Different platform builds of ROS include different drivers. So if you used MC7355 on a MIPSBE or ARM device, it doesn’t mean x86 build will include those drivers as well.
is this still repeatable in v7? if yes - please contact support with supout.rif file.
information here is not all correct. Modems should be supported on all systems equally.
X86 installation is still supported.
Perhaps somebody will actually dig out reference to the claim by @Larsa.
[edit] I see that @antonsb claims this is not true. However, there were many forum threads by users with problems with unsupported hardware, ranging from unsupported disk drives (e.g. SATA disks) to unsupported NICs (virtually all 10Gbps NICs fall into this category) and including support only for 32-bit installs (which imposes 2GB RAM limitation) and every time some MT staffer said that users should install CHR to overcome the problems. So in reality, x86 installs were not supported in the last 5 years (or more) even though officially x86 was not discontinued.
Traditional VM hypervisors didn’t expose hardware directly to VMs, they provided pseudo hardware instead (e.g. virtio net NIC or IDE virtual disks) so CHR only needs to support those few virtual types of hardware. Recently VM hypervisors indeed started to support HW pass-through meaning VMs will have to support such hardware natively. With v7 there are better chances to see support for relatively recent hardware, with v6 this was lost case long ago due to hopelessly outdated kernel used (and I guess this was primary reason for practical discontinuation of support for bare-metal x86 / x64 installations).
And I suspect that the future answer will be “don’t use pass-through”
My laptop is old though, nothing recent about it.. Two mPCIe ports and two other ports that I’m not using (one is another mPCIe, do not remember the fourth’s form factor right now).. MC7355 is from 2012.. It had a MC7455 but it died a few years ago, so I put the MC7355 back.. Yes, it is time to look for a replacement, but I’m picky.. haha
Well, if that’s true I stand corrected but my advice is to update the wiki/help pages about what versions or Ros and hardware (on bare metal) that are still supported.
And in general the success rate is probably much higher using CHR rather than bare metal installation even on a laptop.
Regarding pass-though you won’t notice the difference on a single instance.
For ROS v6 anything built around components newer than around 10 years is “new”. Which includes mPCIe … and OS needs some drivers to work with mPCIe bus, not sure if older PCI drivers support it.
v7 seems to have defaulted to x86-64 after the update. Showing
Free Memory: 15.5 GiB
Total Memory: 15.6 GiB
v6 was definitely 2GB RAM though.
It is odd though, System-Resources-Hardware has two options.. Multi CPU and Allow x86-64. Multi CPU is enabled, Allow x86-64 is not, yet RouterOS is still showing 16 GB RAM.
