Re: ath0: unable to attach hardware
Hello, I hope you had a pleasant trip. Sorry for not replying for a while. Anyway, I tried to do what you asked me to. However, it seems like I misunderstood the handbook and/or your request, as I failed to compile the kernel. I copied my previous, working kernel config to a new file, and commented the devices ath, ath_pci, ath_hal and ath_rate_sample, as well as the options AH_SUPPORT_AR5416, AH_DEBUG and ATH_DEBUG. I did this because I could not find instructions in the handbook that explained how to build a module as a kld, and commenting the modules out was my best guess. Please point me to the relevant section in the handbook in the case that the information was actually there and I just was unable to find it.

Re: [RFC] proposed 'lem' patch to improve behaviour under emulation
LOL, it's ironic, my intention in creating lem was to isolate the old pre-PCIE driver from active changes so as to assure it's stability... but virtualization comes around to bit me in the butt :) I guess I'm agreeable in principle with what you're doing Luigi, but can you do me a favor and hold off until I'm technically back from vacation (after the new year) and let me review the code then?

The cross-dso requirement would explain why my simpler approaches to reproduce it didn't work. But for me there's no difference between RC2 and release (FreeBSD clang version 3.2 (tags/RELEASE_32/final 170710) 20121221), both cause my applications to crash.

I've seen what I think is the same thing due to a miscompilation of unwind-dw2.c that caused crashes related to cross-shared-object exception handling. It seems to have been fixed with the 3.2 release but I haven't tested it too thoroughly yet. -Nathan ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"

clang 3.2 RC2 miscompiles libgcc?
Hi,
I noticed that most of my C++ applications in recent versions of FreeBSD
head suddenly crash without me recompiling them. I tracked it down to
r243830 which imported a new clang version. The new clang seems to
compile libgcc in a wrong or at least incompatible way with what gcc
expects. In fact, the breakage only occurs with libgcc compiled by a
post-r243830 clang and an application compiled with g++ -O2. For me, the
crash happens with boost::program_options, but I'm not sure if that is
necessary for the crash.
$ cat po.cc
#include
int main(void) {
namespace po = boost::program_options;
const char *argv[] = { "a.out", "-x", 0 };
po::options_description options("Options");
options.add_options()("bla", "");
try {
po::variables_map vm;
po::store(po::parse_command_line(2, argv, options), vm);
notify(vm);
return 0;
} catch (const std::exception &ex) {
return 1;
}
}

[RFC] proposed 'lem' patch to improve behaviour under emulation
This patch implements two features for the 'lem' driver that
greatly improve the throughput under proper hypervisor.
This is joint work with Vincenzo Maffione and Giuseppe Lettieri,
I am posting it here for review, will then commit it
if there are no objections.
The first change is to implement a sysctl to access the 'itr'
interrupt moderation register for the devices supported by this
driver. It is little more than adding a struct into the device
descriptor, and one line to create the dynamic sysctl entry, same
as it is done for the other mitigation registers.
The second change is more interesting and has huge benefits on througput.
Under virtualization, "VM exits" (which happen every time there is
an access to a register of the emulated peripheral) are extremely
expensive. In the tx path of the 'lem' driver, there is a write
to the TDT register on every packet sent.
The patch we propose, if enabled through a sysctl (defaults off,
so no change from current behaviour) defers writes to the TDT
register when there is a pending transmit interrupt.
This means that, together with proper emulation of interrupt
mitigation on the hypervisor side, the number of VM exits
is dramatically reduced. To give you an idea, on a modern
system with qemu-kvm and companion patches, UDP throughput is
KVM QEMU
standard KVM, standard driver20 Kpps 6.3 Kpps
modified KVM, standard driver37 Kpps28 Kpps
modified KVM, modified driver 200 Kpps34 Kpps
As you can see, on kvm this change gives a 5x speedup to the tx path,
which combines nicely with the 2x speedup that comes from supporting
interrupt mitigation alone in the hypervisor. Without kvm (or kqemu ?)
the benefits are much lower, as the guest becomes too slow.
Patch follows. It would be good if people with real hardware
using the 'lem' driver could test it to make sure it does no
harm on their devices (in any case the sysctl variable
dev.em.0.mit_enable must be set to explicitly enable it
at runtime).
(for those curious to test it under kvm, i am also attaching a
patch that you need to apply to qemu in order to exploit the
effect of interrupt mitigation; it is a followup of a similar
patch i posted in july to the qemu mailing list, and i will
post it the update there as well, shortly. Unfortunately
we do not have kvm on freebsd..)
cheers
