* [edk2-platforms PATCH 1/1] Platforms/RPi3: DisplayDxe virtual resolution improvements @ 2019-09-27 9:20 Pete Batard 2019-09-27 16:38 ` [edk2-devel] " Philippe Mathieu-Daudé 2019-09-28 23:05 ` Leif Lindholm 0 siblings, 2 replies; 12+ messages in thread From: Pete Batard @ 2019-09-27 9:20 UTC (permalink / raw) To: devel; +Cc: ard.biesheuvel, leif.lindholm From: Andrei Warkentin <andrey.warkentin@gmail.com> The Pi GPU decouples requested resolution from actual physical resolution and can perform scaling of virtual resolutions. This enables platform users to do something like ask for 1024x768 and get a framebuffer of that size, regardless of the actual output (which could be a very blurry SDTV). Specifically, this patch allows selecting which specific virtual resolutions to enable, thus replacing the old all-or-nothing behaviour with either all virtual resolutions supported, or just the native one. This patch also adds enables the common 7" Pi (800x480) screen to be used at 800x600 resolution, instead of forcing 640x480 as the only usable resolution.

What tag should I use? edk2-platforms master should always build against edk2 - if it does not, that's a bug. But I can't see any issues when building rpi3 with the current master branches. Any platform that is not willing to commit to this state of things can live on stable- or devel- branches in the edk-platforms repository. This process is described in https://github.com/tianocore/edk2-platforms/blob/about/Readme.md But please provide some more information than "I get errors". It is a much better use of maintainer time than sending me off verifying that something I expected to work still works (for me). > > Signed-off-by: Pete Batard <pete@akeo.ie> > > Hmm shouldn't this patch have a S-o-b from Andrei Warkentin too? No. Andrei is the author, he is not the person upstreaming. And the From: tag retains his authorship. Adding a S-o-b in that situation equates to putting in the commit message that "Oh, and Andrei says he's cool with https://developercertificate.org/".

Yeah, I recall this from the early days of moving from OpenPlatformPkg (symlink or submodule) to edk2-platforms (and PACKAGES_PATH). Something in the "let's avoid getting namespace clashes" logic goes bonkers[1] when you get any part of path overlap (i.e. Platform/ in more than one PACKAGES_PATH directory) ... but only when using edk2/ as WORKSPACE. [1] does what Leif wouldn't have expected > Anyhow I'll adapt my setup and not use edk2/ as $WORKSPACE anymore.

What tag should I use? I just re-built against very latest edk2/edk2-platforms/edk2-non-osi (pulled a couple minutes ago) and I'm not seeing any issue. It should build against latest.

We discussed this before with Leif (who has since replied), and agreed that it makes no sense to use a S-o-b unless it's the actual person sending the e-mail.

I am basically OK with this patch, but I note that the change in variable name/content means existing users will end up with stale variables. So I wonder if it would be worth explicitly adding a stanza deleting the old variable if found? / Leif. > Signed-off-by: Pete Batard <pete@akeo.ie> > --- > Platform/RaspberryPi/RPi3/Drivers/ConfigDxe/ConfigDxe.c | 9 +-- > Platform/RaspberryPi/RPi3/Drivers/ConfigDxe/ConfigDxe.inf | 2 +- > Platform/RaspberryPi/RPi3/Drivers/ConfigDxe/ConfigDxeHii.uni | 17 +++-- > Platform/RaspberryPi/RPi3/Drivers/ConfigDxe/ConfigDxeHii.vfr | 71 ++++++++++++++++---- > Platform/RaspberryPi/RPi3/Drivers/DisplayDxe/DisplayDxe.c | 53 +++++++++++++-- > Platform/RaspberryPi/RPi3/Drivers/DisplayDxe/DisplayDxe.inf | 2 +- > Platform/RaspberryPi/RPi3/RPi3.dec | 2 +- > Platform/RaspberryPi/RPi3/RPi3.dsc | 2 +- > 8 files changed, 125 insertions(+), 33 deletions(-) > > diff --git a/Platform/RaspberryPi/RPi3/Drivers/ConfigDxe/ConfigDxe.c b/Platform/RaspberryPi/RPi3/Drivers/ConfigDxe/ConfigDxe.c > index fcb4ce6935b6..98e58a560ed4 100644 > --- a/Platform/RaspberryPi/RPi3/Drivers/ConfigDxe/ConfigDxe.c > +++ b/Platform/RaspberryPi/RPi3/Drivers/ConfigDxe/ConfigDxe.c > @@ -92,6 +92,7 @@ SetupVariables ( > ) > { > UINTN Size;

That would be a valid point *if* the Pi 3 was using actual NVRAM storage to write those variables. However, we have no such thing on the hardware, so we currently store those variables on the SD card, within the firmware file itself. Which means, the minute you "install" a new firmware (by replacing the existing RPI_EFI.fd on your SD card with a new one), you're losing all your existing variables anyway, including stale ones. Maybe with the Pi 4 and its 512 KB EEPROM, we'll be able to look into preserving the variables. Or we may also look into writing variables to a separate virtual NVRAM file on the SD card, instead of just reusing the .fd (which we are doing for convenience). But for our current model, what you highlight is a non issue, as the only "upgrade" path forces users to always start with a virtual NVRAM that has been reset and that is therefore free from any stale variable.

Slightly too late nit: " ... also ..." suggest the 7" display forced to 800x600 change could have go in a separate patch. >>> >>> I am basically OK with this patch, but I note that the change in >>> variable name/content means existing users will end up with stale >>> variables. >>> >>> So I wonder if it would be worth explicitly adding a stanza deleting >>> the old variable if found? >> >> That would be a valid point *if* the Pi 3 was using actual NVRAM storage to >> write those variables. >> >> However, we have no such thing on the hardware, so we currently store those >> variables on the SD card, within the firmware file itself. >> >> Which means, the minute you "install" a new firmware (by replacing the >> existing RPI_EFI.fd on your SD card with a new one), you're losing all your >> existing variables anyway, including stale ones. > > Ah.
