[Kernel-packages] [Bug 1511855] Re: Some Sony Dualshock 4 controllers do not work in kernel 3.15+
I confirm the issue is present in Ubuntu 15.10 (kernel 4.2) and fixed by running latest 4.5 RC kernel. It is maybe worth to note the the issue regards only bluetooth connection. The controler works fine using USB cable also with previous kernel versions. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1511855 Title: Some Sony Dualshock 4 controllers do not work in kernel 3.15+ Status in linux package in Ubuntu: Incomplete Bug description: I'm testing in Ubuntu 15.10 with kernel 4.2.0-16.19 but this bug report actually applies to ALL kernels starting at 3.15 until the current 4.3rc7 and is not limited to Ubuntu. I have a brand new Sony DualShock 4 that seems to use a slightly different protocol than the hid-sony driver expects. I'm not sure why this controller is different. Maybe updated firmware from Sony or maybe because it has never been connected to a PS4. Whatever the case, the device descriptor size is different from what hid-sony expects and because of that it does not remap the descriptor table as required. This causes only the trackpad to function (the trackpad uses a different code path) and none of the other controls work. So basically the controller does not work at all. I have created a patch that fixes it. I have only tested the patch against kernel 4.2 and 4.3 but it's simple enough that it should be trivially portable to any 3.15+ kernel. The attached patch is based against the Ubuntu mainline-crack git v4.2 kernel. I posted to the LKML asking if the descriptor size check was even necessary but never got a response so I left it in.

[Kernel-packages] [Bug 1326567] Re: [Asus M4A88T-M] problem with drm:drm_mode_addfb and drm:radeon_crtc_page_flip
Looking at the description of above macros at ./include/drm/drmP.h the logging is active only when drm.debug kernel option is set. Indeed I found this option in my /etc/default/grub file: GRUB_CMDLINE_LINUX_DEFAULT=plymouth:debug splash quiet drm.debug=0xe It seems the option is not default in recent Ubuntu release (at least 14.04), becouse restoring content of the file to default makes the line look like this: GRUB_CMDLINE_LINUX_DEFAULT=quiet splash How the drm.debug option did get to the configuration file I don't know. Maybe this is remainder from prevoius Ubuntu release ant stayed after upgrade ? Thus there is no need to recompile kernel modules, just remove the drm.debug kernel option from /etc/grub/default and regenerate grub configuration with update-grub. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1326567 Title: [Asus M4A88T-M] problem with drm:drm_mode_addfb and drm:radeon_crtc_page_flip Status in “linux” package in Ubuntu: Incomplete Bug description: My kern log is full of literally millions of entries like this: Jun 1 07:51:05 atkinson-phenomIIx4 kernel: [119346.952590] [drm:drm_mode_addfb], [FB:58] Jun 1 07:51:05 atkinson-phenomIIx4 kernel: [119346.952610] [drm:radeon_crtc_page_flip], flip-ioctl() cur_fbo = 8803de155400, cur_bbo = 880407586000 Jun 1 07:51:05 atkinson-phenomIIx4 kernel: [119346.952632] [drm:radeon_crtc_page_flip], flip-ioctl() cur_fbo = 8803de155400, cur_bbo = 880407586000 I have found places where other have the problem.

Thanks Christopher but I think my problem is pretty the same as in this bug report. Looking at the source code provided with Ubuntu 14.04 distribution it seems the reason is just some debug logging switched on in the kernel file: linux-source-3.13.0/drivers/gpu/drm/radeon/radeon_display.c There is radeon_crtc_page_flip function that contains: DRM_DEBUG_DRIVER(flip-ioctl() cur_fbo = %p, cur_bbo = %p\n, work-old_rbo, rbo); The command is called unconditionally.
