Thanks for the patch. Two meta-suggestions:

(1) we should do one of the following:

(1a) Create a new BZ for this issue, cross-link it -- via the See Also
field -- with TianoCore#2174, and reference the new BZ in this commit
message. If we file this new BZ, it should get the Regression keyword.

(1b) Or else we should reopen TianoCore#2174, and reference *that* BZ in
this commit message.

(2) Independently of (1), the commit message should carry the following tag:

Fixes: 9c20342eed70ec99ec50cd73cb81804299f05403

Regarding this patch, the above updates only affect the commit message,
so I'm not asking for a v2 -- you can implement the commit message
changes right before pushing.

Thanks!
Laszlo

I would also mention that there are some bizzare code in EDK2 that

ArmVirtPkg/Library/ArmVirtDxeHobLib/HobLib.c
This is a very special case.

Please see the justification in commit ad90df8ac018
("ArmPlatformPkg/ArmVirtualizationPkg: Add private HobLib implementation
for DXE phase", 2014-09-18).

The stock HobLib instance depends on DebugLib, for using the normal
ASSERT() macro.

Furthermore, the stock serial-based DebugLib instance depends on
SerialPortLib, for printing messages.

That produces a HobLib -> DebugLib -> SerialPortLib dependency chain.

But, in case of this particular platform, our SerialPortLib instance
depends on HobLib, for retrieving the particulars of the serial port.
This creates a dependency cycle:

HobLib -> DebugLib -> SerialPortLib -> HobLib

which makes the platform un-buildable.

We had to break the dependency cycle somewhere, and the best (or maybe
only -- I don't recall exactly anymore) link to break was the HobLib ->
DebugLib dependency. We introduced our own HobLib instance, which (IIRC)
was almost identical to the stock one, except that its (only) DebugLib
dependency, namely the ASSERT(), was reimplemented with a plain
CpuDeadLoop(). And so the dependency chain ended up as:

DebugLib -> SerialPortLib -> HobLib

Not circular any more.

and OvmfPkg/Library/XenConsoleSerialPortLib/XenConsoleSerialPortLib.c)
Very similar same case; here we even have a comment:

//
// We can't use DebugLib due to a constructor dependency cycle between DebugLib
// and ourselves.
//

The BaseDebugLibSerialPort instance depends on SerialPortLib, so a
SerialPortLib instance cannot "depend back" on DebugLib, in combination
with BaseDebugLibSerialPort.
There's an additional problem in EDK2 that we never fixed, which is
the fact that constructor dependencies are not transitive across
library implementations that don't have a constructor themselves. For
instance, in the following case

LibA (+)
depends on
LibB (-)
depends on
LibC (+)

where (+) means 'has constructor' and (-) means 'has no constructor',
the EDK2 build tools may emit the LibA and LibC constructor
invocations in any order. However, as soon as you try to fix this, we
end up with circular dependencies all over the place, and none of the
platforms can be built anymore.
Yes, I've been aware of this; I've thought about it for a few minutes
just the other day. I was considering yet another "dynamic PCD setter"
NULL-class library instance, to be linked into various DXE modules.
Given the above problem, I figured if I ever started work on said lib
instance, I'd probably give it an empty CONSTRUCTOR -- not because that
function would have to do anything, but because the lib instance would
likely depend on other libraries, and *those* lib instances might have
important CONSTRUCTORs. And I wouldn't want this new lib instance to
break the dependency chain in the middle.

So in practice, all new lib instances seem to need CONSTRUCTORs now
(even if they are empty), just to avoid the problem you mention. And if
there is a build failure (circular dependency), try to deal with that on
a case by case basis.

(I admit that I didn't remember that we had tried fixing the problem in
BaseTools, and given up because of a multitude of sudden circular
dependencies! Thanks for the reminder!)

Thanks!

On 04/01/20 00:54, Sean via Groups.Io wrote:
I agree that safeintlib is not doing anything too interesting in this case but that's not really the point.  The argument for it is that it becomes the central point of code to check for safe conversions and an indicator that the developer was thoughtful about this conversion and didn't just cast to avoid the compiler complaining.  If everyone starts putting their own checks in place it leads to more code reviews, diversity in solutions, and opportunities for bugs.  All that said those are soft reasons for the change and that is up to you.

@Laszlo - On the ASSERT part, I have a different view point and am more curious about yours.  For release builds, I don't want to see CpuDeadLoops anywhere unless I am ok with the device being returned/refunded.  Our error path would be to exit the function with an error code and potentially log a ReportStatusCode.   I don't think you should continue in an invalid state as that just makes resolving the bug much much harder.    Given that the system can boot to at least a menu without this driver, it seems that failing out of the function would provide a better "RELEASE" experience.
Good points!

(1) There is a big difference between physical firmware and virtual
firmware. Similar difference between physical hardware and virtual
hardware. With virtualization, the "return/refund" case maps to "fix
OVMF, or fix QEMU". In particular the "fix QEMU" part is important,
because the assertion failure would show that QEMU is really broken, and
needs fixing. Thankfully, QEMU is fixable, and in that case, it *should*
be fixed; the "return/refund" path is both the right one, and not as
painful as with physical devices.

To exaggerate your point a bit, I would agree that ASSERT()s have no
place in space-craft software! :)

(2) I have actually considered -- at length -- returning an error code
from this function, instead of the failed assert / CpuDeadLoop(). The
error code from this function would be propagated out through the ext
scsi PassThru method. For that reason, I reviewed the error codes
defined for that protocol member function in the UEFI spec. All error
codes except EFI_TIMEOUT claim that "the SCSI operation was not sent /
not executed", therefore they do not apply in this case -- per spec, we
could only return EFI_TIMEOUT in case we fail to understand the PVSCSI
device model's response (because the device breaks "data sheet
compliance"). While I do think EFI_TIMEOUT is a *good* error code in
this case ultimately -- it shows that we simply can't tell whatever
happened on the device's side --, I figured (given point (1)) it would
be a very unwelcome complication for the code. Because upon returning
EFI_TIMEOUT, we also have to set HostAdapterStatus / TargetStatus to
something sensible (i.e., "fake"), and SenseDataLength to zero. Doable,
but didn't seem worth the churn.

(3) In RHEL OVMF packages, I exclusively ship DEBUG builds. For two
reasons: (a) many places in edk2 core code still use ASSERT() in place
of run-of-the-mill error checking (unfortunately), i.e., not explicit
"if"s; (b) bugs in software are the norm, not the exception, therefore
IMO debugging features should be an unalienable part of every software
package ever shipped to users. (If I could by my consumer electronics /
gadgets with full debug code enabled, I would, too.) When a RHEL user
reports an error, I don't want to start every one of my analyses with
the question, "can you please reproduce this with a debug build first".

I'm aware that debug code has additional cost (larger code size, perhaps
more CPU cycles spent, which is especially important on mobile devices,
yes). In my use case, the slowdown is not egregious -- first, most of
the boot time impact due to DEBUGs can be attributed to QEMU IO port
accesses, and that port is dynamically configurable (disabled by
default), so if it's not enabled, there's virtually no impact; second,
there don't seem to be insanely costly invariant checks built into OVMF
for the DEBUG target either. So I'm consciously committed to shipping
DEBUG only, and I admit that it does bias my thinking about RELEASE --
not that I'm against RELEASE *in general* for edk2, or ignoring RELEASE
willfully, it's just that I likely have blind spots wrt. RELEASE builds.


Finally, given that this is contained in OVMF I am fine with whatever makes the most sense for your platform and usecase.
Thanks a lot for confirming! In this case I'll go ahead with this patch.

Thanks!

Previous to this change, PvScsiFreeRings() was not undoing all
operations that was done by PvScsiInitRings().
This is because PvScsiInitRings() was both preparing rings (Allocate
memory and map it for device DMA) and setup the rings against device by
issueing a device command. While PvScsiFreeRings() only unmaps the rings
and free their memory.

Driver do not have a functional error as it makes sure to reset device
before every call site to PvScsiFreeRings(). However, this is not
intuitive.

Therefore, prefer to refactor the setup of the ring against device to a
separate function than PvScsiInitRings().

The memory map of an SOC is fixed in hardware. it doesn't change with
platform that uses SOC. So, there is no need to keep PCDs for these values
and we can use macros for these in SOC header file.

Any Platform using the SOC, can make use of the SOC header file.

Re: [PATCH v2 11/28] Silicon/NXP: remove not needed components

From: Pankaj Bansal <pankaj.bansal@...>

The structures elements and functions that are not necessary for booting
for now are being deleted.
Once the directory structure has been changed (i.e. we have clear
distinction between chassis code and header files and SOC code and header
files), we will put back the code and
structure components back at their appropriate respective place.

Also right now all the elements are being defined in structures, which are
not being used right now. So to simplify the code restructuring, I have
removed those for now. When we need to use those elements, we can define
those one by one.

[PATCH v2] ShellPkg: Fix 'ping' command Ip4 receive flow.

Maciej Rabeda
 

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3D2032

'ping' command's receive flow utilizes a single Rx token which it
attempts to reuse before recycling the previously received packet.
This causes a situation where under ICMP traffic,
Ping6OnEchoReplyReceived() function will receive an already
recycled packet with EFI_SUCCESS token status and finally
dereference invalid pointers from RxData structure.

The Soc info being printed can be removed from SOC lib.
We are in the process of implementing PEI Phase.
After PEI phase impelmentation this info would be printed in
implementation
common PEIM based on the information retrieved from PPIs.
e.g. gArmMpCoreInfoPpiGuid can be used to print cluser and
cluster
core info.

Re: [PATCH v2 08/28] Silicon/NXP/LS1043A: Use BaseSerialPortLib16550 as SerialPortLib

UART Programming model in LS1043A is compatible with PC16550D.
Therefore, BaseSerialPortLib16550 can be used instead of our own
implementation of SerialPortLib.

(If the need for SerialUartClockLib goes away, that line can be

I requested after the initial submission that you "either follow the
manual git setup steps from
https://github.com/tianocore/tianocore.github.io/wiki/Laszlo%27s-unkempt-git-guide-for-edk2-contributors-and-maintainers
or execute edk2/BaseTools/Scripts/SetupGit.py in each of the tianocore
repositories"

Now, neither appears to have happened, as .c still comes before .inf
and paths are still truncated.

But in addition to that, we realised that git happily ignores settings
for --stat. So, please, execute aforementioned script, but then
generate v3 with --stat=1000 --stat-graph-width=20.

For this particular patch, the side discussion on the edk2 portion may
make it redundant, so I'm deferring review.

References: <20200327215536.9556-1-michael.kubacki@...>

Please let me know if you have suggestions. I'll look into it more.
(1) *Normally*, here's what I would tell you:

Please log in to your groups.io account, and navigate to the following
setting:

Your name (upper right corner)
Account
Preferences (top of left sidebar)
I always want copies of my own emails (checkbox at the bottom)

Please *untick* this checkbox.

The name of the checkbox is very misleading. The actual behavior is the
following:

"I am a gmail user, and gmail de-duplicates messages that are sent to
me both directly, and reflected through the mailing list. As a
special case, the same de-duplication applies to messages I send to
the list, and are reflected to me by the list -- gmail just hides
those from me as "seen". I don't like this; I want my reflected
copies of messages that I sent. Because the de-duplication is
Message-ID based, groups.io should please falsify the Message-ID on
those messages that I send *AND* are delivered back to me *only*"

Meaning, if you have this box checked, then groups.io places
<....@groups.io>-style message IDs in the emails that it sends back *to
you* (only to you) *and* that originate from you.


(2) *However*, that is not the problem here. (Or, more precisely, not
the only problem.) Because, as I say above, this message-ID
re-generation by groups.io only applies to *you*; so the threading of
your patch series would only be broken in *your* list folder, not in
mine (or in any other list subscriber's).

But, the threading *is* broken on my end too.

And the reason for that is that the SMTP server that you use, ignores
the Message-ID put in place by git-send-email, and generates its own.

Your original message ID (as stated above), from git-send-email, is:

20200327215536.9556-1-michael.kubacki@...

But the message ID in my list folder is:

MWHPR07MB3440A69B5AFAD0E373974FBFE9CC0@...

Therefore, the original message-id (from git-send-email) is not moved to
the X-Microsoft-Original-Message-ID header by groups.io -- instead, it
is moved there by your SMTP server, at <outlook.com>.

Can you disable that somehow? It is incorrect behavior. An SMTP server
itself should only put a Message-ID on an outgoing email if that email
doesn't already come with one.

To summarize, there are two issues:

(a) your groups.io account settings have the gmail-oriented Message-ID
falsification enabled, which breaks threading for you (and only for you)

(b) your SMTP server overwrites the git-send-email-generated Message-ID
with its own, which breaks threading for every list subscriber
(including you).

You can easily remedy (a) in your groups.io account settings. Not sure
how you can fix problem (b) -- can you use a different SMTP server
maybe?

(I've been very happy that we've finally seen patches posted to the list
from a @microsoft.com email address -- it would be fantastic if that
continued, with the threading fixed even!)

Thanks!

Re: [PATCH] Features/Intel/UserInterface: Add VirtualKeyboardFeaturePkg

Ni, Ray
 

Ming,
1. Can you update all the "TODO" in Readme.md to fill with detailed information?
2. gEfiTouchPanelGuid contains the 'Efi' prefix but isn't defined in UEFI or PI spec. Can you please rename it to "gEdkiiTouchPanelGuid"?
Because there is no header file associated with this GUID, the rename without changing the GUID value may have no impact to other code.
3. Can you please evaluate all the debug messages controlled by DEBUG_VK_* macro? Can some debug messages be removed? Can the proper
debug error level (ERROR, WARN, INFO, VERBOSE) be assigned to the remaining debug messages?
I would like to remove all the DEBUG_VK_* macros.

4. Can you please check whether the code can pass ECC check?

Thanks,
Ray

+# Overview

+* **Feature Name:** Virtual Keyboard

+* **PI Phase(s) Supported:** DXE

+* **SMM Required?** No

+

+## Purpose

+# High-Level Theory of Operation

+This driver will use the following protocol:

+ gEfiAbsolutePointerProtocolGuid

+ gEfiTouchPanelGuid

+ gEfiGraphicsOutputProtocolGuid

+

+It will show a picture like a keyboard in the graphic output, then detect

+position when user touch the touch panel, then calculate the key which the

+user want to type.

+

+

+This is particularly useful for features that use custom build tools or require non-standard tool configuration. If the

+standard flow in the feature package template is used, this section may be empty.

+

+## Test Point Results

+*_TODO_*

+The test(s) that can verify porting is complete for the feature.

+

+Each feature must describe at least one test point to verify the feature is successful. If the test point is not

+implemented, this should be stated.

+

+## Functional Exit Criteria

+*_TODO_*

+The testable functionality for the feature.

+

+This section should provide an ordered list of criteria that a board integrator can reference to ensure the feature is

+functional on their board.

+

+## Feature Enabling Checklist

+*_TODO_*

+An ordered list of required activities to achieve desired functionality for the feature.

+

+## Performance Impact

+A general expectation for the impact on overall boot performance due to using this feature.

+

+This section is expected to provide guidance on:

+* How to estimate performance impact due to the feature

+* How to measure performance impact of the feature

+* How to manage performance impact of the feature

+

+## Common Optimizations

+*_TODO_*

+Common size or performance tuning options for this feature.

+

+This section is recommended but not required. If not used, the contents should be left empty.

Subject: [PATCH v1 1/1] INF Spec: Add file dependency to [Sources] syntax

From: Pierre Gondois <Pierre.Gondois@...>

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2464

When building an edk2 module, a C file was including a .hex file generated by the compilation of an ASL file.
To describe this dependency between an ASL file and a C file, the edk2 patch,
- named "BaseTools: Build ASL files before C files",
- discussed at: https://edk2.groups.io/g/devel/message/52550
has been created.
This patch allows to establish build dependencies in the [Sources] section, between files that are not of the same language.
E.g.:
[Sources]
FileName1.X
FileName2.Y : FileName1.X
FileName3.Z : FileName1.X FileName2.Y

Here:
* FileName1.X will be built prior to FileName2.Y.
* FileName1.X and FileName2.Y will be built prior to
FileName3.Z.

This patch updates the Inf specification accordingly.

I would also mention that there are some bizzare code in EDK2 that

ArmVirtPkg/Library/ArmVirtDxeHobLib/HobLib.c
This is a very special case.

Please see the justification in commit ad90df8ac018
("ArmPlatformPkg/ArmVirtualizationPkg: Add private HobLib implementation
for DXE phase", 2014-09-18).

The stock HobLib instance depends on DebugLib, for using the normal
ASSERT() macro.

Furthermore, the stock serial-based DebugLib instance depends on
SerialPortLib, for printing messages.

That produces a HobLib -> DebugLib -> SerialPortLib dependency chain.

But, in case of this particular platform, our SerialPortLib instance
depends on HobLib, for retrieving the particulars of the serial port.
This creates a dependency cycle:

HobLib -> DebugLib -> SerialPortLib -> HobLib

which makes the platform un-buildable.

We had to break the dependency cycle somewhere, and the best (or maybe
only -- I don't recall exactly anymore) link to break was the HobLib ->
DebugLib dependency. We introduced our own HobLib instance, which (IIRC)
was almost identical to the stock one, except that its (only) DebugLib
dependency, namely the ASSERT(), was reimplemented with a plain
CpuDeadLoop(). And so the dependency chain ended up as:

DebugLib -> SerialPortLib -> HobLib

Not circular any more.

and OvmfPkg/Library/XenConsoleSerialPortLib/XenConsoleSerialPortLib.c)
Very similar same case; here we even have a comment:

//
// We can't use DebugLib due to a constructor dependency cycle between DebugLib
// and ourselves.
//

The BaseDebugLibSerialPort instance depends on SerialPortLib, so a
SerialPortLib instance cannot "depend back" on DebugLib, in combination
with BaseDebugLibSerialPort.
There's an additional problem in EDK2 that we never fixed, which is
the fact that constructor dependencies are not transitive across
library implementations that don't have a constructor themselves. For
instance, in the following case

LibA (+)
depends on
LibB (-)
depends on
LibC (+)

where (+) means 'has constructor' and (-) means 'has no constructor',
the EDK2 build tools may emit the LibA and LibC constructor
invocations in any order. However, as soon as you try to fix this, we
end up with circular dependencies all over the place, and none of the
platforms can be built anymore.
