Normally this bench has read all data to one large buffer and
than written it back to the drive but for SATA 3 (6 Gbps) benchmarks
we would need a buffer of approximately 1.2 GB to do it this way
and reach 2 seconds bench time. Thus we use a buffer of SATA request size
and override it with every request.
This commit splits the Fiasco.OC-specific extension for the cli_monitor
into one for the Arndale platform, and one for all others. On Arndale
we add the cpu_frequency command beside the ones defined on all platforms.
Initialize and limit port speed to 3 Gbps in general because the Seagate
Barracuda 1TB throws much errors with 6 Gbps by now.
Try all port speeds from the highest to the lowest as long as debouncing fails
and try them all again in this order when falling back to slower debouncing.
Try to recover from all types of interface error.
When a port was recovered from an error during a NCQ command
get the last LBA that was accessed successfully and continue command from
this point.
Use a platform driver through the 'Regulator' service to do CMU and PMU config.
Switch off verbosity by default.
To raise expressiveness of the benchmark it dynamically adjusts the
transfer amount at any test to get a result that was measured
over a transfer time of 2000 ms at least and 2300 ms at a max.
* Retry debouncing first with a higher trial time and if this also doesn't
work with lower link speed additionaly.
* Ignore DevSlp feature because it isn't needed anyway as far as i can see.
* Relax some restrictions according the feedback of the drive as far as it
seem to have no effect in Linux too
Fix#753
The verbosity must be enabled at two levels: at compile time
via an enum that switches the availability of verbosity code
and via two members of 'Mmio' named '_read_verbose' and
'_write_verbose'. The latter are initialized to 0 (change this to
enable verbosity globally) and can be used to locally enable
(or disable) verbosity in deriving classes.
Ref #753
Currently, on the Arndale platform, core uses a different thread context
area base address than the other tasks (0x20000000 vs. 0x40000000). This
is problematic, because core calculates the location of the UTCB area of a
new thread relatively to core's own thread context area base. So, the UTCB
area of non-core threads ends up in a virtual address range which is
outside of the task's thread context area and not marked as used in the
task's RM session.
With this patch, the same thread context area base address gets used in
core and in the other tasks.
Fixes#779.
Added spec file for ARM-VFPv3 floating-point unit. This shadows
'base/include/arm/' with 'base/include/arm/vfp' and enables a 'memcpy_cpu'
version that mainly uses the FPU. Enabled VFP support for 'foc_arndale'.
Ref #773
* Implements platform driver for Arndale providing Regulator for CPU clock
* Implements a cpu frequency scaling test using the affinity test
* Fixes#770
TFTP server requiring absolute directory names are supported (better) -
specify in RUN_OPT "--tftp-absolute" to create Pulsar config with absolute
path names for PXE boot.
Additional a symbolic link is created from the build directory to
"$PXE_TFTP_DIR_BASE$PXE_TFTP_DIR_OFFSET" automatically. This eases the use
together with autopilot for x86.
Commit c464ee2e6673fe328a8717342dca30f3b0204cb8 removed the RX_BUF_SIZE from
the NIC session interface. Mistakenly, the nic_loopback server was missed
when doing this change.
The PWD variable contains the current working directory of the original
location where 'make -C' is executed, not the directory specified as
argument of '-C'. The tools referenced by ports/libports, however,
expect PWD to point to the root of the respective repository.
This patch splits the download of signatures from the download of the
archive to improve robustness. This way, signature files will be
downloaded even if the corresponding archive is already in place.
