drm_file.master should be protected by either drm_device.master_mutex or drm_file.master_lookup_lock when being dereferenced. However, drm_master_get is called on unprotected file_priv->master pointers in vmw_surface_define_ioctl and vmw_gb_surface_define_internal. This is fixed by replacing drm_master_get with drm_file_get_master. Signed-off-by:

For framebuffers with non-zero offset fields, shadow-plane helpers provide a pointer to the first byte of the contained data. Use it in vkms. Also provide use the offset-adjusted data address for the writeback job's output buffers. Output framebuffers with non-zero offsets now have their content written to the correct location.

The fields in struct mgag200_pll_values currently hold the bits of each register. Store the PLL values instead and let the PLL-update code figure out the bits for each register. Until now, the compute function either stored plain values or register bits in struct mgag200_pll_values. The rsp update function used the values as-is. This made it very hard to correctly interpret the stored values (e.g., for logging or debugging). With the cleanup, the stored values now have a clear meaning. v2: * add a bit more context in the commit message (Sam) Signed-off-by:

The S parameter is controls the loop filter bandwidth when programming the PLL. It's currently stored as part of P (i.e., the clock divider.) Add a separate variable for S prepares the PLL code for further refactoring. The value of s is currently 0, so it has not yet an effect on the programming. v2: * add a note on the current value of s to commit message Signed-off-by:

The _set_plls() functions compute a pixel clock's PLL values and program the hardware accordingly. This happens during atomic commits. For atomic modesetting, it's better to separate computation and programming from each other. This will allow to compute the PLL value during atomic checks and catch unsupported modes early. Split the PLL setup into a compute and an update functions, and call them one after the other. Computed PLL values are store in struct mgag200_pll_values. There are four parameters for the PLL, m, n, p and s. Every compute function stores a value for each of these parameters, and the rsp update function makes the register bits from them. The values stored by the compute function are either plain values or register bits. An additional change is required to always store plain values. No functional changes. Signed-off-by:

Put the clock-selection code into each of the PLL-update functions to make them select the correct pixel clock. Instead of copying the code, introduce a new helper WREG_MISC_MASKED, which does masked writes into <MISC>. Use it from each individual PLL update function. The pixel clock for video output was not actually set before programming the clock's values. It worked because the device had the correct clock pre-set. v2: * don't duplicate <MISC> update code (Sam) Signed-off-by:

In drm_is_current_master_locked, accessing drm_file.master should be protected by either drm_file.master_lookup_lock or drm_device.master_mutex. This was previously awkward to assert with lockdep. Following patch ("locking/lockdep: Provide lockdep_assert{,_once}() helpers"), this assertion is now convenient. So we add in the assertion and explain this lock design in the kerneldoc.
