Problems when try to alloc user bo using TTM
Hi all:
TTM provide "ttm_bo_type_user" which create bo from user space memory.
I try to use this functions, but find some problems:
1. Can not get "pages" when driver try to bind user pages to GPU apterure.
ttm->state set to "tt_unbound" when add ttm structs, while
ttm_tt_populate prevent driver populate function called if ttm->state
is not "tt_unpopulated"
int ttm_tt_populate(struct ttm_tt *ttm)
{
struct page *page;
unsigned long i;
struct ttm_backend *be;
int ret;
if (ttm->state != tt_unpopulated)
return 0;
2. Page number may not be the size it rounded up.
eg.
supports allocate a user space BO size=5K, which round up to 2
pages,but it should be 3, if the user space memory like this
page1 page2 page3

[Bug 25052] kernel modesetting still does not work
https://bugzilla.kernel.org/show_bug.cgi?id=25052 --- Comment #17 from Elmar Stellnberger 2011-02-23 21:29:44 --- Concerning your patches I believe that they will be valuable for many users (although I could not verify them for me yet.). As I have found out flawed EDIDs are a known problem and thatways f.i. already addressed by the proprietary fglrx driver through letting the user select out of a prewritten list of artificial EDIDs for known monitor types. Nonetheless just using the EDID of another port of the same monitor or just suppressing the checksum test promises to be a more gracile way of resolving such an issue. That is basically why I want to make a commit request for these patches to be acquired in the final openSuSE 11.4 release within 15 days so that more people can test these options (mentioning them in the release notes with a demand to report the results for finally acquiring the patches into the mainline kernel.). As far as now I would also issue the following additional feature requests for an in future comprehensively EDID relied graphics system: (1) kernel option for using a user supplied EDID (instead of the hw. supplied ED.) (2) option(s) for Xorg or the radeon kernel module to achieve the same: rebooting is painful and the typical user will have to test different things. If Xorg quits without success in modesetting (as so often by 2.6.36.1-1) or detects a wrong EDID checksum then it should point the user on the fgconsole to try them. by the way: Do you know whether the nouveau driver does already fully rely on KMS? -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are watching the assignee of the bug. -- Free Software Download: Index, Search & Analyze Logs and other IT data in Real-Time with Splunk.

https://bugzilla.kernel.org/show_bug.cgi?id=25052 --- Comment #16 from Elmar Stellnberger 2011-02-23 20:45:45 --- As Comment #15 shows there is currently something more fundamentally messed up with KMS (which is apparently not EDID-related). Actually the situation has rather deteriorated instead of improving: 2.6.34-12.1 & -9.3: itg: works, ext: dark 2.6.36.1-1, Comment #1: non-deterministic, once it worked for both monitors 2.6.38-0.0.12: both monitors: vertical pixelry, nothing works (results completed by downstream report from openSuSE as linked by Comment #1.) If it works for other cards KMS does probably have a problem with ATI or just ATI Mobility 2xxx cards (I am planning to make a request to the oS core test team in this regard and will tell you as soon as results should become available.). -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are watching the assignee of the bug. -- Free Software Download: Index, Search & Analyze Logs and other IT data in Real-Time with Splunk.

[Bug 25052] kernel modesetting still does not work
https://bugzilla.kernel.org/show_bug.cgi?id=25052 --- Comment #15 from Elmar Stellnberger 2011-02-23 20:27:24 --- Unfortunately the tests of Comment #14 were not significant. I have tested the patches with the same kernel but a different Xorg namely xorg-x11-server-7.6_1.9.3-122.1 and xorg-x11-driver-video-7.6-180.1 which however now does resolve UMS for radeon so that everything does again work without any patch and kernel option. With a full KMS kernel like 2.6.38-0.0.12 on the other hand unfortunately video mode initializtion does at me currently not work at all under any configuration: neither with the integrated monitor nor with my external one over any of the ports DVI, HDMI or VGA. Here are the exact results: VGA: itg: colored vertical lines; ext: c.v.l.(the same), mouse: pixelry HDMI: itg & ext: colored lines; this time brighter with more white, mouse: same DVI: itg: 1st: colored lines; 2nd: sparse colored lines ahead of white bg, ext 1&2: at first 'no signal'-dark then the same as for itg, mouse: same As the screen output for DVI has differed between two consecutive test runs I presume that there is no substantial difference in the result between different monitors and ports (always vertical colorful lines). The mouse did at first never appear until you moved it into the upper left screen area where there would normally appear an xterm by xinit. From then on the mouse pointer was represented by a rectangular pixel surrogate. Rebooting was the only escape though the system was still reactive (no crash or hang): changing the virtual terminal (chvt) or exiting X from an exit typed into xterm both resulted in a fully blackened screen with no more output. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are watching the assignee of the bug. -- Free Software Download: Index, Search & Analyze Logs and other IT data in Real-Time with Splunk.

I finally got some time to test with a stable kernel, and as of 2.6.37, as best I can tell (this one bedeviled me to the point I'm reluctant to say it's for sure fixed now, without a YEAR of it not coming back!), it's fixed. The kernel comes back up and from CLI (there's major X corruption preventing use of it after restore, but that'd be a different bug), I can dmesg, which clearly shows (1) an initial failure to read the drive's ID info properly, as before, but now, (2) instead of kicking it out to sde (with sd[a-d] normal) or whatever as it did before, it apparently retries and comes up with the proper ID, thus returning the drive to the proper sd[a-d] letter and its partitions to the proper place in their assigned md/RAIDs. On a slightly different note, a big THANKS! to whoever introduced and continues maintaining magic-sysreq. I had a hardware issue for awhile and at first thought it was yet another pre-release kernel bug. A bit of circuit-trace paint later (expensive keyboard) and it's working fine again, but as often the case, I didn't realize how much I took that feature for granted until it failed. And of course, thanks for getting the device-id detect and if necessary retry working, too. =:^) Now to see how 2.6.38 is coming along. Maybe the radeon graphics restore-state-on-resume works better now.
