* objtool, drm/vmwgfx: Fix "duplicate frame pointer save" warningJosh Poimboeuf2016-06-081-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | objtool reports the following warnings: drivers/gpu/drm/vmwgfx/vmwgfx_msg.o: warning: objtool: vmw_send_msg()+0x107: duplicate frame pointer save drivers/gpu/drm/vmwgfx/vmwgfx_msg.o: warning: objtool: vmw_host_get_guestinfo()+0x252: duplicate frame pointer save To quote Linus: "The reason is that VMW_PORT_HB_OUT() uses a magic instruction sequence (a "rep outsb") to communicate with the hypervisor (it's a virtual GPU driver for vmware), and %rbp is part of the communication. So the inline asm does a save-and-restore of the frame pointer around the instruction sequence. I actually find the objtool warning to be quite reasonable, so it's not exactly a false positive, since in this case it actually does point out that the frame pointer won't be reliable over that instruction sequence. But in this particular case it just ends up being the wrong thing - the code is what it is, and %rbp just can't have the frame information due to annoying magic calling conventions." Silence the warnings by telling objtool to ignore the two functions which use the VMW_PORT_HB_{IN,OUT} macros.

* drm/vmwgfx: Report vmwgfx version to vmware.logSinclair Yeh2016-05-203-2/+25
| | | | | | | | | When tracking down a customer issue, it is useful to know exactly which version of the vmwgfx they are using. Since vmware.log is often the only available debug log, report vmwgfx version in there. Signed-off-by: Sinclair Yeh <syeh@vmware.com> Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com>
* drm/vmwgfx: Add VMWare host messaging capabilitySinclair Yeh2016-05-202-0/+607
| | | | | | | | | | | This patch adds capabilities for a VMWare guest to send and receive messages from the host, and adds functions to sending log messages to vmware.log and to request device settings that aren't available through the virtual hardware, e.g. certain settings in the VMX file.

* drm/vmwgfx: Kill some lockdep warningsThomas Hellstrom2016-05-205-14/+21
| | | | | | | | | | | | | Some global KMS state that is elsewhere protected by the mode_config mutex here needs to be protected with a local mutex. Remove corresponding lockdep checks and introduce a new driver-private global_kms_state_mutex, and make sure its locking order is *after* the crtc locks in order to avoid having to release those when the new mutex is taken.

Therefore rework the screen target code to correctly handle changes in framebuffer size and content_fb_type. Also make sure that we update the screen target correctly when the content_fb_type is not SAME_AS_DISPLAY.

From David Decotigny. 12) Introduce devlink, which can be used to configure port link types (ethernet vs Infiniband, etc.), port splitting, and switch device level attributes as a whole. From Jiri Pirko. 13) Hardware offload support for flower classifiers, from Amir Vadai. 14) Add "Local Checksum Offload". Basically, for a tunneled packet the checksum of the outer header is 'constant' (because with the checksum field filled into the inner protocol header, the payload of the outer frame checksums to 'zero'), and we can take advantage of that in various ways.

* drm/vmwgfx: Fix a width / pitch mismatch on framebuffer updatesThomas Hellstrom2016-01-141-1/+5
| | | | | | | | | | | | | | | | | When the framebuffer is a vmwgfx dma buffer and a proxy surface is created, the vmw_kms_update_proxy() function requires that the proxy surface width and the framebuffer pitch are compatible, otherwise display corruption occurs as seen in gnome-shell/native with software 3D. Since the framebuffer pitch is determined by user-space, allocate a proxy surface the width of which is based on the framebuffer pitch rather than on the framebuffer width.

| * drm/vmwgfx: Implement the cursor_set2 callback v2Thomas Hellstrom2015-12-087-18/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes native drm clients like Fedora 23 Wayland which now appears to be able to use cursor hotspots without strange cursor offsets. Also fixes a couple of ignored error paths. Since the core drm cursor hotspot is incompatible with the legacy vmwgfx hotspot (the core drm hotspot is reset when the drm_mode_cursor ioctl is used), we need to keep track of both and add them when the device hotspot is set. We assume that either is always zero. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Reviewed-by: Sinclair Yeh <syeh@vmware.com>
