* drm/radeon/kms: handle !force case in connector detect more gracefullyAlex Deucher2011-11-111-0/+1
| | | | | | | | | | | | | | | | | | | commit d0d0a225e6ad43314c9aa7ea081f76adc5098ad4 upstream. When force == false, we don't do load detection in the connector detect functions. Unforunately, we also return the previous connector state so we never get disconnect events for DVI-I, DVI-A, or VGA. Save whether we detected the monitor via load detection previously and use that to determine whether we return the previous state or not.

* drm/radeon/kms: don't try to be smart in the hpd handlerAlex Deucher2011-08-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | commit d5811e8731213f80c80d89e980505052f16aca1c upstream. 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@amd.com> Signed-off-by: Dave Airlie <airlied@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* drm/radeon: Extended DDC Probing for Connectors with Improperly Wired DDC ↵Thomas Reim2011-08-151-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Lines (here: Asus M2A-VM HDMI) commit e384fab8c6f3ca88600bcb2ebdf0eb2f90864fab upstream. Some integrated ATI Radeon chipset implementations with add-on HDMI card (e. g. Asus M2A-VM HDMI) indicate the availability of a DDC even when the add-on card is not plugged in or HDMI is disabled in BIOS setup. In this case, drm_get_edid() and drm_edid_block_valid() periodically dump data and kernel errors into system log files and onto terminals. For these connectors DDC probing is extended by a check for a correct EDID header. Only in case a valid EDID header is also found, the (HDMI or DVI) connector will be used by the Radeon driver. This prevents the kernel driver from useless flooding of logs and terminal sessions with EDID dumps and error messages. This patch adds a flag 'requires_extended_probe' to the radeon_connector structure. In function radeon_connector_needs_extended_probe() this flag can be set on a chipset family/vendor/connector type specific basis. In addition, function radeon_ddc_probe() has been adapted to perform extended DDC probing if required by the connector's flag. Requires function drm_edid_header_is_valid() in DRM module provided by [PATCH] drm: Separate EDID Header Check from EDID Block Check.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some servers there is a hardcoded EDID provided in the vbios so that the driver will always see a display connected even if something like a KVM prevents traditional means like DDC or load detection from working properly. Also most server boards with DVI are not actually DVI, but DVO connected to a virtual KVM service processor. If we fail to detect a monitor via DDC or load detection and a hardcoded EDID is available, use it. Additionally, when using the hardcoded EDID, use a copy of it rather than the actual one stored in the driver as the detect() and get_modes() functions may free it if DDC is successful. This fixes the virtual KVM on several internal servers. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Cc: stable@kernel.org Signed-off-by: Dave Airlie <airlied@redhat.com>

* | drm: dumb scanout create/mmap for intel/radeon (v3)Dave Airlie2011-02-071-0/+1
|/ | | | | | | | | | | | | | | | | | | This is just an idea that might or might not be a good idea, it basically adds two ioctls to create a dumb and map a dumb buffer suitable for scanout. The handle can be passed to the KMS ioctls to create a framebuffer. It looks to me like it would be useful in the following cases: a) in development drivers - we can always provide a shadowfb fallback. b) libkms users - we can clean up libkms a lot and avoid linking to libdrm_*. c) plymouth via libkms is a lot easier. Userspace bits would be just calls + mmaps. We could probably mark these handles somehow as not being suitable for acceleartion so as top stop people who are dumber than dumb.

* drm/kms/radeon: Add support for precise vblank timestamping.Mario Kleiner2010-11-221-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds new functions for use by the drm core: .get_vblank_timestamp() provides a precise timestamp for the end of the most recent (or current) vblank interval of a given crtc, as needed for the DRI2 implementation of the OML_sync_control extension. It is a thin wrapper around the drm function drm_calc_vbltimestamp_from_scanoutpos() which does almost all the work and is shared across drivers. .get_scanout_position() provides the current horizontal and vertical video scanout position and "in vblank" status of a given crtc, as needed by the drm for use by drm_calc_vbltimestamp_from_scanoutpos(). The function is also used by the dynamic gpu reclocking code to determine when it is safe to reclock inside vblank. For that purpose radeon_pm_in_vbl() is modified to accomodate a small change in the function prototype of the radeon_get_crtc_scanoutpos() which is hooked up to .get_scanout_position(). This code has been tested on AVIVO hardware, a RV530 (ATI Mobility Radeon X1600) in a Intel Core-2 Duo MacBookPro and some R600 variant (FireGL V7600) in a single cpu AMD Athlon 64 PC.

| * | radeon, kdb, kms: Save and restore the LUT on atomic KMS enter/exitJason Wessel2010-10-061-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When changing VTs non-atomically the kernel works in conjunction with the Xserver in user space and receives the LUT information from the Xserver via a system call. When changing modes atomically for kdb, this information must be saved and restored without disturbing user space as if nothing ever happened.

| * | drm, kdb, kms: Add an enter argument to mode_set_base_atomic() APIJason Wessel2010-10-061-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some devices such as the radeon chips receive information from user space which needs to be saved when executing an atomic mode set operation, else the user space would have to be queried again for the information. This patch extends the mode_set_base_atomic() call to pass an argument to indicate if this is an entry or an exit from an atomic kernel mode set change. Individual drm drivers can properly save and restore state accordingly.

* drm/radeon/kms: remove useless clock codeAlex Deucher2010-09-021-1/+0
| | | | | | | | | | | This code was originally for forcing some clocks on certain asics. However, this code was later moved to asic specific functions for all of the affected asics. The only users of the original code at this point were r600, rv770, and evergreen and the code was not relevant for those asics. So, remove it.

| | | | | | | | | | On most newer asics, digital encoders have two links each and they can be used independantly. As such, treat them as separate encoders otherwise the individual links will not get programmed properly at modeset time.

* drm/radeon/kms: unify i2c handlingAlex Deucher2010-08-101-0/+11
| | | | | | | | | | | | Previously we added i2c buses as needed when enumerating connectors power management, etc. This only exposed the actual buses used and could have lead to the same buse getting created more than once if one buses was used for more than one purpose. This patch sets up all i2c buses on the card in one place and users of the buses just point back to the one instance.

| | | | | | | | | | | | | | | This connector attribute allows you to enable or disable underscan on a digital output to compensate for panels that automatically overscan (e.g., many HDMI TVs). Valid values for the attribute are: off - forces underscan off on - forces underscan on auto - enables underscan if an HDMI TV is connected, off otherwise default value is auto.
