They are re-branded (or cloned) by several different vendors. In particular the most serious seem to be:- VideoStrong (http://www.videostrong.com/product.asp?sid=257) Acemax (http://www.acemax.net.cn/droid-world/droid-box/hybrid-android-dvb-t2-dvb-s2/kii-pro-ki-plus-s2-t2-combo-149.html#.WRls_GjyiUk) I actually have an Xtreamer mxV (http://www.xtreamer.net/mxv) which seems to be an exact clone. My first question is what to put in the compatible line. I could put: a) compatible = "videostrong,kiplus", "acemax,kiplus", "xtreamer,mxv", "amlogic,meson-gxbb"; but there are many other KI PLUS vendors so I could maybe omit the vendor: b) compatible = "kiplus", "xtreamer,mxv", "amlogic,meson-gxbb"; but this poses the problem of what to put in amlogic.txt which seems to require a vendor. My second question is what to base my patch on: Should it be v4.12/dt64 in Kevin's linux-amlogic.git? My third question concerns the SDIO WiFi. The WiFi chip seems to vary between boards. My board has a Realtek RTL8189ETV. I note that its (unfortunately out of tree) driver is loaded even if the DT specifies a Broadcom chip. Is it really necessary to specify the chip in the DT? (It seems that the SDIO, like the PCI and USB buses, recognizes connected devices by their IDs.) My final question is how to submit my patch. Should I send an RFC to this list for approval before possibly spamming others? I thank you in advance for your replies and your tolerance.

Sorry, the generic is not really acceptable here since there is always a vendor, and adding a new vendor is easy and well accepted. The point with Amlogic based Set-Top-Boxes is that they are 99% based on a reference design given from Amlogic, and only the SBCs (Odroid-C*, Khadas, NanoPi K2) differs. Here is the list of Amlogic Reference Designs I am aware of : - S905 : P200 and P201 - S905X : P212 - S905D : P230 and P231 - S912 : Q200 and Q201 When pushing S905 based boxes, we were not really aware of that, but starting with S905X we started to base the board DTS on the Reference Design DTSI like the Khadas Vim and the Wetek Hub/Play2. I'm aware there is a lot of work to clean up all the other S905/S905X and S912 based boxes... but the majority of boxes should run unchanged with the reference design DTS. > >> >> My second question is what to base my patch on: >> Should it be v4.12/dt64 in Kevin's linux-amlogic.git?

The KI PLUS has GXBB (S905), Fast (100Mbs) Ethernet, 1 GiB RAM, four USB ports and often Realtek RTL8189ETV WiFi. The P20x boards are probably the closest but they have Gigabit Ethernet and the KI PLUS only has Fast Ethernet. (Indeed the stock uBoot prompt and some Linux boot messages contain the string "p20x".) So, although obviously derived from these reference designs as you say, Ethernet doesn't work with the P200 and P201 DTS. Obviously working Ethernet is essential. The only existing GXBB DTS with 1GiB RAM and Fast Ethernet is the GXBB version of the Nexbox A95x. But USB on the KI PLUS doesn't work with this DTS. So I really do need a new DTS.

In fact the P201 probably does have Fast Ethernet. I remember that my board used to work well with the P201 DTB. But this was with the Amlogic 3.14.y kernels. In the mainline 4.x kernels it was incorrectly described with Gigabit Ethernet. But I see that this has just been corrected in 4.12-rc1. However unfortunately I cannot get 4.12-rc1 to boot: I get no kernel output at all on the serial console :( I have never had any problems with the 4.10 and 4.11 series. Have you tried 4.12-rc1 on a GXBB board?

Well, in view of the above I probably can make do with the P201 DTS, at least until I try to get the internal DVB tuners working. ^ permalink raw reply [flat|nested] 8+ messages in thread

Would it be possible to mainline an Amlogic specific version of the defconfig which would only include modules relevant to Amlogic boards?
