Allocating contiguous memory (shared dma) under x86 solaris 8
How can I allocate a contiguous dma buffer? I've been able to do this on a sparc-based system. I'm interested on how it can be done on an x86-based system. I'm using ddi_umem_alloc to allocate the buffer because I need to export it to user space. I get more than one cookie back from the ddi_dma_addr_bind_handle call. My device does not support scatter-gather, which means I must have one cookie. Any help is greatly appreciated!
Thanks in advance!
Perhaps this is a simpler question to ask: can anyone tell me which functions, if any, are guaranteed to return memory which is contained in physically contiguous pages, (useful for dma)? And what parameters do I have to set to make this happen?
e.g. ddi_mem_alloc? ddi_umem_alloc? ddi_dma_mem_alloc?
Again, thanks.

64-Bit PHP on x86-Solaris 11.1
Hi all,
we have just set-up a x86-Solaris 11.1 based workgroup server which will be mainly used for web-based applications (like ownCloud, Moodle or openAtrium) at our university institute. As some of the members of our workgroup produce media (i.e. full HD videos), we have to deal with files larger than 2 GB. While it isn't any problem for Solaris' Apache to handle these file sizes, some PHP applications have quite big problems to work with files >2 GB correctly as long as the underlying PHP is a 32 bit binary.
I wouldn't have expected that an Enterprise system like Solaris 11.1 still comes with 32 bit applications as the Solaris kernel itself is using the 64 bit mode on x86_64 for quite some time now. Nevertheless, as I really like Solaris' features especially for stable and large storage solutions, I want to stick with Solaris and will have to find a solution for the mentioned problem...
Recompiling PHP from the sources as a 64 bit application is not a problem. I also assume that I would also have to recompile Apache2 as a 64 bit application to get compatibility to the apache module of 64 bit PHP.
My question is: Is there any "gold standard" to accomplish this? Of course, I can recompile all parts that I need by myself, completely independently from the packaging system, and put them to "/usr/local/..." or to "/opt/local/...". I am, however, not sure if this is the best way. Perhaps there are already packages I could install and I don't know about. I can't imagine that I am the first user who experiences that problem. Would it make sense to switch to an alternative package repository like OpenCSW? What I also thought about, was the following way to proceed: I'm going to take the source packages from Oracle and then compile Apache and PHP (and most probably also MySQL) with the option for 64 bit according to the instructions in the sources. So I can also build new packages which I can deploy into the zones where I need them in.
Is there any better way which I might have overlooked, yet?
Thank you in advance for any help!
Kind regards,
SteffenI also assume that I would also have to recompile Apache2 as a 64 bit application to get compatibility to the apache module of 64 bit PHP. In S11.1 Apache is already 64-bit aware:

The problem is that 64-bit PHP isn't bundled.
You can try to rise an SR on that topic.
It seems that it would be easier to integrate large file support only in 32-bit PHP instead.
Any 32-bit application that is compiled with large file support (-D_LARGEFILE_SOURCE and
-D_FILE_OFFSET_BITS=64) will work with > 2GB files.
I think that SR could be realized relatively faster than integrating stable 64-bit PHP.

Oracle 9i and IDS under sun solaris 8
Need some help on oracle 9i and IDS under sun OS
i want some clariffication in my project.
If i develop my application under "sun solaris 8" OS for x86 with "oracle 9i"
as the backend and "IDS" (internet developer suite) as the front end, Can my
application be ported to the other environment i.e "SUNFIRE 280R" as the
server with sun solaris 8 as the OS and the same DB and front-end ?.
will there be any porting problems ?.
i am new to this environment.And i don't have SUNFIRE 280R server with me and
the customer won't supply it.
can anybody guide me please ?.(i am looking for the suggestions form those who
really worked on this environment.)

Solaris v10 sparc jumpstart server on x86 solaris - can't find miniroot.
I am trying to setup a jumpstart install server on an x86 solaris v10 machine to do a sparc network install. I downloaded both the CD and DVD sparc v10 ISO's. When I mount the CD, the Solaris_10/Tools/Boot directory (miniroot system) is symlinked back to ../../../s1 which does exist. I can't find it on the CD, I've used prtvtoc and this slice does not seem to exist.
On the DVD iso, the directoy exists, but many files cannot be read, almost like the filesystem is corrupt.
I've download these ISO and burned them many times, so I know it's not an issue with hardware or the CD/DVD media.
Where can I download a working sparc solaris v10 miniroot system?There is no such entry under solaris. This entry only exist on windows.
On solaris you need to change entries in the kjs script (prior to SP3)
or iasenv.ksh (after SP3)

Ld error under x86 when linking boost serialization
Hi all,
I am trying to compile and link boost serialization project. I am doing this work under two architectures:
- sparc using sunstudio12 libraries and CC version 5.8
- x86 using sunstudio12 libraries and CC version 5.10
Under sparc I can compile the code and generate libserialization.so, release and debug.
However, I can't generate libserialization.so under x86 environment in debug mode (release mode works)
Here are my variables:
CPPFLAGS := -w -g -DDEBUG -KPIC -features=extensions -I.
LDFLAGS := -G -Bsymbolic -Llib/x86/DEBUG -ldl -lm -lrt -lnsl -lsocket -lCstd -lCrun -I.
The link takes about 2 minutes (few sconds under sparc) and ld crash displaying this message and generating a core:
CC: Fatal error in ld: Segmentation Fault (core dumped)
make: *** [home/.../boost/lib/x86/DEBUG/libserialization.so] Error 1
I think ld crashes because I don't have enough space under the swap partition, but why is it works under sparc? and faster?
Thanks for your help,One difference is debug data is due to the compiler version, not differences between sparc and x86.
C++ 5.8 (in Sun Studio 11) generates debug data in stabs format. C++ 5.10 (in Sun Studio 12u1) generates debug data in dwarf format.
By default, stabs data remains in the .o files and is not copied into the executable program.
But dwarf data is copied into the executable. The program will need more memory when it is being linked, and take up more space on disk. (You can get the same effect with stabs if you link using the -xs option.) The dwarf data in the executable does not affect the amount of memory the running program needs, since it is not loaded into the program address space.
The advantage of putting the debug data in the executable is that you do not need access to the original .o files when debugging the program. With stabs, if you delete or move the .o files, or run the program from a location where the .o files are not visible via the original path, the debugger can't find any debug data.
Dwarf format does not allow omitting the debug data from the program; debugging via debug data in .o files is not an option. -

At some stage there are problems with creation of a new state...
I remember some time ago (Solaris 2.8) there where problems like that with ipfilter, but now ipfilter included in Solaris distribution, hardware tested and so on...
New reincarnation of a problem?
Somebody has similar problems with the software x86 Solaris 10?
Thanks, Roman Gnatenko (rvg at co.ru)Hi. I've never seen anything like this, and it seems to be something which
the JDBC module is going to be an innocent victim of, rather than a
contributor to... Your best course is to open an official support case.

Allocated heap memory goes up even when there is enough free memory
Hi,
Our Java application's memory usage keep growing. Further analysis of the heap memory using JProbe shows that the allocated heap memory goes up even when there is enough free memory available in the heap.
When the process started, allocated heap memory was around 50MB and the memory used was around 8MB. After few hours, the inuse memory remains at 8MB (slight increase in KBs), but the allocated memory went upto 70MB.
We are using JVM 1.5_10. What could be the reason for heap allocation going up even when there is enough free memory available in heap?

ATV2 - Clicking Shared Library Under Computers Loops Back To Main Screen
I see this issue following the upgrade to 4.2 on my ATV2. As the title says, when I click on my shared library under "Computers" from the main screen, it briefly shows the next screen and immediately loops back to the main screen. This is true regardless of the remote I'm using - Logitech Harmony One or the Remote app from iPad or iPod Touch. Navigating all other screens works fine from all 3 remotes. I've tried turning off/on Home Sharing - no joy.
Essentially, I'm locked out of any content from my iTunes library. Please help.Welcome to the Apple Community.
I don't believe it's anything to do with the remote. My first inclination is that something about your network or library is causing issues with the new software. Have you tried any basic troubleshooting like restarting all the devices (Inc. The router) or anything else.
