Various "see your local kernel hacker" #118

Closed ghost closed 5 years ago

ghost commented 5 years ago

When booting, many messages asking to "see [my] local kernel hacker" appear:

vgapci0: child drmn0 requested pci_enable_io vgapci0: child drmn0 requested pci_enable_io [drm] Unable to create a private tmpfs mount, hugepage support will be disabled(-19). __pm_runtime_resume not implemented -- see your local kernel hacker Failed to add WC MTRR for [0xe0000000-0xefffffff]: -22; performance may suffer [drm] Got stolen memory base rxdbe00000, size 0x4000000 [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).

After many normal lines, I also get the following lines:

get_nr_swap_pages not implemented -- see your local kernel hacker current_is_kswapd not implemented -- see your local kernel hacker

The line "Failed to add WC MTRR for [0xe0000000-0xefffffff]: -22; performance may suffer" has already been discussed in https://github.com/FreeBSDDesktop/kms-drm/issues/58 .

In spite of all these messages, everything seems to work fine.

I also see those messages since a couple of days.

I also noticed that I'm not able to run the game "Enemy Territory" in fullscreen... maybe it's related ?

valpackett commented 5 years ago

No, these messages are not related to anything. Unimplemented (mostly power management related) functions in the kernel driver are very unlikely to impact fullscreen ability of applications.

This have been muted in release versions.
