++Garbage collect fbdev scrolling acceleration |
47 |
++-------------------------------------------- |
48 |
++ |
49 |
++Scroll acceleration is disabled in fbcon by hard-wiring p->scrollmode = |
50 |
++SCROLL_REDRAW. There's a ton of code this will allow us to remove: |
51 |
++- lots of code in fbcon.c |
52 |
++- a bunch of the hooks in fbcon_ops, maybe the remaining hooks could be called |
53 |
++ directly instead of the function table (with a switch on p->rotate) |
54 |
++- fb_copyarea is unused after this, and can be deleted from all drivers |
55 |
++ |
56 |
++Note that not all acceleration code can be deleted, since clearing and cursor |
57 |
++support is still accelerated, which might be good candidates for further |
58 |
++deletion projects. |

+ This option enables UML's "hardware" random number generator. It |
864 |
+ attaches itself to the host's /dev/random, supplying as much entropy |
865 |
+ as the host has, rather than the small amount the UML gets from its |
866 |
+- own drivers. It registers itself as a standard hardware random number |
867 |
+- generator, major 10, minor 183, and the canonical device name is |
868 |
+- /dev/hwrng. |
869 |
+- The way to make use of this is to install the rng-tools package |
870 |
+- (check your distro, or download from |
871 |
+- http://sourceforge.net/projects/gkernel/). rngd periodically reads |
872 |
+- /dev/hwrng and injects the entropy into /dev/random. |
873 |
++ own drivers. It registers itself as a rng-core driver thus providing |
874 |
++ a device which is usually called /dev/hwrng. This hardware random |
875 |
++ number generator does feed into the kernel's random number generator |
876 |
++ entropy pool. |
