Simon Gerber [Mon, 14 Oct 2013 14:27:33 +0000]
Added a short-term solution for making gem5 harness tests work.

Due to changing the default armv7 platform in hake/Config.hs.template to
pandaboard the gem5 harness tests stopped working. This commit fixes this by
introducing a new build target (release_gem5) for scalebench. The longer-term
solution would probably be to make Config.hs variables configurable from
harness machines.

6 years agoarmv7: Unified global interrupt controller code.
Simon Gerber [Mon, 14 Oct 2013 09:40:04 +0000]
armv7: Unified global interrupt controller code.

The initialization code for the pl130 global interrupt controller was
duplicated for the arm_gem5 and omap44xx ARMv7 platforms.  This led to bugs
being fixed in one version but not the other. I've now moved all the
controller-specific code to kernel/arch/armv7/gic.c and only left the mapping
and initializing of the GIC registers in the platform-specific code.

6 years agokernel: Fixed paging_map_memory() in ARM-based architectures to work for all arguments.
Simon Gerber [Fri, 11 Oct 2013 13:11:02 +0000]
kernel: Fixed paging_map_memory() in ARM-based architectures to work for all arguments.

The problem was that for some reason paging_map_memory() was rounding down the
size (in bytes) of the region to map to the next multiple of SECTION_BYTES and
then wouldn't map the last section whenever the value of bytes was a multiple
of SECTION_BYTES already.

Thanks to Jeremia Bär and Ralf Sager (AOS students) for alerting us to the
problem.

6 years agoRedesigned hw page table dumping to be an invocation on a dispatcher cap.
Simon Gerber [Wed, 2 Oct 2013 13:03:00 +0000]
Redesigned hw page table dumping to be an invocation on a dispatcher cap.

This has two benefits over the old design where dumping hw page tables was a
kernel cap invocation and took a dispatcher cap as an argument:
1) This is probably the most common use case, you don't have to go through
   the monitor if you just want to dump your own hw page tables.
2) A domain which has the dispatcher cap of another domain (mostly because
   it's going to spawn said domain) can dump the hw page tables of the
   to-be-spawned domain without capability address contortions.

6 years agoMove scope of hub to outer level.
Gerd Zellweger [Tue, 24 Sep 2013 14:40:04 +0000]
Move scope of hub to outer level.

altough it is used there. Leads to problems when compiling with -Wall.

7 years agoEnable unaligned memory access on ARMv7.
Gerd Zellweger [Wed, 4 Sep 2013 13:47:58 +0000]
Enable unaligned memory access on ARMv7.

Some ARM platform are sensitive to unaligned memory access.

To parse the FAT boot-sector we read certain two-byte values
at unaligned offsets. The underlying Mackerel code uses a
uint16_t pointer to do that, which results in a fault.

On ARMv7 we can just enable unaligned memory access in CP15.
Another way around this would be to declare the pointer as
__packed__. However, this is only supported by ARMs official
compiler suite.

Claudio Föllmi [Thu, 5 Sep 2013 01:00:06 +0000]
fixed hake naming of temporary directories

when compiling libraries, hake creates temporary directories for each library.
these used to be only named after the library.
this lead to race conditions when compiling for several architectures, as they
would all use the same directory name, and overwrite/delete each others data.
I added the name of the architecture into the directory name, so different
architectures will work in different temp directories.

timer interrupts enabled

fixed interrupt handler writing to trap area for non-trap interrupts
enabled timer interrupts at reasonable intervals (reasonable for -O2 and no caches)
added system call for restoring a context (just for armv7-m, replacing a x86-specific interrupt),
because the ONLY way to restore an IT block is by exiting handler mode (there is literally no other mechanism)
(will only be called if userspace tries to restore a context that was saved by the kernel, and comes from interrupting an IT block or a ldm/stm instruction)

You may want to use -O2 from now on (because we use interrupts, and thrashing is possible)
The compiler we use will probably complain up to 3 times ("unable to find a register to spill in class 'GENERAL_REGS'")
just retry the faulting compile instruction with -O1, and then restart make

7 years agokernel: omap44xx: support for booting the 2nd core
Kornilios Kourtis [Fri, 16 Aug 2013 16:27:50 +0000]
kernel: omap44xx: support for booting the 2nd core

 - disabled print locks because they seem to lead to a deadlock
 - monitor on 2nd core starts, but it gets blocked on a
   request_ramfs_serv_iref() call

If you want to play around, you might find the following patch to
initiate starting the 2nd core from memtest useful:

monitor: cleanup code for booting cores on ARMv7

The code should have the same semantics as before, except that it does
not use ram_set_affinity() to make sure that the kernel  image is placed
on the first 2G, because this does not seem to work. Instead, a simple
frame_alloc() is used for now.

These are currently dummy capabilities, as the only ARM platform for
