Please define a macro for define DEFAULT_COUNT_WIDTH 48 and change the
format like this:
if (of_property_read_u32(node, "count-width", _pmu.count_width))
csky_pmu.count_width = DEFAULT_COUNT_WIDTH;

I agree dma_alloc_wc is necessary, and we need add another more attribute
bit in PTE: _PAGE_BUF.
Perhaps using _PAGE_BUF + _PAGE_CACHE are better then _PAGE_CONHENCY.

LB translation in hardware and shadow page
tables is for stage 2 translation. Shadow page tables care vmid not
asid.
If hardware don't support H-extension (MMU 2-stages translation), it's
hard to accept for virtualization performance.
I don't think hypervisor is a real scene for GLOBAL in PTE.
Are there other scene for GLOBAL in PTE?
Best Regards
Guo Ren
very different, but
there are only 10 attribute-bits for riscv (In fact we've wasted two bits
to support huge RV32-pfn :P). So I think it is time to merge these two bits
before hardware supports GLOBAL. Reserve them for future!

Hi Christoph,
I use PFN_DOWN() every where as possible and seems it's a habit
problem. So let risc-v maintainer to choose "PFN_DOW()" or

Also the same with "end_of_DRAM & max_low_pfn".

The driver is for C-SKY SMP timer. It only support oneshot event
and 32bit overflow for clocksource. Per cpu core has one timer and
all timers share one clock-counter-input the same clocksource.
This use mfcr instructions to access the regs.

not give up our mother tongue. RISC-V is a great ISA, and it will
promote other ISAs to be more open.
From ecology, diversity will make Linux more robust.
We will continue to improve csky subsystem, and now is only the
beginning.
