gpu_mem not effective when not placed in config.txt but included extraconfig.txt #1332

Open gvolt opened 4 years ago

gvolt commented 4 years ago

Describe the bug

As stated in the documentation (https://www.raspberrypi.org/documentation/configuration/config-txt/misc.md) the include option "Causes the content of the specified file to be inserted into the current file.".

This currently does not work for the gpu_mem* options: Setting gpu_mem not in /boot/config.txt but in a file that is "linked" by the include option in /boot/config.txt has no effect.

To reproduce

  1. Remove any gpu_mem* settings from /boot/config.txt.
  2. Add include extraconfig.txt to /boot/config.txt.
  3. Create /boot/extraconfig.txt.
  4. Add gpu_mem=32 to /boot/extraconfig.txt.

Expected behaviour GPU memory should be set to the value given by the gpu_mem option in the file referenced by the include option in /boot/config.txt.

In the example GPU memory should be: 32MB

Actual behaviour The gpu_mem setting is not obeyed if it is placed in a file that is referenced by the include option in /boot/config.txt.

In the example on a RPi3B+ vcgencmg get_mem gpu shows a GPU memory of 76MB instead of 32MB.

Additional context The issue has been mentioned some time ago for Alpine Linux (look for keyword "Update 3"): https://www.raspberrypi.org/forums/viewtopic.php?f=56&t=60569&p=765924&hilit=gpu_mem+config.txt+include#p764210

timg236 commented 4 years ago

Include directives are not supported in the second stage bootloader on either Pi3 or Pi4

pelwell commented 4 years ago

To expand a bit on @timg236's comment, the gpu_mem setting is used by bootcode.bin (on Pi 3 and earlier) and by the SPI EEPROM (Pi 4) to determine where to load the main start*.elf firmware to. The config parsing done at that time is a restricted version of the full parser and is missing the include feature.

gvolt commented 4 years ago

Thank you very much for your very fast replies.

Is there any other possibility to set gpu_mem from outside config.txt?

pelwell commented 4 years ago

The answer is likely to be "No", but a bit of background on your use case would help.

gvolt commented 4 years ago

The question originally arose on a Volumio (audio player) system whose system updates overwrite the config.txt. The config.txt provided by Volumio already contains an include option pointing to a file called userconfig.txt. Its purpose is to give the user the ability to save customized boot configuration parameters to a file that does not get overwritten on system updates. After first discovering the issue regarding gpu_mem on that kind of system I tested on the Stretch based Rasbian system to verify.

Out of interest: When (on what bootloader) does the include option get processed?

pelwell commented 4 years ago

include is only expanded by the main firmware, i.e. start*.elf.

gvolt commented 4 years ago

Good to know.

Is there a list which of the options from the documentation do / don't work when placed in an included file?

pelwell commented 4 years ago

The following are supported by bootcode.bin (and probably the EEPROM as well):

  1. These settings: 
    gpu_mem
gpu_mem_256
gpu_mem_512
gpu_mem_1024
total_mem
require_total_mem
startx
start_x
start_debug
boot_partition
legacy_mapping
bootcode_delay
force_pvt
uart_2ndstage
start_file
fixup_file
  2. Filtering my model ([pi3])
  3. Filtering by serial number
  4. Filtering by gpio levels ([gpio4=0])

Of those, only the filters are supported by the main firmware, so they are the only ones which will work in an included file (plus all of the other config settings).

timg236 commented 4 years ago

Force_pvt and legacy_mapping aren't supported in the EEPROM but the others are. The Pi4 bootloader should probably have a dedicated page for config.txt, Something to do next time I update https://www.raspberrypi.org/documentation/hardware/raspberrypi/bcm2711_bootloader_config.md

gvolt commented 4 years ago

Ok, that's very helpful to know. Thanks a lot!

Regarding the options from the list above (and especially gpu_mem) would there be another way to achieve the same result like setting them in config.txt (well, I know that's what config.txt is for...)?

pelwell commented 4 years ago

would there be another way to achieve the same result like setting them in config.txt (well, I know that's what config.txt is for...)?

No, sorry. Would putting the user configuration options in the included file work (after some user retraining), or is there another case where the user setting comes from the restricted list above? It feels like there shouldn't be - they are all very low-level settings.

gvolt commented 4 years ago

In my case the users would not have to edit system files manually. They can install a plugin to the Volumio system which allows them to adjust e.g. the setting for gpu_mem through a GUI.

The plugin can easily work on the config.txt, but settings put in there would be overwritten each time the system gets updated whereas the included file does not get touched. So the plan was to use the include option for gpu_mem (amongst others but not from the listed ones). If there would be another way to set gpu_mem in the boot process this would / should also be handled not directly by the user who only accesses the GUI.

pelwell commented 4 years ago

The various "official" update methods - apt, rpi-update - never overwrite config.txt. You only get a new one by installing a new image.

Can the Volumio devs not be encouraged to put "system" settings in an included file that they are free to overwrite as they wish? Or split the file with a recognised separator so that user settings are preserved by an update?

gvolt commented 4 years ago

Yes, system updates come as new images ;)

It might be worth a tought to flip the concept where "vanillla" settings brought by system updates are being placed. I will put that up for discussion.

Appreciate your help and thoughts very much.
