Add name, category and description for each one of the 93 performance counters available on V3D. Note that V3D 4.2 has 87 performance counters, while V3D 7.1 has 93. Therefore, there are two performance counters arrays. The index of the performance counter for each V3D version is represented by its position on the array. Signed-off-by:

Follow the pattern of mipi_dsi_dcs_*_multi() and wrap several existing MIPI DSI functions to use the context for processing. This simplifies and streamlines driver code to use simpler code pattern. Note, msleep function is also wrapped in this way as it is frequently called inbetween other mipi_dsi_dcs_*() functions. Signed-off-by:

The modeset lock protects the DDC code from concurrent modeset operations, which use the same registers. Move that code from the connector helpers into the DDC helpers .pre_xfer() and .post_xfer(). Both, .pre_xfer() and .post_xfer(), enclose the transfer of data blocks over the I2C channel in the internal I2C function bit_xfer(). Both calls are executed unconditionally if present. Invoking DDC transfers from any where within the driver now takes the lock. Signed-off-by:

Managed cleanup with devm_add_action_or_reset() will release the I2C adapter when the underlying Linux device goes away. But the connector still refers to it, so this cleanup leaves behind a stale pointer in struct drm_connector.ddc. Bind the lifetime of the I2C adapter to the connector's lifetime by using DRM's managed release. When the DRM device goes away (after the Linux device) DRM will first clean up the connector and then clean up the I2C adapter. Signed-off-by:

The Starry HX83102 based mipi panel should never have been part of the boe tv101wum-n16 driver. Discussion with Doug and Linus in V1 [1], we need a separate driver to enable the hx83102 controller. In hx83102 driver, add DSI commands as macros. So it can add some panels with same control model in the future. In the old boe-tv101wum-nl6 driver inital cmds was invoked at the end of prepare() function , and call 0x11 and 0x29 at end of inital. For himax-hx83102 driver, we move 0x11 and 0x29 cmds invoked at prepare() function. Note:0x11 is mipi_dsi_dcs_exit_sleep_mode 0x29 is mipi_dsi_dcs_set_display_on [1]: https://lore.kernel.org/all/CACRpkdbzYZAS0=zBQJUC4CB2wj4s1h6n6aSAZQvdMV95r3zRUw@mail.gmail.comSigned-off-by: -

The NPU device consists of two parts: NPU buttress and NPU IP. Buttress is a platform specific part that integrates the NPU IP with the CPU. NPU IP is the platform agnostic part that does the inference. This separation enables support for multiple platforms using a single NPU IP, so for example NPU IP 37XX could be integrated into MTL and LNL platforms. Signed-off-by:

Consensus on the mailing lists is that panels shouldn't use a table of init commands but should instead use init functions.

This is because the innolux-p079zca panel driver didn't have as complex of a table and thus the old table was more efficient than the code. The bloat is still not giant (only 412 bytes). Also note that we can't direclty use mipi_dsi_generic_write_seq_multi() here because we need to deal with the crazy "nop" that this driver sends after all commands. This means that we have to write code that is "inspired" by the new macros. Since we're touching all the tables, let's also convert hex numbers to lower case as per kernel conventions. Reviewed-by:

The current mipi_dsi_*_write_seq() macros are non-intutitive because they contain a hidden "return" statement that will return out of the _caller_ of the macro. Let's mark them as deprecated and instead introduce some new macros that are more intuitive. These new macros are less optimal when an error occurs but should behave more optimally when there is no error. Specifically these new macros cause smaller code to get generated and the code size savings (less to fetch from RAM, less cache space used, less RAM used) are important. Since the error case isn't something we need to optimize for and these new macros are easier to understand and more flexible, they should be used. After converting to use these new functions, one example shows some nice savings while also being easier to understand. $ scripts/bloat-o-meter \ ...after/panel-novatek-nt36672e.ko \ ...ctx/panel-novatek-nt36672e.ko add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-988 (-988) Function old new delta nt36672e_1080x2408_60hz_init 6236 5248 -988 Total: Before=10651, After=9663, chg -9.28% Reviewed-by:

Through a cooperative effort between Hsin-Yi Wang and Dmitry Baryshkov, we have realized the dev_err() in the mipi_dsi_*_write_seq() macros was causing quite a bit of bloat to the kernel. Let's hoist this call into drm_mipi_dsi.c by adding a "chatty" version of the functions that includes the print. While doing this, add a bit more comments to these macros making it clear that they print errors and also that they return out of _the caller's_ function. Without any changes to clients this gives a nice savings. Specifically the macro was inlined and thus the error report call was inlined into every call to mipi_dsi_dcs_write_seq() and mipi_dsi_generic_write_seq(). By using a call to a "chatty" function, the usage is reduced to one call in the chatty function and a function call at the invoking site. Building with my build system shows one example: $ scripts/bloat-o-meter \ .../before/panel-novatek-nt36672e.ko \ .../after/panel-novatek-nt36672e.ko add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-4404 (-4404) Function old new delta nt36672e_1080x2408_60hz_init 10640 6236 -4404 Total: Before=15055, After=10651, chg -29.25% Note that given the change in location of the print it's harder to include the "cmd" in the printout for mipi_dsi_dcs_write_seq() since, theoretically, someone could call the new chatty function with a zero-size array and it would be illegal to dereference data[0]. There's a printk format to print the whole buffer and this is probably more useful for debugging anyway. Given that we're doing this for mipi_dsi_dcs_write_seq(), let's also print the buffer for mipi_dsi_generic_write_seq() in the error case. It should be noted that the current consensus of DRM folks is that the mipi_dsi_*_write_seq() should be deprecated due to the non-intuitive return behavior. A future patch will formally mark them as deprecated and provide an alternative. Reviewed-by:
