[RFC PATCH] Increasing the max_leb_count

[RFC PATCH] Increasing the max_leb_count

[Karthik Ramanan]

Background:

* GLSDK brings in a lot of multimedia and graphics
  enabling components as well as example applications.
* Customers are going to add more software layers on top 
  of this to enable more feature rich graphics and multimedia. 
* There are two configurations that are used internally:
   ** Release filesystem
   ** Debug filesystem - (Release + GDB + dbg-pkgs)
      dbg-pkgs is basically the EXTRA_MACHINE_FEATURES in 
      the local.conf that brings in the sources and debug
      symbols to allow gdb debugging.

With the current leb_count it is not possible to support 
the above usecases. And to allow for enough room for the 
customer to add their components and not hit the space 
issue, it is proposed to make this change.

[RFC PATCH] dra7xx-evm: ubifs: Increase "max_leb_cnt"

[Karthik Ramanan]

    * This is need to allow some room for customers to build on top
      of the filesystem that we support 
    * This is needed for larger filesystem size to support dev image.

Vivek, Jake,

I suggested that Karthik sends an RFC to get your input on this matter. My 
concern is that we have large enough flash and enough storage space left for 
anything else you might want to store (e.g. backup/recovery images, etc.)

Please provide your feedback for this patch. Thanks.

Karthik, Denys,



Jake is currently out on vacation and will be back next week. Back in November, we started to see build failures creating the tisdk-rootfs, specifically when making the UBI filesystem because of max_leb_cnt.

Hence, Jake picked a value that was slightly greater than the reported minimum size required. The proposal to increase it to 5120 looks fine.



Regards,

Vivek
