Hi, on my UX31A it is/was like this: - after 277959 the display was dark - backing out 277959 gave full brightness, but no brightness control using hw.acpi.video.lcd0.brightness anymore - after some more syncing with Linux 3.5.7, brightness control using hw.acpi.video.lcd0.brightness works again - brightness control using the function keys (acpi_asus_wmi?) never really worked, neither before nor after the changes to drm2/i915.

Re: Fwd: UMA initialization failure with 48 core ARM64

I have been trying out different values given to uma_prealloc() and uma_zone_reserve(). It started working when I increased the parameter in uma_prealloc() 32 times and left uma_zone_reserve() as it was originally. UMA_BOOT_PAGES also needs to be set to 512. Thank you very much for your help. Do you know how the value to uma_prealloc() should scale with the number of CPUs? If it is not obvious, then maybe for now we should make a #define with a value to multiply BT_MAXALLOC by, with a comment that a higher number is required on platforms with many CPUs. What do you think the final fix should look like? I suspect it is not only the number of CPUs which makes the play. Note that the number of tags is already scaled with the number of CPUs. It is also the question of how much the given architecture needs to allocate before the normal uma/vmem mechanisms start working. My quess is that arm64 performes more kva_alloc()s on early stages than other architectures. I am forwarding the result of my conversation with Konstantin Belousov. With his help I was able to boot 48 cores on an arm64 platform. I needed to set UMA_BOOT_PAGES=512 and increase the parameter given to uma_prealloc() in vmem_startup() 32 times (giving 32 * BT_MAXALLOC). It looks like this should be made configurable to avoid running out of space for initial allocations on some platforms. In our case, the panic happened still in SI_SUB_VM sysinit.

Strictly speaking MAX_INT is indeed the upper limit, but the number is so big it's not a limit in practice and it's not going to be in foreseeable future.
