to make it possible to mark the bootscreen framebuffer as write combining in early initialization, mtrr() is changed not not to error() but to return an error string. as bootscreen() is used before multiprocessor initialization, we have to synchronize the mtrr's for every processor as it comes online. for this, a new mtrrsync() function is provided that is called from cpuidentify() if mtrr support is indicated. the boot processor runs mtrrsync() which snarfs the registers. later, mtrrsync() is run again from the application processors which apply the values from the boot processor. checkmtrr() from mp.c was removed as its task is also done by mtrrsync() now. |
