module->name);
			goto fail;
		}

		ret = encoder_drv->encoder_init(i2c_client, dev, encoder_slave);
		if (ret < 0) {
			dev_err(dev->dev, "slave encoder init failed\n");
			module_put(module);
			goto fail;
		}
					/* set_config is useless */
		return encoder;
	}

/* ------ end added ------ */

	ret = drm_i2c_encoder_init(dev, to_encoder_slave(encoder), mod->i2c, &info);
	if (ret)
		goto fail;

	return encoder;

fail:
	slave_encoder_destroy(encoder);
	return NULL;
}
--------------------8<---------------------

When the tda998x is in the DT, the i2c_client is already created.
It must not be freed, and so, the function drm_i2c_encoder_destroy()
must not be called. But, the module must be explicitly unlocked in
slave_encoder_destroy(), and then, there must be some flag in the
structures for this job to be done...

Rob,

Do you agree on increasing MAX_PHANDLE_ARGS to 32?

Or should this be done when someone (e.g. Suravee) submits a DTS
update with an SMMU node description containing more than 16 stream
IDs for a master device?

Cool, thanks. Agreed, but I thought it'd be nice to list the simulator class.

This isn't particularly scientific, but maybe a practical criteria could be
that it's mentioned in this thread? I think if we word the introduction to the
list clearly, readers will know that that these are just a few examples known
to be in use when the binding was written and by no means required. I think
that providing more information is more likely to fix the incorrect assumption
than providing less information.

Yes, I assumed you would include Xen. I'm not aware of any others*, but
perhaps those who do could speak up about them?

(*I do use Angel semihosting and DCC from time to time, but I've never seen
devicetree bindings for these facilities. I'm not sure whether they count in
this context.)

Thanks,
Christopher

So Marc's plan has actually happened. Neat. In that case is there even
any point in listing explicit compatiblity strings (except perhaps as a
historical note) -- I can just say that this is the fallback/default
machine?

I'll leave the virt_init change to a separate patch if that's ok.

I will ack the patch that removes the mach-virt directory altogether!

It might be worth noting in the changeset comment that the 'compatible'
string is actually no longer needed on newer kernels: All the members
of the machine descriptor are now the defaults (we should remove the
virt_init() function as well), and the fallback machine descriptor should
work just fine if any other string gets passed.

Ok, I think the mess is coming from 'default_idle' which does not 
re-enable the local_irq but used from different places like 
amd_e400_idle and apm_cpu_idle.

void default_idle(void)
{
         trace_cpu_idle_rcuidle(1, smp_processor_id());
         safe_halt();
         trace_cpu_idle_rcuidle(PWR_EVENT_EXIT, smp_processor_id());
}

Considering the system configured without cpuidle because this one 
*always* enable the local irq, we have the different cases:

x86_idle = default_idle();
==> local_irq_enable is missing

x86_idle = amd_e400_idle();
==> it calls local_irq_disable(); but in the idle loop context where the 
local irqs are already disabled.
==> if amd_e400_c1e_detected is true, the local_irq are enabled
==> otherwise no
==> default_idle is called from there and does not enable local_irqs

This WARN should disappear. It was there because it was up to the 
backend cpuidle driver to enable the irq. But in the meantime, that was 
consolidated into a single place in the cpuidle framework so no need to 
try to catch errors.

What about (based on this patchset).

Right. 1984, here we come. I'll disappear for a while, rewriting the
history. More seriously, that was just me scheming to get it merged,
hiding my cunning plan for mach-virt world domination!

"Add support for the smallest, dumbest possible platform, to be
 used as a guest for KVM or other hypervisors.

 It only mandates a GIC and architected timers"

(your original commit message :-P)

I can word it more like that for sure, along with the alternative
wording suggested by Christopher/Stefano to clarify the intent that
everything comes from DTB and removal of the specific requirements for
GIC/timer/PSCI I think that suit the (new) intention better?

I can mention this, although I don't think the list needs to be
exhaustive.

Yes, this is what I was trying to say, I'll update with something along
those lines.

Under what criteria would something be eligible/appropriate to be
listed? I was trying to avoid "advocating" any particular type of PV
devices. We already have something of a problem with people incorrectly
assuming that mach-virt == virtio, which is not the case.

If we did want to include an explicit list here at a minimum I would
also want to include the Xen PV devices as well and surely there would
be others which ought to be included too.

* [PATCH 7/7] ARM: mvebu: enable audio options in mvebu_defconfig
From: Thomas Petazzoni @ 2014-01-30 17:14 UTC (permalink / raw)
  To: linux-arm-kernel
In-Reply-To: <1391102051-5319-1-git-send-email-thomas.petazzoni@free-electrons.com>

Since at least the Armada 370 SoC has audio support, it makes sense to
enable the corresponding kernel configuration options in
mvebu_defconfig.

* [PATCH 6/7] ARM: mvebu: add audio support to Armada 370 DB
From: Thomas Petazzoni @ 2014-01-30 17:14 UTC (permalink / raw)
  To: linux-arm-kernel
In-Reply-To: <1391102051-5319-1-git-send-email-thomas.petazzoni@free-electrons.com>

This commit adds the necessary Device Tree informations to enable
audio support on the Armada 370 DB platform. In details it:

 * Instantiates the CS42L51 audio codec on the I2C0 bus, and
   configures this bus with the appropriate pin-muxing configuration.

 * Enables the I2S audio controller, and configures it with the
   appropriate pin-muxing configuration.

 * Through hog pins, ensures that the other pins possibly used for I2S
   are muxed with another function than I2S.

* [PATCH 3/7] sound: soc: add ASoC board driver for Armada 370 DB
From: Thomas Petazzoni @ 2014-01-30 17:14 UTC (permalink / raw)
  To: linux-arm-kernel
In-Reply-To: <1391102051-5319-1-git-send-email-thomas.petazzoni@free-electrons.com>

This commit adds a simple ASoC board driver fo the Armada 370
Development Board, which connects the audio unit of the Armada 370 SoC
to the I2C-based CS42L51.

For now, only the analog audio input and output through the CS42L51
are supported, but in the near future, digital audio input and output
support will be added through SPDIF.
