This is new and but required when for DM_VIDEO conversion. video-uclass has a common way to flush video via video_sync so the driver has to trigger this flush and without this, the vidconsole shows inconsistent characters.

DM_VIDEO, take from the relocation - VIDEO_SIZE if I remember based on MAX video size. Then there is always a logic to inject in the simple_framebuffer dts the information for reserved memory. The platform always defines MAX_SIZE of the video. so HDMI resolutions that does not fit the size are not handled. Rockchip is not completed on this implementation, I have sent a patch some time ago but I was struggling to have a working persistent framebuffer Michael > > > > > > static bool sunxi_has_hdmi(void) > > > { > > > #ifdef CONFIG_VIDEO_HDMI > > > @@ -1052,9 +1064,11 @@ static enum sunxi_monitor sunxi_get_default_mon(bool allow_hdmi) > > > return sunxi_monitor_none;

An enum is used for variables that can hold multiple values. There's no relationship between those values, you cannot use the BPP in place of the width there for example, it doesn't make any sense. So you must not use an enum. > > > -ulong board_get_usable_ram_top(ulong total_size) > > > -{ > > > - return gd->ram_top - CONFIG_SUNXI_MAX_FB_SIZE; > > > -} > > > - > > > > I couldn't find how you're allocating and reserving the video buffer now > > for simplefb to use later on. > > Based on maximum supporting resolutions and bpp as explained above and > similar like what sunxi_de2 and other platforms like rockchip. via > plat->size. It really doesn't explain how you're allocating and reserving it for simplefb though, merely how much memory you're allocating. Let me rephrase this. simplefb will run in Linux based on an address that is passed from the bootloader to Linux through the device tree. How do you make sure that Linux will not reuse that buffer for something else once it's been booted? The previous code was doing that by removing enough space from the total memory available, so Linux could run only on the total amount of RAM minus the size of the framebuffer. You removed that, so how does it work now? And if you're changing that somehow, at the very least, it should be either in a separate patch or mentionned in the commit log. > > > > > static bool sunxi_has_hdmi(void) > > > { > > > #ifdef CONFIG_VIDEO_HDMI > > > @@ -1052,9 +1064,11 @@ static enum sunxi_monitor sunxi_get_default_mon(bool allow_hdmi) > > > return sunxi_monitor_none;

I agree that an enum does not make sense here. That seems to be copied from sunxi_de2.c, which has the same code ;-) My guess is this stems from some misunderstood "use enums instead of #define!" recommendation.

You removed that, so how does it work > now? So the former code lowered U-Boot's perception of gd->ram_top, but sunxi-de2 doesn't do this either. I don't think this on its own is a real problem. What both sunxi-de2 and this patch do is to patch the /memory node in the DT to exclude the framebuffer region, at the same time when patching in the framebuffer details into the chosen node (in the last function of this patch, not in this email anymore). There *is* a bug in this patch that creates a small overlap, which makes Linux crash. That's easily fixed, though: start = gd->bd->bi_dram[0].start; - size = gd->bd->bi_dram[0].size - sunxi_display->fb_size; + size = sunxi_display->fb_addr - start; ret = fdt_fixup_memory_banks(blob, &start, &size, 1); Maxime, does that answer your concerns? I tested this (fixed) patch with simplefb, and it works: the /memory node ends 32MB before the end of DRAM, and the framebuffer works in Linux. > And if you're changing that somehow, at the very least, it should be > either in a separate patch or mentionned in the commit log. > > > > > > > > static bool sunxi_has_hdmi(void) > > > > { > > > > #ifdef CONFIG_VIDEO_HDMI > > > > @@ -1052,9 +1064,11 @@ static enum sunxi_monitor sunxi_get_default_mon(bool allow_hdmi) > > > > return sunxi_monitor_none;

So this video_set_flush_dcache() does not *do* an actual cache_clean, it merely enables regular cache cleans in video-uclass.c:video_sync(). This replaces the automatic determination of CONFIG_VIDEO's cfb_do_flush_cache in cfb_console.c, with an explicit request. The initial cache clean of the framebuffer above is independent of this. sunxi_de2 does this video_set_flush_dcache() call as well. Cheers, Andre

DM_VIDEO migration deadline is already expired, but around 80 Allwinner boards are still using video in a legacy way. ===================== WARNING ====================== This board does not use CONFIG_DM_VIDEO Please update the board to use CONFIG_DM_VIDEO before the v2019.07 release. Failure to update by the deadline may result in board removal. See doc/driver-model/migration.rst for more info. ==================================================== So let's live these boards on the tree before the video maintainer removes it by converting in to DM_VIDEO. Tested in Bananapi M1+ Plus 1920x1200 HDMI out.
