<wens>
chances are you have the wrong settings for the debug uart base address
<rellla>
you mean UART0 or UART1?
barbarin has quit [Ping timeout: 272 seconds]
<wens>
yes, but those option only affect the default value for the base address
<rellla>
wens: hm. CONFIG_DEBUG_KERNEL, CONFIG_DEBUG_LL, CONFIG_EARLY_PRINTK are set
<rellla>
CONFIG_DEBUG_SUNXI_UART0 and CONFIG_DEBUG_SUNXI_UART1 don't work

<rellla>
how do i get the right values?
<wens>
you can copy the values associated with CONFIG_DEBUG_SUNXI_UART*
<rellla>
wens: works now. default 0xf1c28000 if DEBUG_SUNXI_UART0 and default 0x01c28000 if DEBUG_SUNXI_UART0
<rellla>
i wonder how this values can be set automatically with make menuconfig ...

anyone encounter an issue where your device worked as a wifi hotspot regardless of the feature being turned on? The settings also didn't affect the password or the SSID name either.

I've seen the issue on 3 different A20 devices... all different manufacturers. I'm wondering if there's an issue with the AW SDK.

hello, what is the sunxi-next branch for?
<quitte>
hmm. "DMAengine driver handles slave DMA clients..." what is master DMA and is it already supported on A20?
_massi has quit [Ping timeout: 240 seconds]
<quitte>
Turl: does the above imply that there is mainline support for DMA already? for example for sata or gmac ?
<Turl>
quitte: master is when the device does the DMA
<Turl>
pretty sure that mmc for example does that
<Turl>
maybe sata too, not sure
<quitte>
Turl: thanks. I was hoping that didn't exist on ARM devices. It means that those devices can change RAM content without OS oversight, doesn't it?
<Turl>
I'm not completely sure on how it works or if it goes through the MMU
<Turl>
quitte: but that's a safe assumption I guess
<Turl>
quitte: what's your worry?
<quitte>
Turl: A couple of years ago it turned out that on apple devices the firewire port could be used to change the ram content with no way to prevent that except disabling thgat port entirely
<quitte>
since then i generally dislike the fact that peripherals have to be trusted
<Turl>
quitte: pretty sure that happens today still
<quitte>
exactly
<Turl>
with thunderbolt
<quitte>
I was hoping that the iommu introduced with amd64 would change that
<quitte>
but it didn't
<Turl>
quitte: still, I don't see how that can be a problem with eg. mmc
<Turl>
you'd need to request a read and provide an address from the OS side in order to do anything
<quitte>
in the case of mmc it's probably fine. you only have to trust the controller, not the card. pci-e and pci however ...
<Turl>
yeah
<Turl>
but we don't have PCIe so it's moot :)
<quitte>
kind of. would be nice to have memory protection for hardware,too. it's just as buggy as software so shouldn't be trusted to only write where it is supposed to, either
<quitte>
Do you happen to know if an iommu could even do what i'd think it does?
<Turl>
I have no idea about iommus, sorry :(

quitte: you can use an IOMMU to limit the memory your device is going to DMA to/from.
<quitte>
maz: so the translation part is just for the whole memory region and not per peripheral?
barbarin has quit [Quit: ChatZilla 0.9.91.1 [Firefox 34.0/20141127111547]]
<maz>
quitte: that depends on the IOMMU. the ARM SMMU can have per-device contexts, each one getting its own set of page tables.
<quitte>
I have never heard of SMMU. is that something that comes with a cortex-a core or is it a peripheral? Does the i.MX6 have it?
<maz>
quitte: no idea about imx. it is a peripheral that comes between your memory and your devices, controlled by the CPU. basically an IOMMU. look at the ARM infocenter for details about the architecture.
<quitte>
maz: thanks.
