2020-03-02drm/i915: Unify the DPLL ref clock frequency trackingImre Deak
All platforms using the shared DPLL framework use 3 reference clocks for their DPLLs: SSC, non-SSC and DSI. For a more unified way across platforms store the frequency of these ref clocks as part of the DPLL global state. This also allows us to keep the HW access reading out the ref clock value separate from the DPLL frequency calculation that depends on the ref clock. For now add only the SSC and non-SSC ref clocks, as the pre-ICL DSI code has its own logic for calculating DPLL parameters instead of the shared DPLL framework. v2: - Apply the ICL combo PHY PLL ref_clock/2 adjustment during the frequency->PLL param conversion direction as well.

2020-03-02drm/i915: Use intel_plane_data_rate for min_cdclk calculationStanislav Lisovskiy
There seems to be a bit of confusing redundancy in a way, how plane data rate/min cdclk are calculated. In fact both min cdclk, pixel rate and plane data rate are all part of the same formula as per BSpec. However currently we have intel_plane_data_rate, which is used to calculate plane data rate and which is also used in bandwidth calculations. However for calculating min_cdclk we have another piece of code, doing almost same calculation, but a bit differently and in a different place. However as both are actually part of same formula, probably would be wise to use plane data rate calculations as a basis anyway, thus avoiding code duplication and possible bugs related to this. Another thing is that I've noticed that during min_cdclk calculations we account for plane scaling, while for plane data rate, we don't. crtc->pixel_rate seems to account only for pipe ratio, however it is clearly stated in BSpec that plane data rate also need to account plane ratio as well. So what this commit does is: - Adds a plane ratio calculation to intel_plane_data_rate - Removes redundant calculations from skl_plane_min_cdclk which is used for gen9+ and now uses intel_plane_data_rate as a basis from there as well. v2: - Don't use 64 division if not needed(Ville Syrjälä) - Now use intel_plane_pixel_rate as a basis for calculations both at intel_plane_data_rate and skl_plane_min_cdclk(Ville Syrjälä) v3: - Again fix the division macro - Fix plane_pixel_rate to pixel_rate at intel_plane_pixel_rate callsites v4: - Renamed skl_plane_ratio function back(Ville Syrjälä) v5: - Don't precalculate plane pixel rate for invisible plane, check for visibility first, as in invisible case it will have dst_w and dst_h equal to zero, causing divide error. v6: - Removed useless warn in intel_plane_pixel_rate(Ville Syrjälä) - Fixed alignment in intel_plane_data_rate(Ville Syrjälä) - Changed pixel_rate type to be unsigned int in skl_plane_min_cdclk(Ville Syrjälä) Signed-off-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200227150935.2107-1-stanislav.lisovskiy@intel.com

2020-03-02video: Replace zero-length array with flexible-array memberGustavo A. R. Silva
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

2020-03-02IB/hfi1, qib: Ensure RCU is locked when accessing listDennis Dalessandro
The packet handling function, specifically the iteration of the qp list for mad packet processing misses locking RCU before running through the list. Not only is this incorrect, but the list_for_each_entry_rcu() call can not be called with a conditional check for lock dependency. Remedy this by invoking the rcu lock and unlock around the critical section. This brings MAD packet processing in line with what is done for non-MAD packets.

2020-03-02spi: bcm63xx-hsspi: Really keep pll clk enabledChristophe JAILLET
The purpose of commit 0fd85869c2a9 ("spi/bcm63xx-hsspi: keep pll clk enabled") was to keep the pll clk enabled through the lifetime of the device. In order to do that, some 'clk_prepare_enable()'/'clk_disable_unprepare()' calls have been added in the error handling path of the probe function, in the remove function and in the suspend and resume functions. However, a 'clk_disable_unprepare()' call has been unfortunately left in the probe function. So the commit seems to be more or less a no-op. Axe it now, so that the pll clk is left enabled through the lifetime of the device, as described in the commit.

2020-03-02drm/i915: Use a sentinel to terminate the dbuf slice arraysVille Syrjälä
Make life a bit simpler by sticking a sentinel at the end of the dbuf slice arrays. This way we don't need to pass in the size. Also unify the types (u8 vs. u32) for active_pipes.

2020-03-02drm/i915: Add missing commas to dbuf tablesVille Syrjälä
The preferred style is to sprinkle commas after each array and structure initialization, whether or not it happens to be the last element/member (only exception being sentinel entries which never have anything after them). This leads to much prettier diffs if/when new elements/members get added to the end of the initialization. We're not bound by some ancient silly mandate to omit the final comma.

Supposedly both src coordinates have to even when doing 90/270 degree rotation with RGB565. This is definitely true for the X coordinate (we just get a black screen when it is odd). My experiments didn't show any misbehaviour with an odd Y coordinate, but let's trust the spec and reject that one as well. v2: Ignore ccs hsub/vsub v3: Clarify the CCS special (Maarten) Deal with tgl+ CCS modifiers where we do need to look at hsub/vsub Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> #v2 Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200228160523.1064-1-ville.syrjala@linux.intel.com
