[PATCH 2/3] xen: make direct versions of irq_enable/disable/save/restore to common code

[Jeremy Fitzhardinge]

Now that x86-64 has directly accessible percpu variables, it can also
implement the direct versions of these operations, which operate on a
vcpu_info structure directly embedded in the percpu area.

In fact, the 64-bit versions are more or less identical, and so can be
shared.  The only two differences are:
 1. xen_restore_fl_direct takes its argument in eax on 32-bit, and rdi on 64-bit.
    Unfortunately it isn't possible to directly refer to the 2nd lsb of rdi directly
    (as you can with %ah), so the code isn't quite as dense.
 2. check_events needs to variants to save different registers.

[PATCH 2/3] xen: make direct versions of irq_enable/disable/save/restore to common code

Now that x86-64 has directly accessible percpu variables, it can also
implement the direct versions of these operations, which operate on a
vcpu_info structure directly embedded in the percpu area.

In fact, the 64-bit versions are more or less identical, and so can be

 1. xen_restore_fl_direct takes its argument in eax on 32-bit, and rdi on 64-bit.
    Unfortunately it isn't possible to directly refer to the 2nd lsb of rdi directly
    (as you can with %ah), so the code isn't quite as dense.
 2. check_events needs to variants to save different registers.

btw., that's still worth fixing, plus the comments styles could be 
standardized. And this should grow an extra space after the comma:

        lea 4(%edi),%esp                /* point esp to new frame */

(there's 5-6 similar instructions in that file with this problem - the rest 
is fine.)

# df -h 

works fine.
SATA drive attached to Intel ICH9R (AHCI) detected at boot up

  Regardless ifconfig and "brctl show" reports seem to be good.
Local IP obtained via dhcp is 192.168.1.34 and /etc/init.d/networking restart
seems to release old IP and obtain new one pretty soon .
Xen Host is uncreachable on the LAN.
Attempt to ping 192.168.1.1 (ADSL Modem) fails with message :-
No IPV6 router present and vice-versa i cannot ping Xen Host
from the LAN.
Attempt to run:-
# startx
obviosly fails.

Re: Booting up the most recent 2.6.29-rc3 (pv_ops Dom0 support) under Xen Unstable on Intel SATA (AHCI) box

[Boris Derzhavets]

[-- Attachment #1.1: Type: text/plain, Size: 15662 bytes --]

 Due to ZYXEL P 660 RT2 is not IPV6 router i've tried to disable IPV6
on Ubuntu 8.10 Server.

1. Via blacklist
2. Just rebuilding kernel (worst option)

and IPV6 got disabled either way i choosed.

During the session i do can obtain new IP via 
# /etc/networking restart
report goes to screen nicely. Four DHCP commands as usual
However Dom0 doesn't really get on the LAN.
It keeps stay unpingable in both directions

# df -h 

works fine.
SATA drive attached to Intel ICH9R (AHCI) detected at boot up

  Regardless ifconfig and "brctl show" reports seem to be good.
Local IP obtained via dhcp is 192.168.1.34 and /etc/init.d/networking restart
seems to release old IP and obtain new one pretty soon .
Xen Host is uncreachable on the LAN.
Attempt to ping 192.168.1.1 (ADSL Modem) fails with message :-
No IPV6 router present and vice-versa i cannot ping Xen Host
from the LAN.
Attempt to run:-
# startx
obviosly fails.

Re: Booting up the most recent 2.6.29-rc3 (pv_ops Dom0 support) under Xen Unstable on Intel SATA (AHCI) box

[Boris Derzhavets]

[-- Attachment #1.1: Type: text/plain, Size: 16519 bytes --]

Build 2.6.29-rc3 with the most recent change set and load under Xen Unstable
Logged into Dom0.
Was able to load F10 PV DomU via prepared image.
DomU obtained  IP (192.168.1.38) via DHCP .
Opened ssh connection to Dom0 192.168.1.34 (Ubuntu 8.10 Server) 

LAN is still unavailable for both DomU & Dom0.

 Due to ZYXEL P 660 RT2 is not IPV6 router i've tried to disable IPV6
on Ubuntu 8.10 Server.

1. Via blacklist
2. Just rebuilding kernel (worst option)

and IPV6 got disabled either way i choosed.

During the session i do can obtain new IP via 
# /etc/networking restart
report goes to screen nicely. Four DHCP commands as usual
However Dom0 doesn't really get on the LAN.
It keeps stay unpingable in both directions

# df -h 

works fine.
SATA drive attached to Intel ICH9R (AHCI) detected at boot up

  Regardless ifconfig and "brctl show" reports seem to be good.
Local IP obtained via dhcp is 192.168.1.34 and /etc/init.d/networking restart
seems to release old IP and obtain new one pretty soon .
Xen Host is uncreachable on the LAN.
Attempt to ping 192.168.1.1 (ADSL Modem) fails with message :-
No IPV6 router present and vice-versa i cannot ping Xen Host
from the LAN.
Attempt to run:-
# startx
obviosly fails.

So you're saying that you got internal host<->guest networking going, 
but external networking fails.

What's your ethernet hardware?  Does it fail to probe, or does it probe 
but not work?

My board is  ASUS P5K Premium/WIFI.
Second Ethernet Adapter Realtek 8110SC (eth1) is attached to ADSL Modem (emulating local DHCP server for intranet ) and is working as xen bridge.

# ifconfig
# brctl show

looks fine,  just like under Xen 3.3.1 with xen-ified kernel

 Interface "eth1"  fails to work with LAN, but obtains IP address for Dom0 via DHCP request to ADSL Modem. I am able do DHCPRELEASE and DHCPREQUEST via "eth1"  whenever  i want. 
But,  i cannot ping IP of ADSL modem from Dom0 , which clearly shows up in  DHCPOFFER & DHCPACK responses.
 F10 DomU obtained IP via this bridge also with no problems and communicates via ssh with Dom0.

>Does it fail to probe, or does it probe but

Sorry,what exactly means "probe" eth1 ?

Can you post the output of "lspci -v", "ifconfig -a", and any messages 
in "dmesg" relating to your ethernet devices?

Thanks,

Re: Booting up the most recent 2.6.29-rc3 (pv_ops Dom0 support) under Xen Unstable on Intel SATA (AHCI) box

[Boris Derzhavets]

[-- Attachment #1.1: Type: text/plain, Size: 1233 bytes --]

  I was able to obtain access to LAN and WAN ( via ADSL) from Xen Unstable (2.6.29-rc3 kernel) Dom0 just made a switch to first integrated Ethernet Adapter - Marvell Yukon 8056 (ASUS P5K Premium/WIFI)
I believe we have a kernel driver issue with RTL 8110SC/8169 Gigabit
Ethernet. 
   Same Xen Unstable Dom0 with Novell's xen-ified kernel
2.6.27.5 works fine with Realtek Gigabit Ethernet 8110SC/8169.

Thanks.
Boris.

Can you post the output of "lspci -v", "ifconfig -a", and
any messages in "dmesg" relating to your ethernet devices?

Thanks,

[PATCH] x86: style fascism for xen assemblies

Impact: style cleanup

Make the following sytle cleanups.

* drop unnecessary //#include from xen-asm_32.S
* compulsive adding of space after comma
* reformat multiline comments

pulled, thanks Tejun. (I have amended the cleanups - there was a typo in the 
changelog and a few places were missing.)

I don't really like what you've done here.  There are two problems:

    * If you're going to convert comments of the form

      /* This is a small comment which
         happens to be longer than a line. */
          

      then you should convert it to full winged-style, rather than just
      sticking '*' on the front of the second line.
    * All the big block comments look crowded and cramped now, which
      makes them harder to read and maintain.  All those '*'s are just
      visual noise. (They make a bit more sense in C code to distinguish
      comment from code, but asm code looks so different from comment
      that they're not necessary here.)

But Ingo's already pulled it, so I guess I'm stuck with it.

i pulled it and i already fixed all the proper winged style comments as 
well. Could you double-check the end result please?

I find fully winged style a bit excessive when a comment is in the
middle of code and not very long so I kind of just chose middleground.

Yeap, I really didn't expect everyone to be happy about it.  Style
cleanups always get ugly, so the fasicm joke on the subject.  Anyways,
if you feel strong against it, please feel free to change.  I
personally don't mind one way or the other.  I just wanted to make
things more consistent while at it.

Thanks.

[PATCH 2/3] xen: make direct versions of irq_enable/disable/save/restore to common code

[Jeremy Fitzhardinge]

Now that x86-64 has directly accessible percpu variables, it can also
implement the direct versions of these operations, which operate on a
vcpu_info structure directly embedded in the percpu area.

In fact, the 64-bit versions are more or less identical, and so can be
shared.  The only two differences are:
 1. xen_restore_fl_direct takes its argument in eax on 32-bit, and rdi on 64-bit.
    Unfortunately it isn't possible to directly refer to the 2nd lsb of rdi directly
    (as you can with %ah), so the code isn't quite as dense.
 2. check_events needs to variants to save different registers.
