ACPICA version 20140828 released
by Moore, Robert
28 August 2014. Summary of changes for version 20140828:
This release is available at https://acpica.org/downloads
1) ACPICA kernel-resident subsystem:
Fixed a problem related to the internal use of the Timer() operator where a 64-bit divide could cause an attempted link to a double-precision math library. This divide is not actually necessary, so the code was restructured to eliminate it. Lv Zheng.
ACPI 5.1: Added support for the runtime validation of the _DSD package (similar to the iASL support).
ACPI 5.1/Headers: Added support for the GICC affinity subtable to the SRAT table. Hanjun Guo <hanjun.guo(a)linaro.org>.
Example Code and Data Size: These are the sizes for the OS-independent acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The debug version of the code includes the debug output trace mechanism and has a much larger code and data size.
Current Release:
Non-Debug Version: 98.8K Code, 27.3K Data, 126.1K Total
Debug Version: 192.1K Code, 79.8K Data, 271.9K Total
Previous Release:
Non-Debug Version: 98.7K Code, 27.3K Data, 126.0K Total1
Debug Version: 192.0K Code, 79.7K Data, 271.7K Total
2) iASL Compiler/Disassembler and Tools:
AcpiExec: Fixed a problem on unix systems where the original terminal state was not always properly restored upon exit. Seen when using the -v option. ACPICA BZ 1104.
iASL: Fixed a problem with the validation of the ranges/length within the Memory24 resource descriptor. There was a boundary condition when the range was equal to the (length -1) caused by the fact that these values are defined in 256-byte blocks, not bytes. ACPICA BZ 1098
Disassembler: Fixed a problem with the GpioInt descriptor interrupt polarity flags. The flags are actually 2 bits, not 1, and the "ActiveBoth" keyword is now supported properly.
ACPI 5.1: Added the GICC affinity subtable to the SRAT table. Supported in the disassembler, data table compiler, and table template generator.
iASL: Added a requirement for Device() objects that one of either a _HID or _ADR must exist within the scope of a Device, as per the ACPI specification. Remove a similar requirement that was incorrectly in place for the _DSD object.
iASL: Added error detection for illegal named references within control methods that would cause runtime failures. Now trapped as errors are: 1) References to objects within a non-parent control method. 2) Forward references (within a method) -- for control methods, AML interpreters use a one-pass parse of control methods. ACPICA BZ 1008.
iASL: Added error checking for dependencies related to the _PSx power methods. ACPICA BZ 1029.
1) For _PS0, one of these must exist within the same scope: _PS1, _PS2, _PS3.
2) For _PS1, _PS2, and PS3: A _PS0 object must exist within the same scope.
iASL and table compiler: Cleanup miscellaneous memory leaks by fully deploying the existing object and string caches and adding new caches for the table compiler.
iASL: Split the huge parser source file into multiple subfiles to improve manageability. Generation now requires the M4 macro preprocessor, which is part of the Bison distribution on both unix and windows platforms.
AcpiSrc: Fixed and removed all extraneous warnings generated during entire ACPICA source code scan and/or conversion.

In my reply, I only talked about 4 mapping entries which doesn't exceed the current number of early ioremap slot.
Was it better to offer early_ioremap_debug log to prove that we really need to increase it?
And to prove that all of the mappings are done by the code already upstreamed?

Could you send a tested patch to linux-acpi(a)vger.kermel.org for this?
I think the number of early mapping slots need to be increased by 1 because of this case.

Re: [Devel] kernel boot fail with efi earlyprintk (bisected)
by Zheng, Lv
Hi,
I checked the arch/x86/platform/efi/early_printk.c.
In early_efi_scroll_up(), 2 mapping entries will be used for the src/dst screen buffer.
In drivers/acpi/acpica/tbutils.c, we've improved the early table loading code in acpi_tb_parse_root_table().
We now need 2 mapping entries:
1. One mapping entry is used for RSDT table mapping. Each RSDT entry contains an address for another ACPI table.
2. For each entry in RSDP, we need another mapping entry to map the table to perform necessary check/override before installing it.
When acpi_tb_parse_root_table() prints something through EFI earlyprintk console, we'll have 4 mapping entries used.
The current 4 slots setting of early_ioremap() seems to be too small for such a use case.
I'm not 100% sure if this is the cause.
If it's the cause and we think both of the mappings are reasonable, we can simply increase the FIX_BITMAPS_SLOTS defined in arch/x86/include/asm/fixmap.h.
What do you think of this?
Thanks and best regards

Re: [Devel] kernel boot fail with efi earlyprintk (bisected)
by Zheng, Lv
Hi,
There is only limited entries in the x86 early mapping which is implemented by the FIXMAP.
So this means for all __init call invoked for x86, if there was a early mapping in it, it should be unmapped before exiting the __init call.
Using this rule, all __init call implementers can make sure that before entering the __init call, the limited number of FIXMAP entries is enough.
The following bisected commit just increase early mapping times from 1 to 2 in ACPICA early table handling code.
The number of 2 is less than the number of available FIXMAP entries.
And ACPICA code has ensured that all mappings are correctly unmapped after the table initialization.
So we didn't break the rule.
We can offer a workaround in ACPICA to reduce mapping count from 2 to 1 using a global option.
But since this report sounds like that the root cause is earlyprintk=efi has broken the above rule and the existing issue is triggered by this cleanup.
So could someone check the earlyprintk=efi code first?
I think earlyprintk=efi should either unmap the increased mapping or increase the number of FIXMAP entries in case earlyprintk=efi need additional early mappings.
Otherwise it will always be chances for earlyprintk=efi to break future code.
Thanks and best regards

Patch to override "Creator ID" and "Creator Revision"
by Neel Natu
Hi,
The following patch allows the "Creator ID" and "Creator Revision" to
be overridden at compile time.
At the moment the "Creator Revision" is a stand-in for the compiler
version which implies that the tables change every time the compiler
version changes. This patch decouples "Creator Revision" from the
compiler version.
It would be great if this could be committed.
best
Neel
