[git pull] drm radeon fixes
by Dave Airlie 15 Aug '11

15 Aug '11

Hi Linus, nothing too serious here, one regression fix across a couple of card families, and some workaround to make things work better on some Apple hardware. Dave. The following changes since commit 72fa59970f8698023045ab0713d66f3f4f96945c: move RLIMIT_NPROC check from set_user() to do_execve_common() (2011-08-11 11:24:42 -0700) are available in the git repository at: ssh://master.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6.git drm-fixes Alex Deucher (4): drm/radeon/kms: don't enable connectors that are off in the hotplug handler drm/radeon/kms: fix regression is handling >2 heads on cedar/caicos drm/radeon/kms: make some watermark messages debug only drm/radeon/kms: don't try to be smart in the hpd handler Matthew Garrett (2): drm/radeon: Allow panel preferred EDID to override BIOS native mode drm/radeon: re-POST the asic on Apple hardware when booted via EFI drivers/gpu/drm/radeon/atombios_dp.c | 12 +++++++++++ drivers/gpu/drm/radeon/evergreen.c | 2 +- drivers/gpu/drm/radeon/radeon_connectors.c | 29 +++++++++++++++++++-------- drivers/gpu/drm/radeon/radeon_device.c | 4 +++ drivers/gpu/drm/radeon/radeon_encoders.c | 3 ++ drivers/gpu/drm/radeon/radeon_mode.h | 1 + 6 files changed, 41 insertions(+), 10 deletions(-)

[Bug 38478] New: r600g fails to identify the screen refresh rate
by bugzilla-daemon＠freedesktop.org 13 Aug '11

13 Aug '11

https://bugs.freedesktop.org/show_bug.cgi?id=38478 Summary: r600g fails to identify the screen refresh rate Product: Mesa Version: git Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel(a)lists.freedesktop.org ReportedBy: steve(a)sk2.org Created an attachment (id=48172) --> (https://bugs.freedesktop.org/attachment.cgi?id=48172) Xorg log file Hi, With the current git tree (up to 2fe39b46e73aea37152777fe11d489e0b1bc3f92) I'm only getting 10fps running glxgears on my HD4650; other 3D programs exhibit the same problem. This is an improvement over previous versions of r600g on my system: before 7.10.3 the driver causes constant freezes, and 7.10.3 works but only at 0.8fps (constantly). I'm attaching the Xorg log and [drm] info from my kernel log. Let me know what other information you need and I'll happily provide it!

[PATCH] drm/radeon/kms: don't try to be smart in the hpd handler
by alexdeucher＠gmail.com 13 Aug '11

13 Aug '11

From: Alex Deucher <alexander.deucher(a)amd.com> Attempting to try and turn off disconnected display hw in the hotput handler lead to more problems than it helped. For now just register an event and only attempt the do something interesting with DP. Other connectors are just too problematic: - Some systems have an HPD pin assigned to LVDS, but it's rarely if ever connected properly and we don't really care about hpd events on LVDS anyway since it's always connected. - The HPD pin is wired up correctly for eDP, but we don't really have to do anything since the events since it's always connected. - Some HPD pins fire more than once when you connect/disconnect - etc. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=39882 Signed-off-by: Alex Deucher <alexander.deucher(a)amd.com> Cc: stable(a)kernel.org --- drivers/gpu/drm/radeon/atombios_dp.c | 12 ++++++++++++ drivers/gpu/drm/radeon/radeon_connectors.c | 14 ++++++-------- drivers/gpu/drm/radeon/radeon_mode.h | 1 + 3 files changed, 19 insertions(+), 8 deletions(-) diff --git a/drivers/gpu/drm/radeon/atombios_dp.c b/drivers/gpu/drm/radeon/atombios_dp.c index 645b84b..7ad43c6 100644 --- a/drivers/gpu/drm/radeon/atombios_dp.c +++ b/drivers/gpu/drm/radeon/atombios_dp.c @@ -613,6 +613,18 @@ static bool radeon_dp_get_link_status(struct radeon_connector *radeon_connector, return true; } +bool radeon_dp_needs_link_train(struct radeon_connector *radeon_connector) +{ + u8 link_status[DP_LINK_STATUS_SIZE]; + struct radeon_connector_atom_dig *dig = radeon_connector->con_priv; + + if (!radeon_dp_get_link_status(radeon_connector, link_status)) + return false; + if (dp_channel_eq_ok(link_status, dig->dp_lane_count)) + return false; + return true; +} + struct radeon_dp_link_train_info { struct radeon_device *rdev; struct drm_encoder *encoder; diff --git a/drivers/gpu/drm/radeon/radeon_connectors.c b/drivers/gpu/drm/radeon/radeon_connectors.c index b8ccdd7..df7ed82 100644 --- a/drivers/gpu/drm/radeon/radeon_connectors.c +++ b/drivers/gpu/drm/radeon/radeon_connectors.c @@ -64,18 +64,16 @@ void radeon_connector_hotplug(struct drm_connector *connector) if (connector->dpms != DRM_MODE_DPMS_ON) return; - /* powering up/down the eDP panel generates hpd events which - * can interfere with modesetting. - */ - if (connector->connector_type == DRM_MODE_CONNECTOR_eDP) - return; + /* just deal with DP (not eDP) here. */ + if (connector->connector_type == DRM_MODE_CONNECTOR_DisplayPort) { + int saved_dpms = connector->dpms; - /* pre-r600 did not always have the hpd pins mapped accurately to connectors */ - if (rdev->family >= CHIP_R600) { - if (radeon_hpd_sense(rdev, radeon_connector->hpd.hpd)) + if (radeon_hpd_sense(rdev, radeon_connector->hpd.hpd) && + radeon_dp_needs_link_train(radeon_connector)) drm_helper_connector_dpms(connector, DRM_MODE_DPMS_ON); else drm_helper_connector_dpms(connector, DRM_MODE_DPMS_OFF); + connector->dpms = saved_dpms; } } diff --git a/drivers/gpu/drm/radeon/radeon_mode.h b/drivers/gpu/drm/radeon/radeon_mode.h index 6df4e3c..f2e8267 100644 --- a/drivers/gpu/drm/radeon/radeon_mode.h +++ b/drivers/gpu/drm/radeon/radeon_mode.h @@ -476,6 +476,7 @@ extern void radeon_dp_set_link_config(struct drm_connector *connector, struct drm_display_mode *mode); extern void radeon_dp_link_train(struct drm_encoder *encoder, struct drm_connector *connector); +extern bool radeon_dp_needs_link_train(struct radeon_connector *radeon_connector); extern u8 radeon_dp_getsinktype(struct radeon_connector *radeon_connector); extern bool radeon_dp_getdpcd(struct radeon_connector *radeon_connector); extern void atombios_dig_encoder_setup(struct drm_encoder *encoder, int action, int panel_mode); -- 1.7.1.1

Empty /proc/dri/0/bufs queues -
by Vipin 13 Aug '11

13 Aug '11

Hello all, *I think the first message got discarded, posting a second one* I have been trying to study the radeon open source driver and have some questions after turning the debug flag on. System Information --------------- uname -a Linux gilubuntu1 3.0.1vipindebug #1 SMP Thu Aug 11 11:17:24 EDT 2011 i686 GNU/Linux kernel option - drm.debug=1 glxinfo | grep rendering direct rendering: Yes lspci -vvv | grep ATI 01:00.0 VGA compatible controller: ATI Technologies Inc RV710 [Radeon HD 4550] (prog-if 00 [VGA controller]) Subsystem: ATI Technologies Inc Device 0104 lsmod - relevant entries ttm 110688 1 radeon drm_kms_helper 49424 1 radeon drm 317625 5 radeon,ttm,drm_kms_helper agpgart 56250 2 ttm,drm i2c_algo_bit 10782 1 radeon --------------------------------------------------------------------- Question 1. Empty /proc/dri/0 bufs, queues files Is this an expected behavior ? I have tried generating extensive 3D workloads, but the file remains empty. Question 2. /sys/kernel/debug/dri/ There are two directories 0 & 64, what does the 64 entry signify ? Question 3. The contents of /sys/kernel/debug/dri/0 contains 15 radeon_ib_00xx Does this mean, the card has 15 indirect buffers ? Also, does this interface shows me the ringbuffer data like i915. Question 4. The kernel log shows entries like these (massive amounts) Aug 11 13:19:01 gilubuntu1 kernel: [ 4251.705377] [drm:drm_ioctl], pid=1544, cmd=0xc0086464, nr=0x64, dev 0xe200, auth=1 Aug 11 13:19:01 gilubuntu1 kernel: [ 4251.705394] [drm:r600_irq_set], r600_irq_set: sw int Shouldn't it have other debug entries other than these two ? Thank You Vipin Jain

Reverting rc6 by default
by Francesco Allertsen 13 Aug '11

13 Aug '11

Hi, I wanted to try the new 3.0 Linux Kernel, and I got stucked for a freeze at the start of X. I have bisected the problem and the error was on commit a51f7a6, wich enable rc6 by default (some time ago I have sent another bug about that). I have reverted the commit (the complete patch is attached) and now everything works great. Now, I have a Lenovo X201s, and if you need more information for debugging purpose just let me know, otherwise just apply the patch attached (on top of -rc4). If you prefer I can send the patch using git-send-email. Thanks Bye Francesco
