Re: about NKPT on amd64
Hi, Alan Cox
Thanks for your reply. I want to know why the NKPT set to 32 in
revision187465,
is it possible that set NKPT less or lager than 32? What's the limitation if
set NKPT to 32?
I also guess the KPTphys[] not used in kernel initialization on amd64 in
revision187465. And
I notice that in revision189075, in function pmap_init() the vm page array
entries for the kernel
pmap's page table pages is initialized; but in revision187458, the
initialization is not performed.
I guess the earlist part of the kernel's initialization is the
pmap_bootstrap(firstaddr),
this will call function create_pagetables().
In function create_pagetables(), we first use allocpages(firstaddr,
NKPT) to
allocate NKPT pages, then initialize the KPTphys[] and KPDphys[]. But then
the KPDphys[] re-initialize the range (0, *firstaddr) in 2MB page:
/* Map from zero to end of allocations under 2M pages */
/* This replaces some of the KPTphys entries above */
for (i = 0; (i PDRSHIFT) *firstaddr; i++) {
((pd_entry_t *)KPDphys)[i] = i PDRSHIFT;
((pd_entry_t *)KPDphys)[i] |= PG_RW | PG_V | PG_PS | PG_G;
}
This means that the KPDphys[] will be override completely if the range
(KERNBASE, virtual_avail)'s size larger than 64MB, so I guess that the
KPTphys[]
not used anymore if the range (KERNBASE, virtual_avail)'s size larger than
64MB.

Hi, Alan
I'm study the Revision 187465 : Prepare for a larger kernel virtual
address space. After read some relative source code, I have an
question about the macro NKPT on amd64: why 32 is enough for the
kernel page table pages? Do it means that the range (KERNBASE,
virtual_avail) should always less than 64MB( 32 * 2MB)?
NKPT sets the size of the kernel page table during the earliest part of
the kernel's initialization. After that, the size of the page table
grows dynamically according to usage.

(Forget about sudo, I am administering these boxes and don't want to type sudo for every single command, it's not a user machine).

Oh the joy of cloud computing, erm... discussion. :-) One of my biggest gripes with the ports system is dependency hell. Ports link against so my optional components and pull them into the install. Libraries and components are built based on make file defines. If you do install a program via pkg_add (it's about precompiled binaries, so no Makefile involved, not even a ports tree), there are also means to determine if something ELSE is needed - as a dependency. Hard disk space is cheap today, so 99% of users don't even bother installing all the stuff they primarily won't need, but the program THAT they need insists on it. But this doesn't have to be so. It's possible and easy enough to check a running system for which libraries are installed and only if a feature is enabled to load the library. It already works that way. Say program A needs B of version n as dependency, then B(n) has to be installed even if B(n-1) is already present on the system. This is no big deal if B isn't installed at all, but requires caution when it is (at version n-1). Of course, B may have other dependencies that do not matter to A, but to B, so even C(m) gets installed. The number of console programs that want to pull in X window or kde is my boggling. Hmmm... The only one I remember being that way is the old cvsup, but there was nocvsup-nogui (or -nox11?). Knowing how to program myself when I see a make config menu on every single port it makes me want to cry. You can script those mechanism, so you get rid of that interaction and can use file-defined settings. I think the make config menus should have everything checked by default and only be provided to prevent things from being compiled such as for embedded devices. Oh no, please - NO! Everything checked by default? That would be problematic for those who, for example, don't WANT to use HAL+DBUS because it just doesn't work for them. Or people who have security concerns (or maybe even external regulations) so they do not want to install something. And remember: Regarding codecs for mplayer and mencoder, it's illegal to listen to MP3 in the US! :-) My question is why is this so? Why can't programs do more run time configuration? Is a configuration run time system library needed to make it easier? You're bringing up an interesting idea, but runtime detection of library (or feature) availability seems to be very time consuming to me. An example is mplayer. On older system, I did always compile it to match the CPU that is present, means NO runtime CPU detection. Why? Because it often runs too slow on older system if enabled. And let's assume another typical example from the multimedia sector. You have installed mplayer and want to play MP3 audio or an MPEG video file, or even a DVD - which is completely illegal in the US. :-) But there is no libdvd installed, and no MP3 codecs for playing or encoding. What should happen? Upon first start, should the program request you to download and install them? But what if the system is offline? I would assume it's better to install all the stuff needed at install time, no matter if being from ports or as a package. The problem with packages is that most ports have so many options that it would result in 2^x packages if the port has x options. And how should the ports then be named? Should the selected options be abbreviated and in alphabetical order? Well, I would REALLY like to have a USABLE set of options predefined and compiled into the packages. I know that this may very problematic (see codecs), and the packages usually are made using the DEFAULT options which may not be the OPTIMAL options for everyone. And sometimes, there even isn't a package (e. g. OpenOffice) with the required set of options, and even if it is, half of the stuff one assumes is missing (also see OpenOffice). So there is still stuff one needs to compile, and YOU are in charge to define the options you need.

I found the sysctl kern.maxusers but I'm unsure how things affects things. Can I reduce the amount of time, memory, etc the kernel spends enforcing quota, scheduling, etc? I don't have anything particular in mind - just want to get a general set of tunables I might be interested in. -- Eitan Adler ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Oh the joy of cloud computing, erm... discussion. :-) Wasn't that the a subplot of the hitch hikers guide? That the sum of human consciousness is just a cloud computer? New term, old idea. One of my biggest gripes with the ports system is dependency hell. Ports link against so my optional components and pull them into the install. Libraries and components are built based on make file defines. If you do install a program via pkg_add (it's about precompiled binaries, so no Makefile involved, not even a ports tree), there are also means to determine if something ELSE is needed - as a dependency. Hard disk space is cheap today, so 99% of users don't even bother installing all the stuff they primarily won't need, but the program THAT they need insists on it. Ports or packages, what I'm discussing is minimizing dependencies. I compile my own packages and use them across all my computers. What I'm saying I'd like to see is minimal installs. If you need a feature like for instance LDAP or SQL then you need to install that port. Need another feature? Install yet another port. The program should detect that new programs/libraries are available or at a minimum enable them though uncommenting a line in a conf file. But this doesn't have to be so. It's possible and easy enough to check a running system for which libraries are installed and only if a feature is enabled to load the library. It already works that way. Say program A needs B of version n as dependency, then B(n) has to be installed even if B(n-1) is already present on the system. This is no big deal if B isn't installed at all, but requires caution when it is (at version n-1). Of course, B may have other dependencies that do not matter to A, but to B, so even C(m) gets installed. And that's the mess I don't like. It's like the six degrees of separation rule. Installing one application sometimes means installing 100 other ports/packages with features the average user has no need or interest in yet. I'm just saying we should have to need to install/compile all those packages when we don't need them and we should have to need to recompile ports just to add a new capability. The number of console programs that want to pull in X window or kde is my boggling. Hmmm... The only one I remember being that way is the old cvsup, but there was nocvsup-nogui (or -nox11?). Well I decided I wanted to try to setup pulseaudio as a network sound server on a headless computer and it pulled in X. Sure I could recompile just for that one computer. But that isn't elegant. The storage space doesn't matter. What annoys me is the installation time and the longer compile time as well as to some extent downing time. I think the make config menus should have everything checked by default and only be provided to prevent things from being compiled such as for embedded devices. Oh no, please - NO! Everything checked by default? That would be problematic for those who, for example, don't WANT to use HAL+DBUS because it just doesn't work for them. Or people who have security concerns (or maybe even external regulations) so they do not want to install something. And remember: Regarding codecs for mplayer and mencoder, it's illegal to listen to MP3 in the US! :-) The point would be that the programs wouldn't have those features enabled by default, you have to configure them or the program can auto-detect. My question is why is this so? Why can't programs do more run time configuration? Is a configuration run time system library needed to make it easier? You're bringing up an interesting idea, but runtime detection of library (or feature) availability seems to be very time consuming to me. An example is mplayer. On older system, I did always compile it to match the CPU that is present, means NO runtime CPU detection. Why? Because it often runs too slow on older system if enabled. Well obviously that one actual good reason for people to compile their own ports. Nothing can change that. What I'm saying is that libraries and features shouldn't be in the config menu. And let's assume another typical example from the multimedia sector. You have installed mplayer and want to play MP3 audio or an MPEG video file, or even a DVD - which is completely illegal in the US. :-) But there is no libdvd installed, and no MP3 codecs for playing or encoding. What should happen? Upon first start, should the program request you to download and install them? But what if the system is offline? I would assume it's better to install all the stuff needed at install time, no matter if being from ports or as a package. If it worked like like would like then you wouldn't be able to play those files unless you downloaded another package or compiled the ports
