[PATCH v3 0/3] Fix SW_TABLET_MODE detection method

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The intension for this patch was to address SW_TABLET_MODE detection 
problem.  It is during the initial investigation; two other issues were 
identified and are related to the initial task.  

First, several WMI queries were reporting error 0x05 including 
HPWMI_HARDWARE_QUERY that is responsible for returning dock and table 
modes values. See patch v3 part 2 comments for list of WMI queries 
affected.  The driver now reports the appropriate states and values 
correctly.

Lastly, a limiting data size restriction was discovered. 
struct bios_args data member size limits all possible WMI commands 
to those requiring buffer size of 128 bytes or less.  Several WMI 
commands and queries require a buffer size larger than 128 bytes 
hence limiting current and new feature supported by the driver. 
hp_wmi_perform_query function changed to handle the memory 
allocation and release of any required buffer size. 


Jorge Lopez (3):
  Fix SW_TABLET_MODE detection method
  Fix 0x05 error code reported by several WMI calls
  Changing bios_args.data to be dynamically allocated
