Summary: [radeon-rewrite] TexImage2D, SGIS_generate_mipmap,
pixels=NULL
Product: Mesa
Version: unspecified
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/DRI/Radeon
AssignedTo: [email protected]
ReportedBy: [email protected]
When mipmap generation is enabled, if NULL is passed for pixels to TexImage2D,
then then a crash occurs because the code attempts to generate a mipmap but
there is no source data for the image yet.
Note: I updated TexSubImage2D correspondingly, even though pixels=NULL is not
allowed for TexSubImage2D, for code consistency and because it appears that
pixels=NULL is not currently caught by the wrapper code and is otherwise a
no-op, so it's better not to crash just for this.
