The 20160422 ACPICA kernel-resident subsystem updates are linuxized based
on the linux-pm/linux-next branch.
NOTE:
1. Indentation improvement
The [PATCH 02] is a result of an ACPICA release process fix. It requires
much of human intervention, and many linuxized patches in my hand that are
not upstreamed to the ACPICA are burnt by this commit, which takes weeks or
months to recover. So hope we can do it only once. The [PATCH 01] can
reduce the painful manual work when we have to re-do it.
2. AcessWidth/BitOffset support
The old way of hardware access code has been working for many years. The
commits in this release cycle enables AccessWidth/BitOffset support. Though
the commits of AccessWidth/BitOffset support are written in the regression
safer way, it may still break users because of unknown cases. But we need
to have it in the upstream so that it can be used by as many as possible
users in order to obtain the feedback to reveal the unknown cases.
The patchset has passed the following build/boot tests.
Build tests are performed as follows:
1. i386 + allyes
2. i386 + allno
3. i386 + default + ACPI_DEBUGGER=y
4. i386 + default + ACPI_DEBUGGER=n + ACPI_DEBUG=y
5. i386 + default + ACPI_DEBUG=n + ACPI=y
6. i386 + default + ACPI=n
7. x86_64 + allyes
8. x86_64 + allno
9. x86_64 + default + ACPI_DEBUGGER=y
10.x86_64 + default + ACPI_DEBUGGER=n + ACPI_DEBUG=y
11.x86_64 + default + ACPI_DEBUG=n + ACPI=y
12.x86_64 + default + ACPI=n
Boot tests are performed as follows:
1. i386 + default + ACPI_DEBUGGER=y
2. x86_64 + default + ACPI_DEBUGGER=y
Where:
1. i386: machine named as "Dell Inspiron Mini 1010"
2. x86_64: machine named as "HP Compaq 8200 Elite SFF PC"
3. default: kernel configuration with following items enabled:
All hardware drivers related to the machines of i386/x86_64
All "drivers/acpi" configurations
All "drivers/platform" drivers
All other drivers that link the APIs provided by ACPICA subsystem
The divergences checking result:
Before applying (20160318 Release):
494 lines
After applying (20160422 Release):
485 lines
The reduction is caused by recently merged module level improvement.

ACPICA commit b2294cae776f5a66a7697414b21949d307e6856f
This patch removes unwanted spaces for typedef. This solution doesn't cover
function types.
Note that the linuxize result of this commit is very giant and should have
many conflicts against the current Linux upstream. Thus it is required to
modify the linuxize result of this commit and the commits around it
manually in order to have them merged to the Linux upstream. Since this is
very costy, we should do this only once, and if we can't ensure to do this
only once, we need to revert the Linux code to the wrong indentation result
before merging the linuxize result of this commit. Lv Zheng.

ACPICA commit c49a751b4dae7baec1790748a2b4b6e8ab599f51
For Access Size = 0, it actually can use user expected access bit width.
This patch implements this.
Besides of the ACPICA upstream commit, this patch also includes a fix fixing
the issue reported by the FreeBSD community.
The old register descriptors are translated in acpi_tb_init_generic_address()
with access_width being filled with 0. This breaks code in
acpi_hw_get_access_bit_width() when the registers are 16-bit IO ports and their
bit_width fields are filled with 16. The rapid fix is meant to make code
written for acpi_hw_get_access_bit_width() regression safer before the issue is
correctly fixed from acpi_tb_init_generic_address(). Reported by
John Baldwin <jhb@freebsd.org>, fixed by Lv Zheng <lv.zheng@intel.com>, tested
by Jung-uk Kim <jkim@freebsd.org>.

ACPICA commit c23034a3a09d5ed79f1827d51f43cfbccf68ab64
A regression was reported to the shift offset >= width of type.
This patch fixes this issue. BZ 1270.
This is a part of the fix because the order of the patches are modified for
Linux upstream, containing the cleanups for the old code. Lv Zheng.

[Lv Zheng]
This is the result after running ACPICA release automation tool from the following point:
https://github.com/acpica/acpica/commit/e714615f
The command to confirm the result is:
# generate/linux/gen-repo e714615f
The spaces added by this patch are fixed by this ACPICA commit:
https://github.com/acpica/acpica/commit/b2294cae
This commit is released in this ACPICA release cycle as [PATCH 02].
So what have been made wrong here will be made correct by PATCH 02.

[Lv Zheng]
ACPICA release scripts have already been aware of u8 as a type, so the indentation is not wrong after running ACPICA release scripts.
While acpi_size is not, acpi_size is fixed by the above mentioned commit:
https://github.com/acpica/acpica/commit/b2294cae
This commit is released in this ACPICA release cycle as [PATCH 02].
So what haven't been fixed here will be fixed by [PATCH 02].

The only way to make it looking correct is to merge PATCH 01 into PATCH 02.
But I need to make sure that I won't have to make this release cycle more than twice...
Otherwise I need to keep them separated in order to reduce human interventions.

The 20160422 ACPICA kernel-resident subsystem updates are linuxized based
on the linux-pm/linux-next branch.
NOTE:
1. Indentation improvement
The [PATCH 01] is a result of an ACPICA release process fix. It requires
much of human intervention, and many linuxized patches in the developers'
local working repositories that are not upstreamed to the ACPICA will be
burnt by this commit, and may take weeks or months for the developers to
recover. So hope we can do it correctly and rapidly.
2. AcessSize/BitOffset support
ACPICA implements ACPI hardware register accesses using ACPI 1.0 style,
which contains only BLK/LEN fields. ACPI 2.0 starts to use Generic Address
Structure to define hardware registers, the ACPI 1.0 fields can be
translated into Address/BitWidth fields and ACPI 2.0 defines new
AccessSize/BitOffset fields as an extension. While the ACPICA code of the
GAS support is still Address/BitWidth aware only. This becomes one of the
significant ACPI 2.0 gaps in ACPICA.
But as we have already switched the address favor to 64-bit (aka., favor
GAS descriptors) and there is almost no regression report, enabling
AccessSize/BitOffset awareness seems to be just a theoretical issue because
there is no existing users requiring this, and enabling it might just be an
ecosystem enabling work for the future users.
So the most important thing of this improvement is to ensure regression
safer by keeping old behavior working. [PATCH 08] is thus generated for
this purpose. After ensuring this, we need this improvement to appear in
the upstream to have more users to test it so that we can learn unknown
cases from the feedback.
The patchset has passed the following build/boot tests.
Build tests are performed as follows:
1. i386 + allyes
2. i386 + allno
3. i386 + default + ACPI_DEBUGGER=y
4. i386 + default + ACPI_DEBUGGER=n + ACPI_DEBUG=y
5. i386 + default + ACPI_DEBUG=n + ACPI=y
6. i386 + default + ACPI=n
7. x86_64 + allyes
8. x86_64 + allno
9. x86_64 + default + ACPI_DEBUGGER=y
10.x86_64 + default + ACPI_DEBUGGER=n + ACPI_DEBUG=y
11.x86_64 + default + ACPI_DEBUG=n + ACPI=y
12.x86_64 + default + ACPI=n
Boot tests are performed as follows:
1. i386 + default + ACPI_DEBUGGER=y
2. x86_64 + default + ACPI_DEBUGGER=y
Where:
1. i386: machine named as "Dell Inspiron Mini 1010"
2. x86_64: machine named as "HP Compaq 8200 Elite SFF PC"
3. default: kernel configuration with following items enabled:
All hardware drivers related to the machines of i386/x86_64
All "drivers/acpi" configurations
All "drivers/platform" drivers
All other drivers that link the APIs provided by ACPICA subsystem
The divergences checking result:
Before applying (20160318 Release):
494 lines
After applying (20160422 Release):
485 lines
The reduction is caused by recently merged module level improvement.

ACPICA: Refactor evaluate_object to reduce nesting
ACPICA: ACPI 6.1: Support for new PCCT subtable
ACPICA: ACPI 6.0: Update _BIX support for new package element

ACPICA commit b2294cae776f5a66a7697414b21949d307e6856f
This patch removes unwanted spaces for typedef. This solution doesn't cover
function types.
Note that the linuxize result of this commit is very giant and should have
many conflicts against the current Linux upstream. Thus it is required to
modify the linuxize result of this commit and the commits around it
manually in order to have them merged to the Linux upstream. Since this is
very costy, we should do this only once, and if we can't ensure to do this
only once, we need to revert the Linux code to the wrong indentation result
before merging the linuxize result of this commit. Lv Zheng.

ACPICA commit c49a751b4dae7baec1790748a2b4b6e8ab599f51
For Access Size = 0, it actually can use user expected access bit width.
This patch implements this.
Besides of the ACPICA upstream commit, this patch also includes a fix fixing
the issue reported by the FreeBSD community.
The old register descriptors are translated in acpi_tb_init_generic_address()
with access_width being filled with 0. This breaks code in
acpi_hw_get_access_bit_width() when the registers are 16-bit IO ports and their
bit_width fields are filled with 16. The rapid fix is meant to make code
written for acpi_hw_get_access_bit_width() regression safer before the issue is
correctly fixed from acpi_tb_init_generic_address(). Reported by
John Baldwin <jhb@freebsd.org>, fixed by Lv Zheng <lv.zheng@intel.com>, tested
by Jung-uk Kim <jkim@freebsd.org>.

ACPICA commit c23034a3a09d5ed79f1827d51f43cfbccf68ab64
A regression was reported to the shift offset >= width of type.
This patch fixes this issue. BZ 1270.
This is a part of the fix because the order of the patches are modified for
Linux upstream, containing the cleanups for the old code. Lv Zheng.

ACPICA commit 96ece052d4d073aae4f935f0ff0746646aea1174
ACPICA commit 3d8583a054e410f2ea4d73b48986facad9cfc0d4
This patch adds access_width/bit_offset support in acpi_hw_read().
This also enables GAS definition where bit_width is not a power of
two. Lv Zheng.

This (together with "... Add access_width/bit_offset support in
acpi_hw_write") breaks Xen guests using older QEMU which doesn't support
4-byte IO accesses.
Why not return "reg->bit_width?:max_bit_width" ? This will preserve
original behavior.

Did you figure out why we get here in the first place, instead of taking the
first "return"? I.e. isn't the issue the apparently wrong use of the second
ACPI_IS_ALIGNED() above? Afaict it ought to be
ACPI_IS_ALIGNED(address, reg->bit_width / 8)...

We are trying to access address 0x...b004 (PM1a control) so yes, fixing
alignment check would probably resolve the problem that we are seeing now.
However, for compatibility purposes we may consider not doing any checks
and simply return bit_width if access_width is not available.

Interestingly enough I bisected what I thought was a completely
different problem to this patch as well.
Something is messed up with 32-bit dom0 booting (so no QEMU) on one
machine in my pool. First error that I see is
pcieport 0000:00:02.0: can't find IRQ for PCI INT A; probably buggy
MP table
I'll look at this tomorrow, hopefully.

[Lv Zheng]
Let me ask 2 questions:
A. Was this a bug of the older qemu?
If so, you only need a quirk mechanism for old qemu to work.
And it would be better to provide the quirk inside of the older qemu.
B. Could you provide the detailed register description?
The case I saw from the freebsd community around the qemu is a bit_width = 16 case.
Which is a conversion result of acpi_tb_init_generic_address().
Thus:
1. reg->access_width is always 0
2. reg->bit_offset is always 0
3. reg->bit_width is either 8 or 16
So they can be covered by this check:
if (reg->access_width) {
if (!reg->bit_offset && reg->bit_width &&
ACPI_IS_POWER_OF_TWO(reg->bit_width) &&
ACPI_IS_ALIGNED(reg->bit_width, 8))
I just enhanced it with the address check: ACPI_IS_ALIGNED(address, reg->bit_width)
For your case, what the values of "address/access_width" are?
Can it be fixed by:
1. Either removing ACPI_IS_ALIGNED(address, reg->bit_width), or
2. moving the entire check out of if (!reg->access_width) to form:
if (!reg->bit_offset && reg->bit_width &&
ACPI_IS_POWER_OF_TWO(reg->bit_width) &&
ACPI_IS_ALIGNED(reg->bit_width, 8) &&
ACPI_IS_ALIGNED(address, reg->bit_width)) {
return (reg->bit_width);
} else if (reg->access_width) {
return (1 << (reg->access_width + 2));
} else {
if (reg->space_id == ACPI_ADR_SPACE_SYSTEM_IO) {
return (32);
} else {
return (max_bit_width);
}
}
Thanks

[Lv Zheng]
There might be GAS defined with AccessWidth = 0.
And its BitOffset can still make senses.
That's why I put the check here, making it a tuning rather than a regression safe check.
Thanks for the information, I'll submit the fix of the address check.
To convert it to:
ACPI_IS_ALIGNED(address, reg->bit_width / 8)
This is my fault.
Thanks

[Lv Zheng]
Your solution could result in problems like:
If a GAS is defined with bit_width not a power of 2, and access_width is any (0).
So the correct fix here is to make sure if bit_width is exactly 8,16,32,64, which matches old register descriptors.
I added address check here because I want to limit this regression safe check to old register descriptors.
As since the old bit_width can actually reflect the register's access width, the address of the register should always be aligned.
There might be cases that using the new GAS register descriptor format, it is possible to define a GAS that is not aligned, and it's bit_width is exactly 8,16,32,64.
We shouldn't make a default access_width decision using bit_width here.
The address check here can help to avoid applying this workaround on such cases.
Thanks and best regards

True. But OTOH switching to 32-bit accesses may result in us suddenly
trying to touch bytes we haven't accessed before.
