| valkyr | hi | 12:53 |
|---|---|---|
| valkyr | Correct me if Im wrong .. but 32bit Linux systems are also limited to under 4gb of ram right? To increase limit one has to either upgrade to a 64bit version or update the kernel with a PAE aware kernel. Would you all agree? | 12:53 |
| domas | right | 12:54 |
| valkyr | thanks | 12:54 |
| domas | (PAE kernel doesn't allow you to address all memory in application though ) | 12:54 |
| valkyr | in which case what do i do? | 12:56 |
| valkyr | there's no other choice here but to use PAE or just upgrade right | 12:56 |
| domas | you use 64 bits | 12:57 |
| domas | ;-) | 12:57 |
| valkyr | heh alright | 12:58 |
| domas | windows have AWE, which allows applications to address larger areas, but I have no idea how it works ;-) | 12:58 |
| valkyr | thanks :)) | 12:58 |
| valkyr | well we won't have no use for windows here | 12:58 |
| domas | there's specific API | 12:58 |
| valkyr | domas: going back to what you said | 12:58 |
| valkyr | in a single process is what oyu mean right? | 12:58 |
| domas | yes | 12:58 |
| valkyr | ok | 12:59 |
| domas | (I'm working with multiple software pieces that loves memory ;-) | 12:59 |
| valkyr | s0 same limitation per process as you have system-wide with a non-PAE kernel? | 12:59 |
| domas | actually, with non-PAE kernel you can allocate ~100MB more of memory ;-) | 13:00 |
| domas | or maybe not | 13:00 |
| domas | 32-bit linux gives you about 2.7G per app | 13:00 |
| domas | and maximum contiguous allocation can be less (close to 2G) | 13:00 |
| valkyr | they say that PAE slows the system down somewhat, but I've never heard any XP user complain about it. | 13:00 |
| domas | if PAE would slow the system down, ubuntu-server kernels (all with PAE) would not be that usable, right? | 13:00 |
| domas | maybe using memory via AWE is slower than directly, I don't know ;-) | 13:01 |
| valkyr | ok you're not a kernel dev? | 13:01 |
| valkyr | :P | 13:01 |
| domas | I do some development for myself sometimes ;-) | 13:01 |
| valkyr | XP switched to a PAE kernel with SP2. They still limit the memory in order to not confuse drivers. | 13:01 |
| valkyr | so I don't know how big the difference in performance can be in practice. | 13:01 |
| domas | I doubt there is any | 13:02 |
| valkyr | ok | 13:03 |
| domas | 1% | 13:04 |
| domas | ;-) | 13:04 |
| valkyr | 1%? | 13:04 |
| valkyr | yu checked? | 13:04 |
| * domas points at http://people.redhat.com/nmurray/RHEL-2.1-VM-whitepaper.pdf | 13:05 | |
| domas | "The performance impact is highly workload dependent, but on a fairly typical ker- | 13:05 |
| domas | nel compile, the PAE penalty works out to be around a 1% performance hit on Red | 13:05 |
| domas | Hat?s test boxes. Testing withhits ranging from 0% to 10%" | 13:05 |
| domas | damn pdf copypaste | 13:05 |
| domas | mangled the text ;-) | 13:05 |
| valkyr | ah | 13:05 |
| valkyr | could get a second opinion on this from one of the devs too | 13:05 |
| valkyr | thanks for the link | 13:05 |
| domas | I prefer x86_64 ;-) | 13:07 |
| valkyr | so using memory via AWE is slower? | 13:09 |
| valkyr | domas so with non-PAE you can allocate more than 1--mb | 13:18 |
| valkyr | 100mb | 13:18 |
| valkyr | cant see it in the link though | 13:18 |
| domas | noooo | 13:19 |
| domas | with PAE kernel you can allocate ~2.7G | 13:19 |
| domas | with non-PAE it is closer to 2.8G | 13:19 |
| domas | ;-) | 13:19 |
| valkyr | /<domas> actually, with non-PAE kernel you can allocate ~100MB more of memory ;-) | 13:19 |
| domas | 'more' | 13:19 |
| valkyr | ohh | 13:19 |
| valkyr | so with a non-PAE kernel you dont have that many limitations to a PAE kernel? | 13:20 |
| domas | well, it is just small difference | 13:20 |
| valkyr | but per process, they're both limited equally | 13:21 |
| valkyr | non-pae and PAE right? | 13:21 |
| domas | nono, I'm talking exactly about per-process | 13:21 |
| domas | PAE kernel can allocate much more overall | 13:21 |
| valkyr | i dont gain anything more from using a non-PAE here do i | 13:21 |
| domas | nope | 13:21 |
| valkyr | ok | 13:22 |
| valkyr | thx domas | 14:15 |
| Kano | hi, i just looked at your linux-firmware package, a few files could be added | 15:31 |
| Kano | you have got only 2 of 3 possible firmware files for ar9170, the correct one for AVM Wlan N sticks is missing | 15:32 |

| Kano | also for your other non-free package | 15:33 |
| Kano | there you could add xc3028-v27.fw as dvb firmware | 15:34 |
| Kano | and dont say there is no bug... | 15:36 |

| setuid | How do I ensure that the same initramfs/initrd that is used to successfully boot a 2.6.28-5 kernel on Jaunty, is used to generate a working 2.6.28-15 version? | 18:47 |
| setuid | because 2.6.28-15 is unbootable | 18:48 |
| setuid | What is it that governs what modules/etc. are included in an initramfs? | 19:32 |
| setuid | Because I can't seem to generate one for 2.6.28-15-generic that models the same modules/support that is included in the default 2.6.28-5 that I'm using right now. | 19:32 |
| jk- | hey setuid | 19:32 |
| setuid | hola | 19:32 |
| jk- | setuid: /etc/initramfs-tools/modules ? | 19:33 |
| setuid | Ok, so when I run: update-initramfs.distrib -c -k 2.6.28-15-generic | 19:34 |
| setuid | It should generate a working one... but doesn't | 19:35 |
| setuid | I get a hard-lock, when it tries to mount the root volume, using a UUID (the same construct that works with 2.6.28-5) | 19:35 |
| setuid | So any ideas? | 19:46 |
