OK, it's fine to me.

I have no information on that; instruction timings are not defined
at architecture level (architecture reference manual), nor do I find
information in the CPU technical reference manual (which would be
specific to the CPU). Instruction timings tend to be implementation
dependent.
I've always consulted Will Deacon when I've needed to know whether
an instruction is expensive or not.

* Re: [PATCH v2,RESEND] misc: new driver sram_uapi for user level SRAM access

Hi, Greg, Arnd,
Thank you for your comments first, and then really very very very sorry
for driving Greg to sigh and I hope there would be chance to share Moutai
(rather than whisky, we drink it much, a kind of Baijiu), after the virus.
Back to the comments, I'd like to do a bit of documentation or explanation first,
which should have been done early or else there would not be so much to explain:
1. What I have been trying to do is to access the Freescale Cache-SRAM device form
user level;
2. I implemented it using UIO, which was thought of non-proper;
3. So I implemented it here to create a misc device as a interface between Kernel
and user space applications, as the comments of Scott suggested;
[Link for 2 & 3: https://lore.kernel.org/patchwork/patch/1225798/]
4. This is exactly a shim of Cache-SRAM hardware level driver, and it would use
apis provided by the hardware driver to do the allocation and free work of
SRAM memory;
5. The file drivers/misc/sram.c actually has done some abstractions for SRAM access,
but it is used as a static way that resources are defined within devicetree;
6. This patch is to reach a way that allocate and release SRAM memory dynamically
which is much more convenient for user space applications, and for another reason,
the Cache-SRAM of Freescale is kind of not compatible with drivers/misc/sram.c;
So I implemented the sram_uapi.c as following:
1. Create a misc device as a interface that support ioctl and mmap for memory access;
2. For that I think this could be used for any SRAM devices that would support dynamic
memory allocation and release, I create sram_api_list as follow:
static DEFINE_MUTEX(sram_api_list_lock);
static LIST_HEAD(sram_api_list);
and different SRAM devices could add their apis to the sram_api_list
which could be used for the allocation from them;
a. int sram_api_register(struct sram_api *sa);
b. int sram_api_unregister(struct sram_api *sa);
c. ioctl case SRAM_UAPI_IOC_SET_SRAM_TYPE;
the register and unregister api are exported for any SRAM drivers to do this,
and maybe user could chose one with ioctl to allocate;
[maybe only one SRAM device available currently and the implementation is redundant]
3. For each fd that opened, a sram_uapi would be created:
struct sram_uapi {
struct list_head res_list;
struct sram_api *sa;
};
The res_list would be a list of resources that allocated attached to it:
struct sram_resource {
struct list_head list;
struct res_info info;
phys_addr_t phys;
void *virt;
struct vm_area_struct *vma;
struct sram_uapi *parent;
};
The sa is a pointer to the apis registered by hardware SRAM driver as descibed earlier,
and when a fd is attached to it, kref it once;
And for the resources, it is accessed by the process only so I did not use a lock here,
and as Greg commented, lock is needed for the fd sharement.
4. The exported apis are currently not reference and I would add another patch series
for Freescale Cache-SRAM to use the api sram_api_register to register its allocation
and free api, as well as sram_api_unregister for unregistering;
Actually, I implemented the api list another way in v1, but was commented by Arnd not a
better way.
[https://lore.kernel.org/patchwork/patch/1226689/]
Then for the comments:
1. Ioctl: I will move the block to uapi, and use static length definition of __be64;
2. Naming: as Greg commented, so hard, and how do you think of
sram_dynamic(as compared to drivers/misc/sram.c)?
3. API list: only one SRAM device? But however, this is a shim, and hardware level
SRAM driver(s) should be enabled to register or init the apis for real allocation;
4. Test: My team and me myself did not cover it, especially newly added kref, and that
is really really so wrong of us, and I will make efforts to test for every logical path
next time, and this would never ever happen. Really sorry for it.

Allocation and free apis are really needed, while name maybe is just

Like commets from Scott, I used the fd to allocate a lot of memory areas and they are
managed with different offset. So I just need to keep them in a sequence and no overlap.
The parent is useless and I will delete it. Anyway, things should be done before put it in.
I may change it according to the comments from Scott, that a fd only be attached to one
memory area which looks exactly like the thing in drivers/misc/sram.c. And then, this block
is useless and will be dropped.

Yes, a shim, and sram_api_register exported to be called by hardware driver
to register it. Params should be checked and I guess the size checked by
lower alloc api?(-ENOMEM or something be returned by it if not afforded to?)
Actually in v1, I used a array to reference the apis statically, and wrapped
with specific MICROs, and changed it this way according to the comments of Arnd.

Tell the userspace the offset of area within the fd, which is the key
as you mentioned upper, and could be used for SRAM_UAPI_IOC_FREE to release,
and mmap to finally attach it to the vma of user process.

I hesitated a lot about whether to hide the kernelcore/movablecore and
related code behind an #ifdef.
In the end I've decided to keep the code compiled unconditionally as it
is anyway __init and no sane person would pass "kernelcore=" to the
kernel on a UMA system.

It's 'compat' from 'compatibility'. This is kinda "the old way" and the
version that was defined when CONFIG_HAVE_MEMBLOCK_NODE_MAP=y is the
"new way", so I picked 'compat' for backwards compatibility.
Anyway, it will go away later in pacth 19.

Not sure it's really worth it.
This patch anyway only moves the code around without any actual changes.

* [PATCH] ASoC: fsl_esai: Remove expensive print in irq handler

To: timur, nicoleotsuka, Xiubo.Lee, festevam, broonie, perex, tiwai,
alsa-devel
Cc: linuxppc-dev, linux-kernel
Use dev_dbg instead of dev_err in irq handler, the dev_err
is expensive, we don't need the message to be printed everytime,
which is almost a debug option.

FWIW, I've seen something similar in a slightly different context,
c.f. [1].
Basically, the issue is that on anything but x86_64 (and perhaps arm64
IIRC), arch_get_random_long() is unavailable and thus, get_random_u64()
falls through to that batched extract_crng() extraction. That is, it
extracts eight random longs from the chacha20 based RNG at once and
batches them up for consumption by the current and subsequent
get_random_u64() invocations. Which is in line with your observation
that get_random_u64() returned zero exactly eight times in a row.
The fact that extract_crng() actually extracted eight successive zero
values surprised me though. But from looking at chacha20_block(), called
from _extract_crng() with the primary_crng instance's state buffer as
input, it seems like a zeroed state buffer gets identity transformed and
that all this fancy shifting and rolling and whatnot in chacha_permute()
would have no effect at all. So I suppose that the primary_crng's state
buffer is still zeroed out at that point during boot.
Thanks,
Nicolai

* [PATCH v2 1/2] cpufreq: qoriq: convert to a platform driver
From: Mian Yousaf Kaukab @ 2020-04-21 8:29 UTC (permalink / raw)
To: linux-pm, andy.tang, sboyd, linux-clk, rjw, shawnguo, leoyang.li
Cc: Mian Yousaf Kaukab, viresh.kumar, linuxppc-dev, linux-kernel,
linux-arm-kernel
The driver has to be manually loaded if it is built as a module. It
is neither exporting MODULE_DEVICE_TABLE nor MODULE_ALIAS. Moreover,
no platform-device is created (and thus no uevent is sent) for the
clockgen nodes it depends on.
Convert the module to a platform driver with its own alias. Moreover,
drop whitelisted SOCs. Platform device will be created only for the
compatible platforms.

* [PATCH v2] powerpc/pseries: Make vio and ibmebus initcalls pseries specific
From: Oliver O'Halloran @ 2020-04-21 8:15 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Tyrel Datwyler, Oliver O'Halloran
The vio and ibmebus buses are used for pseries specific paravirtualised
devices and currently they're initialised by the generic initcall types.
This is mostly fine, but it can result in some nuisance errors in dmesg
when booting on PowerNV on some OSes, e.g.
[ 2.984439] synth uevent: /devices/vio: failed to send uevent
[ 2.984442] vio vio: uevent: failed to send synthetic uevent
[ 17.968551] synth uevent: /devices/vio: failed to send uevent
[ 17.968554] vio vio: uevent: failed to send synthetic uevent
We don't see anything similar for the ibmebus because that depends on
!CONFIG_LITTLE_ENDIAN.
This patch squashes those by switching to using machine_*_initcall() so the bus
type is only registered when the kernel is running on a pseries machine.

I wasn't aware of vdsotest, but I suppose it should be fixed in there
as well. It's only one extra call that is supposed to be available on
all 32-bit architectures.
The other thing to try is musl libc 1.2, or any distro based on it.
https://distfiles.adelielinux.org/adelie/1.0/iso/rc1/ has a ppc32
image file.
I think this is all you should need to do to enable vdso in musl:

Mainline glibc still doesn't have it, I don't know when it will,
presumably either
the coming 2.32 release, or 2.33. There is a tree at
https://github.com/lmajewski/y2038_glibc/commits/y2038_edge that has the
necessary changes, and it is slowly getting merged upstream.

We don't need yet another open coded allocator. If you really need to do this
then use include/linux/genalloc.h, but maybe keep it simple and just have one
allocaton per file descriptor so you don't need to manage fd offsets?

What if the allocation is more than one page, and the user mmaps starting

Just expose one device per backing SRAM, especially if the user has any reason
to care about where the SRAM is coming from (correlating sysfs nodes is much
more expressive than some vague notion of "type").

Missing EFAULT test (here and elsewhere), and res leaks on error.

Do we really need multiple allocators, or could the backend be limited to just
adding regions to a generic allocator (with that allocator also serving in-
kernel users)?
If sram_alloc is supposed to return a virtual address, why isn't that the
return type?

ENOSPC might be more appropriate, as this isn't general-purpose RAM.

So you can just delete any arbitrary offset, even if you weren't the one that
allocated it? Even if this isn't meant for unprivileged use it seems error-

Cheers, thanks for this. I think being consistent is worthwhile, as it's
the definitions themselves that are weird and we can conceivably clean
that up as a separate patch.
So,

Looks like Andrew already picked it up (thanks!)

Yes that was one of the objective, be able to add that as a second step.
First objective was adding the missing clocks and increasing
maintainability.
I can add a patch for that now, it looks easy, but how do I test it ?
vdsotest from Nathan doesn't seem to test that.

How modern ? I have glibc 2.28, the only symbols it seems to know are
(extracted with 'strings') :
__vdso_clock_gettime
__vdso_time
__vdso_get_tbfreq
__vdso_getcpu
__vdso_clock_getres
__vdso_sigtramp32
__vdso_sigtramp_rt32
__vdso_gettimeofday

The BARs stay in the same place and as far as MMIO is concerned
nothing has changed. For MMIO the PHB uses the MMIO address to find a
PE via the M64 BAR table, but for DMA it uses a *completely* different
mechanism. Instead it takes the BDFN (included in the DMA packet
header) and the Requester Translation Table (RTT) to map the BDFN to a
PE. Normally you would configure the PHB so the same PE used for MMIO
and DMA, but you don't have to.

Yes, we could do that, but do we want to?
I was thinking we should try minimise the number of DMA-only PEs since
it complicates the EEH freeze handling. When MMIO and DMA are mapped
to the same PE an error on either will cause the hardware to stop
both. When seperate PEs are used for DMA and MMIO you lose that
atomicity. It's not a big deal if DMA is stopped and MMIO allowed
since PAPR (sort-of) allows that, but having MMIO frozen with DMA
unfrozen is a bit sketch.

There's been no official FW releases with a skiboot that supports the
phb get/set option opal calls so the only systems that can actually
take advantage of it are our lab systems. It might still be useful for
future systems, but I'd rather something that doesn't depend on FW
support.

We don't bother building the patch if the base build fails. The
majority of the time this is extra unnecessary work, and from what I've
seen most build upstream build breaks aren't fixed from within the
powerpc tree.
We might change this in future because you're right, it should show
that this patch fixes the build.

I don't understand, why does snowpatch still reports it can't test the

Hello,
Since the PowerPC updates 5.7-1 I get the following warnings during the
linking.
5.7-rc2:
MODPOST vmlinux.o
WARNING: modpost: vmlinux.o(.text.unlikely+0x1a0): Section mismatch in
reference from the function .early_init_mmu() to the function
.init.text:.radix__early_init_mmu()
The function .early_init_mmu() references
the function __init .radix__early_init_mmu().
This is often because .early_init_mmu lacks a __init
annotation or the annotation of .radix__early_init_mmu is wrong.
WARNING: modpost: vmlinux.o(.text.unlikely+0x1ac): Section mismatch in
reference from the function .early_init_mmu() to the function
.init.text:.hash__early_init_mmu()
The function .early_init_mmu() references
the function __init .hash__early_init_mmu().
This is often because .early_init_mmu lacks a __init
annotation or the annotation of .hash__early_init_mmu is wrong.

Did you modify the mmu code? Please find attached my kernel config.
Thanks,
Christian

* [PATCH] powerpc/dt_cpu_ftrs: Add MMA feature
From: Alistair Popple @ 2020-04-21 5:50 UTC (permalink / raw)
To: linuxppc-dev; +Cc: mikey, npiggin, oohall, Alistair Popple
MMA (matrix multiply accumulate) instructions are only permitted to
execute when enabled via a PCR bit. Enable this bit when support is
advertised by a CPU device tree feature.

One example of a problem device is AMD GPU with 64bit video PCI function
and 32bit audio, no?
What PEs will they get assigned to now? Where will audio's MMIO go? It
cannot be the same 64bit MMIO segment, right? If so, it is a separate PE
already. If not, then I do not understand "we're free to assign whatever
PE number we want.

Oooor we could just have 1 DMA window (or, more precisely, a single
"TVE" as it is either window or bypass) per a PE and give every function
its own PE and create a window or a table when a device sets a DMA mask.
I feel I am missing something here though.

If CONFIG_HIGHMEM is enabled, the above judgement is always true,
wondering what's the purpose we have to do like this. It's not related
to this patch though.

Wondering if this change will impact anything. Before, those ARCHes with
CONFIG_HAVE_MEMBLOCK_NODE_MAP support movable_node. With this patch
applied, those ARCHes which don't support CONFIG_HAVE_MEMBLOCK_NODE_MAP
can also have 'movable_node' specified in kernel cmdline.

Does it mean those ARCHes which don't support
CONFIG_HAVE_MEMBLOCK_NODE_MAP before, will have 'kernelcore=' and

Is it compact zone which has continuous memory region, and the
compat here is typo? Or it's compatible zone? The name seems a little

It's not a problem. I would actually prefer to use PAGE_KERNEL since the
mapping is really for a kernel page. On radix using PAGE_KERNEL allows us
to avoid the KUAP functions due to the HW implementation (AMR and EAA).

Here it's apparently removing CONFIG_HAVE_MEMBLOCK_NODE_MAP too early,
it should be done in patch 3, and its #end is kept there. I just found
it when I almost became dizzy in reviewing patch 3.
