6 years agoarmv7: use A9 timer functions only in pandaboard
Kornilios Kourtis [Tue, 20 May 2014 08:57:41 +0000]
armv7: use A9 timer functions only in pandaboard

These functions are only defined for pandaboard:
 collect2: ld terminated with signal 11 [Segmentation fault]
 ./armv7/kernel/arch/armv7/syscall.o: In function `sys_syscall':

Gerd Zellweger [Sun, 27 Apr 2014 21:24:13 +0000]
Support for Intel I210 Ethernet card in e1000.

Makes networking work on our vacherin machine.

Right now this is another card type in e1000, however, it may be the same as
82576 card but at least, juding from the code we have for 82576 some of the
init code has to be different.

Also, change e1000 to select first card found instead of last, usually
first card has function 0x0 so we will choose the right one for machines
with only one cable. Better would probably be to try them all and see
where we get a link.

6 years agocp15: use clean & invalidate instead of clean only
Sebastian Wicki [Wed, 5 Feb 2014 22:21:24 +0000]
cp15: use clean & invalidate instead of clean only

The current implementation of cp15_invalidate_d_cache() only cleans
the cache, which means that dirty cache lines are written back to
memory. However, cache lines which were modified in memory, for
example by a DMA engine, are not re-read.

This change uses the clean & invalidate operation, which means that
the cache lines are cleaned and invalidated: All dirty cache lines
are written back to memory, all other other cache lines are marked
as invalid until they are re-read from memory.

6 years agoAdded benchmarks for the SDMA driver
Sebastian Wicki [Tue, 4 Feb 2014 23:33:52 +0000]
Added benchmarks for the SDMA driver

The code /usr/bench/sdma_bench performs and measures multiple
transfer requests. It optionally spawns a number of worker in
order to simulate multiple clients and uses distributed
barriers to synchronize all these workers.

The benchmark in /usr/bench/bulk_sdma implements a simple bulk
transfer framework for test purposes. The different implementations
either perform the copy themselves in software, or offload them to
the SDMA driver.

6 years agoAdded basic support for the Cortex A9 Global Timer
Sebastian Wicki [Tue, 4 Feb 2014 23:11:20 +0000]
Added basic support for the Cortex A9 Global Timer

The Cortex A9 global timer is a 64-bit incrementing counter, which
is memory mapped in the private memory region. Thus, the code for
the timer is currently all in the CPU driver.

To read out the timer in userspace, two system calls are needed,
one for the lower and and one for the upper half of the counter.
The following helper function is provided to correctly read out
the timer value in two 32 bit reads as suggested in the ARM TRM:

  errval_t sys_debug_hardware_global_timer_read(uint64_t *ret)
