All,
The new EDKII Platform Boot Manager protocol provides a platform hook to solve below problem.
Can you please review and think about:
1. Is it a proper solution to the problem?
2. Is the new protocol/function name proper?
3. Are the parameters in the function proper?
**Problem:
Platform requires certain BlockIo/SimpleFileSystem/LoadFile instances don't cause Boot#### created. It's a need of platform customization.
**Details:
Boot#### for BlockIo/SimpleFileSystem/LoadFile are created by API EfiBootMangerRefreshAllBootOptions(). There are 2 places that call this API:
1. Platform Boot Manager calls the API (usually in the full configuration boot path)
2. UiApp calls the API when entering "Boot Manager" page and "Boot Maintenance Manager" page.
Platform can change Platform Boot Manager library to remove the unneeded Boot#### in case #1.
But platform has no way to remove the Boot#### created in case #2 .
Thanks,
Ray

1. Is it a proper solution to the problem?
Yes, it already solved my concern discussed in the other email.
2. Is the new protocol/function name proper?
Yes, but I'm not good at naming. We may need others' feedback. :)
3. Are the parameters in the function proper?
How about we only have two parameters as below to simplify this code change?
typedef
EFI_STATUS
(EFIAPI *REFRESH_ALL_BOOT_OPTIONS) (
IN OUT EFI_BOOT_MANAGER_LOAD_OPTION **BootOptions,
IN OUT UINTN *BootOptionsCount,
);
In addition, I have one more suggestion about the structure name inline.
Besides these two comments, everything else looks good to me.
Regards,
Sunny Wang

Platform can change Platform Boot Manager library to remove the unneeded Boot#### in case #1.
But platform has no way to remove the Boot#### created in case #2 .

For being consistent with other EDKII protocols like EDKII_PLATFORM_LOGO_PROTOCOL , how about we update it to the following?

Hi Sunny,
I thought about keeping the arguments the way you suggested but then decided against it so that the auto enumerated boot options list is not tampered with in case the function implementation hits an error in between. This way, if the function returns an error, we can use the list we passed in and continue boot.
I am OK with any suggested name changes.
Thanks
Ashish

Subject: RE: [edk2-devel] [PATCH v4] MdeModulePkg: Add EDK2 Platform Boot Manager Protocol
External email: Use caution opening links or attachments
1. Is it a proper solution to the problem?
Yes, it already solved my concern discussed in the other email.
2. Is the new protocol/function name proper?
Yes, but I'm not good at naming. We may need others' feedback. :) 3. Are the parameters in the function proper?
How about we only have two parameters as below to simplify this code change?
typedef
EFI_STATUS
(EFIAPI *REFRESH_ALL_BOOT_OPTIONS) (
IN OUT EFI_BOOT_MANAGER_LOAD_OPTION **BootOptions,
IN OUT UINTN *BootOptionsCount,
);
In addition, I have one more suggestion about the structure name inline.
Besides these two comments, everything else looks good to me.
Regards,
Sunny Wang

Subject: Re: [edk2-devel] [PATCH v4] MdeModulePkg: Add EDK2 Platform Boot Manager Protocol
All,
The new EDKII Platform Boot Manager protocol provides a platform hook to solve below problem.
Can you please review and think about:
1. Is it a proper solution to the problem?
2. Is the new protocol/function name proper?
3. Are the parameters in the function proper?
**Problem:
Platform requires certain BlockIo/SimpleFileSystem/LoadFile instances don't cause Boot#### created. It's a need of platform customization.
**Details:
Boot#### for BlockIo/SimpleFileSystem/LoadFile are created by API EfiBootMangerRefreshAllBootOptions(). There are 2 places that call this API:
1. Platform Boot Manager calls the API (usually in the full configuration boot path)
2. UiApp calls the API when entering "Boot Manager" page and "Boot Maintenance Manager" page.
Platform can change Platform Boot Manager library to remove the unneeded Boot#### in case #1.
But platform has no way to remove the Boot#### created in case #2 .
Thanks,
Ray

Good point. The way you used is more robust. It can cover a mistake in function's error handling. Thanks for clarifying this, Ashish.
In addition, the other naming suggestion just comes to mind. How about we rename the function to a more generic one (based on location) like AfterEnumerateBootOptions or a more specific one like RefreshEnumeratedBootOptions? In the future, we may add the other hook function in the EfiBootManagerRefreshAllBootOption to deal with the boot options that are not created by BmEnumerateBootOptions. In this case (two hook functions in EfiBootManagerRefreshAllBootOption), the original function name "RefreshAllBootOptions" may cause some confusion.
Regards,
Sunny Wang

Hi Sunny,
I thought about keeping the arguments the way you suggested but then decided against it so that the auto enumerated boot options list is not tampered with in case the function implementation hits an error in between. This way, if the function returns an error, we can use the list we passed in and continue boot.
I am OK with any suggested name changes.
Thanks
Ashish

External email: Use caution opening links or attachments
1. Is it a proper solution to the problem?
Yes, it already solved my concern discussed in the other email.
2. Is the new protocol/function name proper?
Yes, but I'm not good at naming. We may need others' feedback. :) 3. Are the parameters in the function proper?
How about we only have two parameters as below to simplify this code change?
typedef
EFI_STATUS
(EFIAPI *REFRESH_ALL_BOOT_OPTIONS) (
IN OUT EFI_BOOT_MANAGER_LOAD_OPTION **BootOptions,
IN OUT UINTN *BootOptionsCount,
);
In addition, I have one more suggestion about the structure name inline.
Besides these two comments, everything else looks good to me.
Regards,
Sunny Wang

Subject: Re: [edk2-devel] [PATCH v4] MdeModulePkg: Add EDK2 Platform Boot Manager Protocol
All,
The new EDKII Platform Boot Manager protocol provides a platform hook to solve below problem.
Can you please review and think about:
1. Is it a proper solution to the problem?
2. Is the new protocol/function name proper?
3. Are the parameters in the function proper?
**Problem:
Platform requires certain BlockIo/SimpleFileSystem/LoadFile instances don't cause Boot#### created. It's a need of platform customization.
**Details:
Boot#### for BlockIo/SimpleFileSystem/LoadFile are created by API EfiBootMangerRefreshAllBootOptions(). There are 2 places that call this API:
1. Platform Boot Manager calls the API (usually in the full configuration boot path)
2. UiApp calls the API when entering "Boot Manager" page and "Boot Maintenance Manager" page.
Platform can change Platform Boot Manager library to remove the unneeded Boot#### in case #1.
But platform has no way to remove the Boot#### created in case #2 .
Thanks,
Ray

Thanks for checking this, Ray. Platform may want to: 1. Refresh the static boot options (that are not created by BmEnumerateBootOptions) without a reboot. 2. Update some other static-informational data or configuration data right after calling EfiBootManagerRefreshAllBootOption. 3. Always skip calling EfiBootManagerRefreshAllBootOption for the cases like BOOT_ASSUMING_NO_CONFIGURATION_CHANGES. I know these actions can be done by adding code to other places, but using hooks in EfiBootManagerRefreshAllBootOption would be an easier solution for the platform. We won't need to take care of all the EfiBootManagerRefreshAllBootOption callers. Therefore, If we don't have a concern about adding more hooks and want to give the platform more flexibility, we could add two more hooks (1 and 3) in the future to have three hooks as below: 1. BeginOfRefreshAllBootOptions 2. RefreshAllBootOptions or RefreshEnumeratedBootOptions 3. EndOfRefreshAllBootOption By the way, the current change looks good enough to me. In case Ashish or others are in urgent need of this code change, we can discuss my comments later in a separated email.

Hi Sunny, For the 3 use cases you suggested, please let me know if you think I am wrong. 1. RefreshAllBootOptions can refresh boot options which are auto created by BmEnumerateBootOptions as well as NV boot options in the variable store. Platform implementation of RefreshAllBootOptions can have calls to platform specific other libraries/drivers that create more boot options. 2. In EfiBootManagerRefreshAllBootOption, BmEnumerateBootOptions is the only function that populates boot options and then validates/invalidates them as well as NV boot options. RefreshAllBootOptions can modify static-informational data or configuration data from the boot options created by BmEnumerateBootOptions as well as in NV store. 3. Solution for third use case can be derived by using a PCD which can be defaulted to tell code to call EfiBootManagerRefreshAllBootOption every time but can be overridden by platform to not call it from anywhere except BDS.

Platform may want to: 1. Refresh the static boot options (that are not created by BmEnumerateBootOptions) without a reboot. 2. Update some other static-informational data or configuration data right after calling EfiBootManagerRefreshAllBootOption. 3. Always skip calling EfiBootManagerRefreshAllBootOption for the cases like BOOT_ASSUMING_NO_CONFIGURATION_CHANGES. I know these actions can be done by adding code to other places, but using hooks in EfiBootManagerRefreshAllBootOption would be an easier solution for the platform. We won't need to take care of all the EfiBootManagerRefreshAllBootOption callers. Therefore, If we don't have a concern about adding more hooks and want to give the platform more flexibility, we could add two more hooks (1 and 3) in the future to have three hooks as below: 1. BeginOfRefreshAllBootOptions 2. RefreshAllBootOptions or RefreshEnumeratedBootOptions 3. EndOfRefreshAllBootOption By the way, the current change looks good enough to me. In case Ashish or others are in urgent need of this code change, we can discuss my comments later in a separated email.

Hi Ashish, I was busy with some other stuff and forgot to reply to you. Sorry about that. I was just thinking about adding more hooks would be easier for us to add platform code. However, it looks like your preference is to have only one hook. I'm also fine with this. Moreover, your solutions look workable to me. I will give them a try. Thanks!

RefreshAllBootOptions can refresh boot options which are auto created by BmEnumerateBootOptions as well as NV boot options in the variable store. Platform implementation of RefreshAllBootOptions can have calls to platform specific other libraries/drivers that create more boot options. 2. In EfiBootManagerRefreshAllBootOption, BmEnumerateBootOptions is the only function that populates boot options and then validates/invalidates them as well as NV boot options. RefreshAllBootOptions can modify static-informational data or configuration data from the boot options created by BmEnumerateBootOptions as well as in NV store. 3. Solution for third use case can be derived by using a PCD which can be defaulted to tell code to call EfiBootManagerRefreshAllBootOption every time but can be overridden by platform to not call it from anywhere except BDS.
