Driver support mmap

I am trying to make the device memory mapping work inside driver to support mmap. I implemented xxx_segmap and xxx_devmap, inside xxx_segmap I called devmap_setup() and in xxx_devmap() I called devmap_devmem_setup(). My user test program calling mmap returned successfully.
addr =(unsigned char *) mmap(....).
whenever I did addr[0] = 'm', I got the system watchdog reset.
wheneven I did printf("%x", addr[0]), I got Bus error.
What's wrong with my driver's entry point or my test program.
I do have any problem with kernel memory mapping with devmap_umem_setup.
Thanks driver gurus!

I saw from another thread that you solved your problem.
I have the same problem, and I hope you're around to
tell me how you solved it.

Printer Driver Support for Computers Running Windows 8 Release Preview

Printer driver support for computers running Windows 8 Release Preview
HP is working to help customers have the best experience with HP printers connected to PCs running the final release of Windows 8. The pre-release time is a development period when HP develops and tests printer driver solutions. HP’s current plan is for Windows 8 compatible printers to be available when the new operating system is released to the public. HP is working with Microsoft to include drivers in the Windows 8 operating system for HP printers introduced in recent years.
There may be a variety of sources for a printer driver/solution for your HP printer on a computer running Windows 8 Release Preview.
inOS:
An in-Operating System (inOS) driver is a basic driver that is included within the operating system. You do not need to download or install any software from HP. Windows 8 Relase Preview contains several inOS drivers. If an inOS driver is available for your printer, you will have at least basic print capability with USB and Network and basic scan capability with USB only (if your printer supports scanning).
Windows Update:
There might be a more functional or more up-to-date driver available for your printer through Microsoft Windows Update. If Windows Update is enabled, then the Windows Update process activates automatically when you connect (USB and Network connections) the printer to the computer. It searches online for the most recent print driver on the Windows Update site. If the online driver is more functional than the currently installed driver in Windows 8, the computer downloads and installs this driver.
HP Supplied Printer Driver/Solutions:
Although HP does not formally support any pre-release versions of Windows Operating Systems, including Windows 8 Release Preview, we may supply some full functionality drivers* prior to the official release of Windows 8. These drivers may be supplied as a courtesy to our valued HP customers through this Support Forum, though no formal support will be available otherwise. We welcome feedback within these support forums. Please check back for further updates as the official release of Windows 8 approaches.
* Full feature drivers provide full product functionality, plus valuable software to help you get the most out of your printer.

How can I partition my external hard drive supporting mac OS in one partition and windows OS in another?

Hello everyone, how can I partition my external hard drive supporting mac OS in one partition and windows OS in another?

OK. Start with:
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to two (2). Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Click on the Erase tab in DU's main window. Select one of the two partitions, preferably the first one, change the Format type: to MSDOS then click on the Erase button.

Yet another MacBook Pro touchpad driver support thread (regarding KDE)

Hi
I recently bought a MBP Retina 13" Late 2013, just because this masterpiece of hardware has the best price-performance ratio in this price segment. OS X sucks, because developing on it in a scientific way is a pain. GTest with c++11 problems, curious compiler, no (gnu) g++, no sophisticated vim etc etc ... I just wanna get back to bleeding edge software and pacman. Theres just one thing: I dont want to pay 1500 € for kickass hardware, when I cant use it. So I want to ask what's the recent state of the touchpad support of linux. I wish to have those features with KDE:
- 3 finger swipe to change desktops
- normal 2 finger swipe support to scroll vertically
- eventually horizontal 2 finger swipe to move backward and forward (filebrowser/webbrowser)
- 2 finger pinch to zoom
- 3 or 4 finger pinch to make cool things like expose, which kde has
- Don't care about rotation stuff
Basically most of this would be manageable, if I could convince KWin to recognize those gesture. How far goes current driver support to realize those things genrally? Are all those things like swipe in from edges, pinch/swipe horiz./swipe vert. with 2, 3 and 4 fingers supported and further how are they handled/given to X?
Regards, Manuel

I have no solution to any of your questions, but I am also very interested in their answers. I hope someone can shed some light on this issue or _real_ multitouch on linux in general.

LabVIEW RT driver support for CEI-620?

Hi All,
I am using PXI-8106 to run heavy-duty communication and one chasis holds the CEI-620 card (third party ARINC429 card from GE, formerly Condor Engineering). Currently on the PXI controller only runs LabVIEW RT (Pharlap) since I did not want to install Windows OS to slow the performance. Now here it is the problem, GE does not provide LabVIEW RT driver support for CEI-620 (they do have LabVIEW RT support for CEI-830 though, but that card is PMC interface). Basically right now MAX can not recognize the CEI-620 card on the host side, and I can not deploy my ARINC429 application VI to the target PXI controller. I am wondering anybody here has encountered the same problem and develop the LabVIEW RT driver for CEI-620 on his own?
Thanks.

Hi,
Unfortunately I don't have much more information to offer. I would suggest checking to make sure you have all the correct device information whe you create the ini file. I think you should still be able to develop a driver for a poll based device. It should be easier to generate an ini file if you do not require interrupt information. Make sure you have the correct identification information and try using the VISA Driver Development Wizard again.

Are there any sound cards with best driver support for Arch?

I was wondering if there are any sound cards that have the best driver support for ArchLinux? I currently own a Creative Labs X-FI Platinum Edition. The main reason I like the Platinum is that has an interface you can plug MIDI and Audio ports into. It seems to me, however, that Creative is the worst company to support Linux drivers. If anyone has any opinions, please feel free to comment. According to all my research, ALSA sound drivers are the most supportive for sound. Am I also correct in this assumption?

yeah, creative sucks. go with m-audio. they support linux unlike creative.

Will iCloud Drive support Spotlight comments? If so, will they be accessible and capable of being edited on an iPhone or iPad?

I like to remind myself of next actions for my files and folders on my Mac by using the Spotlight comments in OS X. I noticed iCloud Drive is going to support "Tags" in OS X Yosemite.
Question: Will iCloud Drive support Spotlight comments (in addition to Tags)? And, if so, will I be able to access and manipulate those Spotlight comments on my iPhone or iPad?

If you really want to import as a WAV file, go to Edit > Preferences > General > Import Settings, and set "Import Using" to "WAV Encoder," as shown below. Then rip the CD.

Lenovo G500 Lack of driver support

Greetings! I would to ask more attention for Driver Support!I'm not entirely satisfied with driver support although the product is good thats why i did choose Lenovo. I know this is not the newest series by Lenovo but still you should support. (other series as well)The latest Video, audio driver is from 2013! So this is the way where Lenovo must be improve to satisfy product users! Regards,Robert

I had a really hard time when they were working on the laptop (or thinking about it). I was using as borrowed laptop, and the pictures were sent to a non-persistent laptop. Remember, they kept the laptop so long (3 weeks) that I had to buy a W510 to be able to continue working. So, to answer your question, I cannot find the pictures.
The pictures did not tell me anything, as it was hard to see the substance they were implying was there. In my research, it appears that both the W500 and the W510 have heat problems, so I think they are finding innovative ways to get out of fulfilling their obligation to service the warranty.

Which expresscard flash drives support sleep ?

What expresscard flash drives support sleep ?

Hi patrick,
I can't give you a direct answer, but have a look at http://www.xlr8yourmac.com/feedback/express34cardreports.html in which a great many cards are commented on. THose doing so were specifically asked to mention any sleep behaviour, either good or bad, and many of them have done so.
Not all the cards are "flash" drives, of course (most, in fact are for eSata interfaces) , but it provides a very valuable compendium of information about user experiences with a variety of brands and models.
Well worth a look and may give you a few other things to ponder, too.
Cheers

JDBC Thin Driver Support for Data Encryption and Integrity

Hello JDev Team,
I am trying to implement JDBC Thin Driver Support for Data Encryption and Integrity.
It works fine with java.sql.Connection and java.util.Properties like in the following code:
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Properties props = new Properties();
int level = AnoServices.REQUIRED;
props.put("oracle.net.encryption_client", Service.getLevelString(level));
props.put("oracle.net.encryption_types_client", "( RC4_40 )");
props.put("oracle.net.crypto_checksum_client",Service.getLevelString(level));
props.put("oracle.net.crypto_checksum_types_client", "( MD5 )");
Connection conn = DriverManager.getConnection ("jdbc:oracle:thin:@localhost:1521:main", props);
etc...
But I am developing an application with InfoSwing components and it has a different way to connect to Oracle database using oracle.dacf.dataset.connections.Connection, like this:
sessionInfo1.setAppModuleInfo(new ModuleInfo("bc", "BcModule"));
sessionInfo1.setConnectionInfo(new LocalConnection("JDBCThin"));
sessionInfo1.publishSession();
My question is:
Is there any way to implement DataEncryption and Integrity into this type of connection?
Thanks a lot in advance.

Victor,
No, you can't do this from DAC, but I've been discussing it with the developer, and we both think this capability would be useful to have, so I've logged it as an enhancement request.
I do have a question for you. Once you've made the JDBC connection, do you need access to the Connection object afterwards? We're thinking of how the change could be implemented, and one way would be to allow you to pass in a Properties object when creating your own NamedConnection.
Thanks
Blaise

Hello,?I just bought for a friend a X-Fi Xtreme Audio OEM?for it's new computer but now I'm trying to find a driver compatible with vista 32bit and there's no driver support.

Now is there someone who?know how to install this card to have proper sound because without the driver the sound is horrible. Thank you

Well, maybe you should search the Gateway Support site?There is a complete installation package (307MB):ftp://ftp.gateway.com/pub/hardware_support/drivers/win_vista/audio/D2022-00-00.exe?

Which flash Drives support OS X Mavericks

which flash drives support OS X Mavericks

Virtually any flash drive, thumb drive, or whatever you want to call them will work with Mavericks if they have a USB or even Firewire interface. As far as I know, all of them will come formatted FAT or ExFAT and Mavericks can read and write to FAT or ExFAT volumes. Personally unless there is a necessity for compatibility with Windows boxes I generally reformat mine to Mac OS Extended (journaled) for full feature compatibility with the Mac, but that is just me.
