Recent Linux versions refuse to print actual virtual kernel addresses,
|
|
|
16fb238 |
to not give a hint about the location of the kernel in a randomized virtual
|
|
|
16fb238 |
address space. This affects the output of the sunxi MMC controller
|
|
|
16fb238 |
driver, which now produces the rather uninformative line:
|
|
|
16fb238 |
|
|
|
16fb238 |
[ 1.482660] sunxi-mmc 1c0f000.mmc: base:0x(____ptrval____) irq:8
|
|
|
16fb238 |
|
|
|
16fb238 |
Since the virtual base address is not really interesting in the first
|
|
|
16fb238 |
place, let's just drop this value. The same applies to Linux' notion of
|
|
|
16fb238 |
the interrupt number, which is independent from the GIC SPI number.
|
|
|
16fb238 |
We have the physical address as part of the DT node name, which is way
|
|
|
16fb238 |
more useful for debugging purposes.
|
|
|
16fb238 |
To keep a success message in the driver, we make this purpose explicit
|
|
|
16fb238 |
with the word "initialized", plus print some information that is not too
|
|
|
16fb238 |
obvious and that we learned while probing the device:
|
|
|
16fb238 |
the maximum request size and whether it uses the new timing mode.
|
|
|
16fb238 |
So the output turns into:
|
|
|
16fb238 |
[ 1.750626] sunxi-mmc 1c0f000.mmc: initialized, max. request size: 16384 KB, uses new timings mode
|
|
|
16fb238 |
[ 1.786699] sunxi-mmc 1c11000.mmc: initialized, max. request size: 2048 KB
